Project Goals

Improve Safety of Traffic flow (Vehicular and Pedestrian)

Control Excessive Traffic Speeding

Address Traffic Congestion and Queuing problems during School peak hours

Improve Drainage and inadequate Storm Sewer system

Project Needs

Excessive Speeding along 156th Street

171 traffic citations (2006); 199 citations (2007); 150 citations (2008); 135 citations (Jan-June 2009) Speed Records along 156th Street

for 2008 - 81 mph for 2009 - 59 mph

Speed – Drivers Cone of Vision

40 mph 40 mph 30 mph 30 mph 20 mph 20 mph

Project Needs

Poor Traffic Operations and Queuing during school peak hours.

Project Needs

Drainage – Open Ditches and existing storm sewer inadequate causing runoff and flooding.

Project Needs

Roadway – 156th Street Pavement rapidly degrading. No resurfacing or rehab done in the last 15-20 years.

Project Alternatives

No-Build AlternativeNo-Build Alternative

Current 2-lane section along 156th St 4-way stop at 156th St & Bennington

Rd Does not improve traffic operations,

excessive speeding and queuing issues

Does not improve safety of Pedestrian/ Bicycles

Drainage problems will continue to exist

Project Alternatives

Build AlternativesBuild Alternatives Widen 156th Street to a 3-lane roadway

with a center left-turn lane Provides additional capacity to handle future

volumes and queuing at School Provides a refuge lane for left-turning

vehicles Provides a transition area for medians and

landscaping – shorter pedestrian crossings Traffic Calming like Chicanes (curved

roadway) can be effectively incorporated to slow traffic

Project Alternatives

Incorporate ‘Traffic Calming’ elements to control excessive speeding Chicanes (Curved Roadway) Medians Landscaping, Trees Roundabouts etc.

Project Alternatives

Build AlternativesBuild Alternatives Install a Traffic Signal at 156th St & Bennington Rd

More Right-of-way needed to install exclusive left-turn lanes Volumes do not meet ‘Federal Traffic Signal Warrants’ till

2030 – No federal money can be used

Project Alternatives

Build AlternativesBuild Alternatives Install a Roundabout at 156th St & Bennington Rd

Excellent traffic control to reduce speeds (15-20 mph) Good pedestrian crossings – Shorter crossing distance with

refuge medians (one lane at a time) ADA compliant design Eligible for federal funding Functions as a ‘Gateway’ from South

North Segment

Chicanes

Curved Roadways to break drivers

line-of-sight

and

Slow drivers
