Illinois Route 13 - Carbondale to Carterville
Proposed Traffic and Roadway Network Improvements

Project Description

The Illinois Department of Transportation is in initial planning stages for a project to add a third lane in each direction on Illinois Route 13 from east of Giant City Road in Carbondale to west of Shawnee Trail in Carterville.   Intersection improvements will be made to Veterans Parkway, Reed Station Road, Spillway Road, Cambria Road and Campground Road.  The project is not currently funded and no anticipated construction date is known.

Today, traffic levels range between 30,000 to 35,000 vehicles per day on the 4-lane roadway system that nears or exceeds acceptable capacity levels. This traffic, coupled with closely spaced intersections has compromised safety and traffic mobility and efficiency. In a six-year period from 2007 to 2012, there were a total of 324 crashes resulting in two deaths and 12 Type A injuries. A Type A injury is defined as any injury, other than a fatal injury, which prevents the injured person from walking, driving, or normally continuing the activities he/she was capable of performing before the injury occurred.

The following data sheets show accident information, peak hour turning volumes and ADT’s on each leg at the intersections:

Existing Spillway

As part of the planning for the project a process called Contest Sensitive Solution (CSS) will be used.  CSS ensures effective identification and understanding of the concerns and values of all stakeholders (i.e., person and entities that have a stake in the outcome of a highway project).  The purpose of the stakeholder involvement process is to promote a proactive and responsive CSS approach that seeks the input of the full range of concerned stakeholders early and often, and that provides for appropriate consideration of stakeholder input at key points in the project decision-making process (e.g., project purpose, range of alternative, selection of a preferred alternative). A project study group has been formed with representatives throughout the project limits and meetings are being held throughout the planning stage.

Thoughout the beginning of the 2014 several stakeholder meetings were held to present alternatives for the intersections within the project limits as well as possible bike accomodations.  Information from the meetings was collected and presented to the Project Study Group.  The Project Study Group reviewed the comments and determined which alternatives should proceed for further study.  A public meeting was held at John A. Logan College on May 28, 2014 to present those chosen alternatives and to receive comments from the public.  The following exhibits were presented.  Comments received from the meeting will be used in conjunction with environmental studies and engineering studies to choose the preferred intersection type at each intersection.  The preferred alternates will be presented at a meeting in the late summer of 2014.

Reed Station Road
Two alternates were presented for Reed Station Road:
(a)   Dual left turn lanes constructed for the eastbound to northbound movement, the southbound to westbound right turn will be converted to a “free flow” movement and an additional through lane will be constructed for IL 13 eastbound and westbound.
(b)   In addition to the new turn lanes and through lanes described above, a new frontage road would be constructed in the southwest quadrant of the intersection and Sweets Drive would be limited to right in/right out.

Spillway Road
Two alternates were presented for Spillway Road:
(a)   No change on IL 13 except for the additional through lane in each direction.
(b)   In addition to the new through lanes, a ‘Slip ramp” would be constructed east of Spillway Road to allow westbound traffic to access the north leg of Spillway Road.

Cambria Road/The Haven Entrance
Four alternates were presents for the Cambria Road/The Haven Entrance:
(a)   Signalized “T” intersection with The Haven entrance limited to right in/right out.

(b)   Unsignalized with left turns from IL 13 allowed but lefts originating from Cambria Road and The Haven accommodated via a right turn and a “U” turn on IL 13.

(c)    Fully signalized crossroad intersection with all movements in and out of Cambria Road and the Haven having a dedicated signal phase.

(d)   Unsignalized with left turns from IL 13 allowed but lefts originating from Cambria Road accommodated via a “slip ramp” located east of Spillway Road to allow them to turn around at a signalized intersection (Spillway). This is the same alternate shown in Spillway Road section.

Campground Road
Two alternates were presented for Campground Road:
(a)   Signalized “T” intersection.

(b)   Existing access closed and campground traffic routed to IL 13 via a frontage road to the Greenbrier Rd./IL 13 intersection.
Note: For both option (a) and (b) above the north boat launch area will be permanently closed.  As mitigation for the loss of the northern boat launch, improvements will be made to other existing launches within the refuge

Bike Accomodations

Three alternates were presented for Bike Accommodations:
(a)   A 10’ wide asphalt shoulder will be constructed throughout and will be marked for use by cyclists.  The path will tie into existing frontage roads where appropriate.

(b)   A 10’ wide side path will be constructed off of the roadway for cyclists.  Across Crab Orchard Lake the path will be adjacent to the roadway but a barrier will be constructed to separate bike and vehicle traffic.

(c)   Bike traffic will be accommodated through a combination of a separate side path and a bike lane on the shoulder.
Note: In order for a separate side path to be included in the project IDOT policy requires that another agency accept maintenance of the path.  If no other agency will accept maintenance a side path will not be constructed and bike traffic will be accommodated on the shoulder of IL 13.

The preliminary project cost estimate is $39.7 million.
