Project Location
The routes under study have both regional and interstate significance. IL 47 is primarily a rural north–south state highway that runs from central Illinois to Wisconsin for a distance of approximately 170 miles. I‐88 is an interstate that runs from western Illinois to metropolitan Chicago for a distance of approximately 140 miles. This section of I‐88 is under the jurisdiction of the Illinois Tollway and is designated the Reagan Memorial Tollway. Since 2010, all of I‐88 has been part of the Chicago–Kansas City Expressway (CKC) and designated Illinois Route 110. The study area includes the Village of Sugar Grove and unincorporated Blackberry and Sugar Grove Townships.

PROJECT PHASES
Roadway projects are typically implemented in three distinct phases. Phase one includes preliminary engineering & environmental studies. During this phase, issues and concerns are identified; solutions are proposed; and the public is engaged. Phase one typically takes 3‐5 years to complete. Phase two includes contract plan preparation and land acquisition. Phase two typically takes two years to complete. Phase three is the construction phase, which is most visible to the public. Phase three typically takes two to three years to complete and is subject to funding availability. This project is currently in phase one. Project costs will be developed as part of this study. This improvement is partially funded in IDOT’s FY 2017‐2022 Proposed Highway Improvement Program and requires additional local cost participation to advance beyond Phase I.

ENVIRONMENTAL PROCESS
This project is being studied in accordance with the National Environmental Policy Act (NEPA) of 1969. Compliance with this act has allowed the project study to be funded with federal dollars and will also allow future phases to be paid for, in‐part, with federal dollars. A full range of reasonable alternatives, including the “no‐build” alternative are under consideration. The project team also coordinates with environmental resource agencies and comprehensive environmental reviews are being performed. Findings will be documented and made available for public review in an Environmental Assessment (EA) document.

STUDY GROUPS
RESOURCE AGENCIES
There are three general groups that are participating in this Phase I Study. The Project Study Group, P‐S‐G, the Resource Agencies, and the balance of stakeholders, which includes the general public and the Community Advisory Group, often referred to as the CAG. The PSG collects and analyzes data, promotes partnership, and ensures requirements are met. The Resource Agencies help identify issues of environmental and socioeconomic concern as well as provide input on the purpose & need, alternatives, and the sufficiency of environmental analysis. The role of the public and CAG is to advise the P‐S‐G on issues related to the design, throughout the entire study process. The CAG has met four times since the project began.

Alternatives Carried Forward
The alternative development and evaluation process is a continuous process with multiple rounds of evaluation. Alternatives have been screened out through the process based upon their characteristics. Alternatives started with a low amount of detail at the beginning of the process and have increased in detail as they passed through each round of evaluation. The process started with addressing how well each alternative addresses the project transportation needs as identified in the Purpose and Need statement. Further rounds of evaluation screened alternatives based upon transportation needs, additional pedestrian safety elements, environmental factors, community factors, and costs.

8 Build Alternatives + 1 No-Build
Illinois Route 47 alternatives had a combination of design considerations including, the alignment – where does Illinois 47 go, and the typical section – what does Illinois 47 look like. Four alignment alternatives of Illinois Route 47 were combined with certain typical section alternatives for evaluation. A total of eight Illinois 47 build alternatives were evaluated in two rounds. The no‐build alternative was carried through both rounds of evaluation for comparison purposes.

For the no‐build alternative, the existing typical section includes 4 travel lanes at Waubonsee Community College and at the interchange with I‐88. Everywhere else the typical section has 2 travel lanes and no median. The median at Waubonsee Community College is a 50 feet wide with inside shoulders and ditch. The median at the interchange is 22 feet wide with raised curb median.

The second build alternative to be carried forward is alternative M‐1C. It includes the same attributes as the previous alternative except when adjacent to the Forest Preserve. At the forest preserve the median is narrowed from 30 feet wide to 22 feet wide in order to minimize forest preserve impacts.

The third build alternative to be carried forward is alternative M‐2C. It includes the same typical section at the Forest Preserve as the previous alternative. At areas other than the forest preserve, it has a 30 foot wide median but the widening of the road is shifted toward the east to minimize residential impacts. The existing roadway centerline generally becomes the center of the southbound lanes.

Seven new interchange alternatives were evaluated in addition to the no‐build existing partial access interchange. More information on the interchange screening can be found in the next room. Interchanges 5, 6 and 7, which included variations of partial cloverleaf interchanges with loop ramps in the southeast and southwest quadrants, were eliminated during the screening. This left four new interchange alternatives to be carried forward, numbered 1 thru 4, in addition to the no‐build alternative. All of the interchanges accommodate pedestrians and bicycles on IL 47 crossing I‐88. We are seeking your input on these alternatives today.
18
NO-BUILDEXISTING HALF DIAMOND
NB
Partial Access (only to and from west)
Poor Driver Expectancy
Doesn’t Meet Purpose and
Need
The existing interchange configuration is a half diamond with access only to and from the west. This alternative was carried forward for comparison purposes to the build alternatives. The northern intersection is free‐flow with northbound to westbound (left turning) traffic yielding to southbound traffic. The southern intersection is under stop control with IL 47 under free flow conditions and the eastbound exit ramp under stop control.

CONVENTIONAL DIAMOND I-1
Stop Signs Short Term
Traffic Signals Long
Term
Requires Bridge
Widening
Long Term Capacity Concerns
The first build alternative is alternative I‐1. It is a conventional diamond that would complete the existing half diamond by adding ramps to the east side of IL 47 thus providing new access to and from the east. Because traffic signals are not warranted within 5 years of construction, intersections would be controlled by stop signs in the short term and traffic signals would later be installed for the long term. This alternative requires widening of the existing IL 47 bridge over I‐88. There are long term capacity concerns with this alternative.
20
CONVENTIONAL DIAMONDWITH ROUNDABOUTS
I-2
Operational Concerns

Widening
Higher Wetland Impact
The second build alternative is alternative I‐2. It is a conventional diamond, just like the previous alternative, but with roundabout intersections instead of conventional intersections. No traffic signals would be required with this alternative. There are operational concerns with this interchange type. This alternative would also result in the need for bridge widening. The footprint of this interchange results in higher wetland impacts.
21
DIVERGING DIAMOND (DDI) I-3
Higher Capacity than
Conventional Diamond
Requires Additional Bridge
Requires More Land Acquisition
Higher Wetland Impact
The third build alternative is alternative I‐3. It is a Diverging Diamond Interchange (DDI). A DDI is similar to a conventional diamond with traffic signals, except the Illinois Route 47 travel lanes cross each other twice, once on each side of the I‐88. The DDI provides more capacity than a conventional diamond. Traffic signals would be required for implementation. This alternative would require an additional IL 47 over I‐88 bridge to be constructed. This alternative requires more land acquisition and has a higher wetland impact.
22
PARTIAL CLOVERLEAF I-4
Stop Signs Short Term
Traffic Signals Long Term
Northeast Loop Ramp to Handle
High Traffic Volumes
No Additional Bridges or Bridge
Widening Required
The fourth and final build alternative is alternative I‐4. It is a partial cloverleaf (parclo) with a loop ramp in the northeast quadrant. This alternative is similar to the conventional diamond with traffic signals but with the addition of a loop ramp. This parclo is uniquely configured to handle high northbound to westbound left turn volumes. Stop signs would be implemented in the short term with traffic signals planned for the long term. This alternative would not require an additional IL 47 over I‐88 bridge nor would it require any bridge widening.
