Project Level Traffic Management Plan 7/31/2018 OR140: Klamath County Boat Marina to Lakeshore Drive Page 1

EXECUTIVE SUMMARY

The Lake of the Woods Highway (OR140) is a state highway that traverses the Cascade Mountain Range in the

southern portion of the state between the cities of Medford and Klamath Falls. It is an important highway for

recreational traffic, providing access to timber lands, residential properties, the Fremont-Winema National

Forest, Rogue Siskiyou National Forest, Klamath Lake, and other various recreational facilities and can be used

as an alternate route to Crater Lake National Park. It is also designated as a freight route between Medford

and Lakeview. Keeping the highways safe and traffic moving are critical goals of the Oregon Department of

Transportation.

The purpose of the OR140: Klamath County Boat Marina-Lakeshore Drive project is to increase safety

measures along Klamath Lake to better accommodate current and future traffic volumes. Currently, there are

no protective measures to prevent vehicles from leaving the highway and going into the lake. Along with this,

the roadway is too narrow and does not provide opportunities for bicycle use. Right-of-way widths through

this stretch of road are 80-120 feet and change often. This project will address all of these issues by widening

the roadway farther into the lake with new embankments, thus allowing for wider lanes (12’), wider shoulders

(6’) with rumble strips, and the installment of guardrails. Curve realignment, additional parking along the lake,

a wetland mitigation area, and an information kiosk for the Volcanic Legacy Scenic Byway will also be

constructed.

Construction staging is anticipated to consist of 24-hour single lane closures controlled by a combination of

temporary portable traffic signals and flaggers depending on the location characteristics. Based on the analysis

completed, Region 4 Traffic recommends allowing the use of temporary portable signals in construction stages

that are no more than 1,600 feet in length and contain no intersections or driveways in between signals.

Locations not meeting these requirements will utilize 24-hour flagger controlled single lane closures. If flagging

is being used to control traffic, closure lengths of up to 1 mile between Running Y Road and Lakeshore Drive or

2 miles between the Klamath County Boat Marina and Running Y Road are recommended. Due to traffic

volumes, closures longer than 1600 feet for signals, or the specified 1 or 2 miles for flagging, should not be

allowed. On days found to have holiday or special event traffic, a flagger may be used temporarily. The project

section of OR140 has not been identified in a Corridor-Level TMP and therefore uses a maximum average

delay threshold of 20 minutes.

Due to the existing roadway width, the horizontal clearance during all stages of construction must be limited

to 16 feet between the edge of pavement and the temporary traffic control device (anticipated as a hard

barrier). This minimum clearance will accommodate annually permitted vehicles at all times and may

accommodate single trip permits up to 14 feet wide. Single Trip Permits requiring greater horizontal clearance

would be evaluated on a case by case determination. This route does not allow annual trip permits for over-

height loads. Single trip permits should be evaluated to ensure that vertical clearances can be maintained

under the proposed temporary portable signal, which has a minimum height of 17 feet.

The contractor will be required to notify ODOT Motor Carrier Transportation Division at least 35 days prior to

any restriction (width, height, length, weight) taking place. The notification should be submitted online

through the “Highway Restriction Notice-Size and/or Weight” form (Form No. 734-2357) that is available from

the ODOT Motor Carrier Transportation web site.


1 INTRODUCTION

1.1 TMP Goals

The purpose of this Project Level Traffic Management Plan (TMP) is to address construction related traffic

impacts for the OR140: Klamath County Boat Marina to Lakeshore Drive project. The report will focus on

traffic volume data analysis, construction staging, work zone lane restrictions, and traffic management and

operation strategies.

This document will provide the details behind the development of the project’s Traffic Control Plan (TCP) and

other measures that will be put in place for construction to minimize disruptions to motorists, bicyclists, the

freight industry and communities without compromising public or worker safety, or the quality of the work

being performed.

The TMP will incorporate the following elements to accomplish the purpose:

1.2 Project Purpose and Need, Goals and Objectives

The Lake of the Woods Highway (OR140) is a state highway that traverses the Cascade Mountain Range in the

southern portion of the state between the cities of Medford and Klamath Falls. It is an important highway for

recreational traffic, providing access to timber lands, residential properties, the Fremont-Winema National

Forest, Rogue Siskiyou National Forest, Klamath Lake, and other various recreational facilities and can be used

as an alternate route to Crater Lake National Park. It is also designated as a freight route between Medford

and Lakeview. Keeping the highways safe and traffic moving are critical goals of the Oregon Department of

Transportation.

The purpose of this project is to increase safety measures along Klamath Lake to better accommodate current

and future traffic volumes. Currently, there are no protective measures to prevent vehicles from leaving the

highway and going into the lake. Along with this, the roadway is too narrow and does not provide

opportunities for bicycle use. Right-of-way widths through this stretch of road are 80-120 feet and change

often. This project will address all of these issues by widening the roadway farther into the lake with new

embankments, thus allowing for wider lanes (12’), wider shoulders (6’) with rumble strips, and the installment

of guardrails. Curve realignment, additional parking along the lake, a wetland mitigation area, and an

information kiosk for the Volcanic Legacy Scenic Byway will also be constructed.


2 PROJECT AREA CHARACTERISTICS

2.1 Study Area Boundaries

This project is in Klamath County approximately five miles west of the City of Klamath Falls. The project limits

stretch 5.7 miles along OR140 from mile point 56.92 near the Klamath County Boat Marina to mile point 62.64

just northwest of Lakeshore Drive. A vicinity map indicating the project boundaries has been provided below

in Error! Reference source not found. and 2.

2.2 Transportation Facility, Existing Conditions

According to the 1999 Oregon Highway Plan (OHP), the project sections of OR140 are classified as a Reduction

Review Route, a designated OHP Freight Route, a Federally Designated Truck Route, and a Scenic Byway

(Volcanic Legacy Scenic Byway) on the National Highway System. Additionally, OR140 is classified as a Rural

Principal Arterial according to the 2018 ODOT Functional Classification and National Highway System Status.

The project sections of OR140 follow a “summer” trend characterized by peak traffic volumes in the summer

months (ODOT ATR Characteristic Trend Map). Within the project limits, OR140 is an undivided two-lane, two-

way highway with occasional driveway access. In the location of Running Y Road intersection there are

additional turning lanes in each direction with stop-controlled access at Running Y Road. Typical OR140

existing horizontal roadway widths are summarized below in Error! Reference source not found..

2.3 Traffic Volumes and Truck Percentage

The 2017 Average Annual Daily Traffic (AADT) along this section of highway ranges from 3,000 to 3,800

vehicles per day, with trucks accounting for 26.12% of the AADT (2017 OTMS Traffic Volumes and Vehicle

Classification).

2.4 Posted Speed

The posted speed throughout the project section of OR140 is 55mph.

3 WORK ZONE TRAFFIC ANALYSIS FINDINGS

As part of the construction staging, 24-hour single lane closures are required. Most of the stages will be

controlled by a temporary portable signal, while some with inadequate sight distance or intersecting streets

and driveways, will be controlled by flaggers. The following sections break down the analysis based on these

two types of traffic control methods.

3.1 Flagger Work Zone Analysis

The analysis was conducted using traffic volumes from the Lake of the Woods Automatic Traffic Recorder (ATR

15-020) located at MP 16.03 on OR140 (Lake of the Woods Highway #270). Using the 2017 OTMS Traffic

Volumes and Vehicle Classification system, AADT volumes from two locations within the project limits were

gathered and compared to the Lake of the Woods ATR’s AADT. Results from the comparison found that

between Running Y Road and Lakeshore Drive, the ATR data needed an adjustment factor of 1.20, while for

the rest of the project; a 0.95 adjustment factor was needed. Based on monthly data from the ATR summary,

peak traffic volumes (non-holiday) on this route typically occur in August, therefore August, 2016 data was

utilized for this analysis. 2017 data was not utilized due to inconsistent patterns due to the solar eclipse and

winter storms.


ATR volumes were further adjusted to the 2020 construction year assuming a conservative annual growth rate

of 5.51% (based on the 2013-2017 ATR 15-020 annual history) and converted to Passenger Car Equivalent

(PCE) values assuming a PCE factor of 3.0 and an average truck percentage of 26.12% (2017 OTMS Traffic

Volumes and Vehicle Classification). Using ODOT work zone traffic analysis methodologies, the average delays

anticipated during flagger controlled single lane closures were estimated in order to identify typical traffic

patterns throughout the week and ultimately determine the appropriate lane restrictions for the identified

project segment.

The result of this analysis indicates that flagger controlled single lane closures can be allowed as follows:

Klamath County Boat Marina to Running Y Road (MP 56.92 – 61.68): Closures 2 miles in length or less

can be allowed any time of the year, Sunday through Saturday, 24 hours a day.

Running Y Road to Lakeshore Drive (MP 61.68 – 62.64): Closures 2 miles in length or less can be

allowed from Labor Day to Memorial Day (non-summer), Sunday through Saturday, 24 hours a day.

Closures 1 mile in length or less can be allowed any time of the year, Sunday through Saturday, 24

hours a day

Average delay estimates as a result of flagger controlled single lane closures range from 2-6 minutes (delay

threshold for the corridor is 20 minutes) and 95% max queue lengths range from 0.50 – 1.00 miles. Due to

traffic volumes, closures longer than those stated above should not be allowed.

3.2 Temporary Portable Signal Work Zone Analysis

The analysis was conducted using traffic volumes from the Lake of the Woods Automatic Traffic Recorder (ATR

15-020) located at MP 16.03 on OR140 (Lake of the Woods Highway #270). Using the 2017 OTMS Traffic

Volumes and Vehicle Classification system, AADT volumes from two locations within the project limits were

gathered and compared to the Lake of the Woods ATR’s AADT. Results from the comparison found that

between Running Y Road and Lakeshore Drive, the ATR data needed an adjustment factor of 1.20, while for

the rest of the project; a 0.95 adjustment factor was needed. ATR data from throughout the year of 2016 was

utilized for this analysis. 2017 data was not utilized due to inconsistent patterns due to the solar eclipse and

winter storms.

ATR volumes were further adjusted to the 2020 construction year assuming a conservative annual growth rate

of 5.51% (based on the 2013-2017 ATR 15-020 annual history) and converted to Passenger Car Equivalent

(PCE) values assuming a PCE factor of 3.0 and an average truck percentage of 26.12% (2017 OTMS Traffic

Volumes and Vehicle Classification). Using traffic signal modeling with the parameters of a 180 second max

cycle length, the average delays anticipated during temporary portable signal controlled lane closures were

estimated in order to identify typical traffic patterns throughout the week and ultimately determine the

appropriate lane restrictions for the identified project segment.

The result of this analysis indicates that temporary portable traffic signal controlled lane closures no more

than 1600 feet in length can be allowed Sunday – Saturday, at any time. Modeling analysis found a minimum

green time of 25 seconds, a yellow time of 5 seconds, and a red time varying between 30 and 55 seconds


depending on length between temporary portable signals and vehicle speed. Average delay estimates as a

result of temporary portable traffic signal controlled lane closures of no more than 1600 feet range from 4-10

minutes (delay threshold for the corridor is 20 minutes). Due to traffic volumes, closures longer than 1600 feet

in length should not be allowed.

4 FACTORS IMPACTING TRAFFIC AND CONSTRUCTION STAGING

The project is scheduled for construction in three seasons from June 2020 to December 2022 (Note: Winter

construction shut-down periods from December-February when road will be fully opened). The following is an

overview of the factors that have potential impacts on traffic and construction staging.

4.1 Proposed Impacts to Traffic Flow

The proposed impacts to traffic flow include 24-hour single lane closures with alternating one-way traffic

controlled by either temporary portable signals or flaggers with subsequent delays, a reduction in horizontal

roadway clearances, and intermittent closures of the Boat Marina access during construction activities.

4.2 Existing Restrictions

Corridor-Level Traffic Management Plans (TMPs) are established for routes in Oregon where delays and access

issues may result in significant negative mobility and economic impacts to motorists, the freight industry,

individual businesses and communities. The project section of OR140 has not been identified in a Corridor-

Level TMP and therefore an established average delay threshold of 20 minutes is used for the project section.

Work activities are anticipated to occur during the day as nighttime work may not be permitted along Upper

Klamath Lake due to environmental permitting restrictions. In addition, much of the work schedule will be

controlled by the Oregon Departments of Fish and Wildlife’s Guidelines for Timing on In-Water Work to Protect

Fish and Wildlife Resources (June 2008). According to Western Federal Lands (WFL), the in-water work period

for this project is July 1 through January 31.

4.3 Projects Identified for Potential Coordination Needs

Consideration and coordination efforts should be made to reduce corridor impacts and delays as a result of

multiple projects being performed on OR140 during the 2020-2022 construction seasons. The following

projects have been identified as potential candidates for impacting OR140 corridor during the 2020

construction season:

OR140: Lake of the Woods – Safety improvements near MP 47 (Bid let 6/4/2020 – impacts TBD)

The following projects have been identified as potential candidates for impacting the OR140 corridor during

the 2021 construction season:

OR140: Lake of the Woods – Safety improvements near MP 47 (Bid let 6/4/2020) – construction may

continue into 2021

The following projects have been identified as potential candidates for impacting the OR140 corridor during

the 2022 construction season:

No projects have been identified as potential candidates for impacting the OR140 corridor.


4.4 Alternate/Detour Routes

Due to the nature and location of the construction activities, highway closures are not anticipated. Therefore,

no detour routes have been identified.

4.5 Holidays and Special Events

Holidays and seasonal events may impact traffic in the project area. The major holidays are included as

standard restrictions in the 2018 Oregon Standard Specifications for Construction section 00220.40(e-2a)

which includes applicable provisions for lane restrictions. Local and seasonal events requiring unique lane

restrictions will be identified (if applicable) in the project special provisions section 00220.40(e-2b).

The following special events have been identified and should be listed as additional items in the 00220.40(e-

2b) special provision section:

None identified impacting traffic management

5 POTENTIAL MOBILITY ISSUES

5.1 Traffic Mobility During Construction

OR140 is used by recreational traffic, some commuting traffic between Klamath Falls and Medford, and freight

traffic for local and long haul trips. Special consideration for all traffic and freight accessibility through the

project area is necessary.

5.2 Consideration of Over-Sized Vehicles

OR140 is part of the National Highway System and is classified as a federally designated Freight Route and

Truck Route (1999 OHP). The Freight Mobility Map identifies OR140 as a “Blue Route,” indicating that the

route is generally unrestricted for standard freight traffic, but has weight or width restrictions for non-divisible

and/or heavy haul loads. This section of OR140 is not approved for continuous movement of over-height

freight vehicles (not designated as a High Clearance Route). The route is a 12’ Wide Annual Route during

daytime hours and allows continuous trip routes for widths up to 10’ during nighttime hours. Nighttime is

defined as ½ hour after sunset until ½ hour before sunrise.

The construction staging is anticipated to include 24-hour single lane closures, either controlled by temporary

portable signals or flaggers. Due to the existing roadway width, the horizontal clearance during all stages of

the construction must be limited to 16 feet between the edge of pavement and the temporary traffic control

device (anticipated as a hard barrier). This minimum clearance will accommodate annually permitted vehicles

at all times and may accommodate single trip permits up to 14 feet wide. Single trip permits requiring greater

horizontal clearance would be evaluated on a case by case determination.

This route does not allow annual trip permits for over-height loads. Single trip permits should be evaluated to

ensure that vertical clearances can be maintained under the proposed temporary portable signal, which has a

minimum height of 17 feet.


A written notification using the on-line electronic restriction notice Form 734-2357 must be submitted to the

MCTD Freight Mobility Coordinator when a project restricts the width, length, height, or weight of vehicles

through a work zone or detours trucks around a work zone.

For horizontal width, MCTD requires notification when reducing the horizontal clearance on a National

Highway System route to less than the clearances listed below:

Less than 28 feet for two lanes of one-way traffic (single lane in each direction)

Less than 22 feet for one lane of one-way traffic

Horizontal clearance is measured across the road from any fixed object to the face of a guardrail, barrier or

other fixed object.

6 CONSTRUCTION STAGING AND WORK ZONE TRAFFIC CONTROL

Lane closures and temporary traffic control will be implemented according to the 2018 Oregon Standard

Specifications for Construction, sections 00220 and 00225 of the Project Special Provisions and the ODOT

TM800 series Standard Drawings.

Due to the nature of the roadway widening and lake infill, construction is anticipated to consist of reducing

the number of travel lanes to single lane 24-hours a day and controlling traffic flow with either temporary

portable signals or flaggers. The project is split into three schedules, each with shifting stages that utilize one

of the temporary traffic control methods above. See the attached Staging Segments and TMP Notes for Plans

provided by Western Federal Lands.

The first phase of Schedule A will close the westbound traffic lane along the lake portion of the project (MP

56.92 – 58.76) while the embankment is being constructed and surcharged. The second phase of Schedule A

would alternate closing the westbound and eastbound traffic lane along the same portion of the project as the

highway is widened, repaved, and the guardrail is constructed. Schedule B and C would also alternate closing

the westbound and eastbound traffic lane while the highway is widened and one of the curves is realigned

(MP 58.76 – 62.64).

Bicycle and Pedestrian volumes are anticipated to be low due to the rural location of the project and the

current absence of roadway shoulders. However they will still need to be accommodated in accordance with

the 2018 Standard Specification section 00220.02(b). If Pedestrians and Bicyclists are traveling this section of

OR140, they are currently utilizing the edge of the traffic lane. The Temporary Pedestrian Accessible Route

Plan (TPAR) will consist of temporary striping of a minimum 4-foot shoulder along the single lane of travel

through all of the construction stages.


7 WORK ZONE LANE RESTRICTIONS

Based on the analysis completed, Region 4 Traffic recommends allowing the reduction of traffic to one lane for

a length of no more than 1600 feet with the use of temporary portable signals and contains no intersections or

driveways in between signals. Locations not meeting these requirements will utilize 24-hour flagger controlled

single lane closures. If flagging is being used to control traffic, closure lengths of up to 1 mile between Running

Y Road and Lakeshore Drive or 2 miles between the Klamath County Boat Marina and Running Y Road are

recommended. Due to traffic volumes, closures longer than 1600 feet for portable temporary signals, or the

specified 1 or 2 miles for flagging, should not be allowed. On days found to have holiday or special event

traffic, a flagger may be used temporarily.

8 TRAFFIC MANAGEMENT AND OPERATIONS

In order to minimize construction impacts to the traffic flow on OR140 and promote work zone safety, the

following traffic management and operation strategies should be considered to support the construction

activities of the project.

8.1 Public Information and Outreach

Public information and outreach is beneficial for maintaining public support for projects as well as encouraging

changes in travel behavior during project construction. Keeping the public aware of delays as they occur may

encourage local motorists to use alternate routes. This will help manage congestion throughout the project.

The ODOT Region 4 community liaison representative will be responsible for communicating the project’s

goals and impacts to citizens, elected officials, freight community, businesses, and to the traveling public.

8.2 Motorist Information

Portable Changeable Message Signs (PCMS): A PCMS is a portable electronic sign that can be used to

display changeable messages. These signs can be used to inform drivers of upcoming construction

periods and warn drivers of construction activities as needed.

Ground Mounted Signs: Signs can be installed at the endpoints of work zones to inform motorists of

road construction.

TripCheck (ODOTs Website): TripCheck allows motorists to access real time information and weather

conditions through the Internet. Motorists may also call 511 to receive this information.

8.3 Construction Strategies

Construction Zone Enhanced Enforcement Program: To be evaluated by Construction PM dependent

on funding availability and priority projects.

On-Site Communications: ODOT personnel will be on site during construction activities. Cell phones

and/or State Radio communications will be maintained to report incidents within the work zone.


Coordination with Adjacent Construction Projects: To minimize corridor delay, the contractor and

ODOT will coordinate lane closures with other adjacent projects that may impact traffic during

construction.

Temporary Work Zone Speed Reduction: Reduced speed zoning on entrance to work zone. Requires

State Traffic Engineer approval.

8.4 Incident Management

Incident management is a planned and coordinated program that detects and removes incidents from the

highway and restores traffic capacity as safely and quickly as possible. If an incident occurs during the

construction of the project, the inspector will call the Region Dispatch Center (541-383-0121) and the

appropriate actions will be taken. All emergency vehicles will be allowed immediate passage through the

project at all times.

9 COMMUNICATION PLAN

The primary goal of the communications effort for this project is to inform project stakeholders and highway

users of scheduled construction activities and expected impacts. The Region 4 ODOT Community Liaison

Representative and Project Manager will coordinate with the public and project stakeholders throughout the

design and construction process.

The following table represents typical communication that should occur between stakeholders throughout the

project:
