IL 13/127 (Murphysboro to Pinckneyville) Project Study

The proposed project involves the upgrading of approximately 23 miles of existing Illinois Route 13/Illinois Route 127 from two lanes to four lanes beginning at the Ava Road intersection north of Murphysboro in Jackson County and ending on Illinois 127 just north of Pinckneyville in Perry County. Included in the project are an eastern bypass of the Village of Vergennes, an interchange at Illinois Route 152 and a western bypass of the City of Pinckneyville, with an interchange at Illinois 154. The proposed project will provide a safe and efficient facility while addressing system continuity and regional access by working towards closing a significant gap in the National Highway System of four-lane highways between major population centers in southern Illinois and the St. Louis metropolitan area.

The need for the proposed project is based on several factors. The improvement is intended to address the need for highway system continuity and regional access, existing roadway deficiencies, traffic safety, traffic flow and capacity deficiencies in downtown Pinckneyville, and local and regional economic development. This study is a federally-funded study mandated by the 1998 Transportation Equity Act for the 21st Century (TEA-21).

Note: IDOT projects typically have three distinct phases. Phase I (or the project Study) consists of developing the project scope, environmental studies and preliminary design of a project. Phase II (Design) consists of refining the design to develop contract plans and land acquisition. Phase III (Construction) consists of the actual construction of the project.


Corridor Protection is allowed under Section 4-510 of the Illinois Highway Code (605 ILCS 5/4-510). Since the public meeting, a final Corridor Protection Map has been filed in the Perry County Recorder’s Office. This filing provides a means of protecting the right of way needed for future improvements.

Corridor protection applies to the portion of the project known as the West Bypass. More particularly, it begins a short distance south of Chicken Creek on existing Illinois Route 13/127; it proceeds in a northerly direction around the west side of Pinckneyville to an ending point on existing Illinois Route 13/127 a short distance north of Quail Ridge Road.

The Corridor Protection Map indicates the approximate right-of-way limits that are anticipated to be needed for the corridor. Property owners planning to make an improvement within the corridor should contact IDOT by registered mail no less than sixty (60) days prior to starting construction. The Department will decide within forty-five (45) days whether or not to acquire the additional right of way.

The project's Environmental Assessment (EA), containing the final analyses and reporting on the preferred alternatives, was approved by the Federal Highway Administration (FHWA) on September 14, 2007. The FHWA issued a Finding of No Significant Impact (FONSI) for this project on December 16, 2008. These documents may be viewed by clicking below:

Pinckneyville Area Citizens Advisory Council

In 2004 the IDOT District 9 Office decided to assemble an Illinois 13/127 Pinckneyville Area Citizens Advisory Council to gain insight into the issues and values of the public in the Pinckneyville area in hopes of better understanding what highway option would best serve the community.  The intent for forming an Illinois 13/127 Pinckneyville Area Citizens Advisory Council was to provide an effective means for public discussion on the five alternate alignments under consideration in the Pinckneyville area. Sixteen council members plus four technical advisors served on the assembled group.View the Advisory Council’s Final Report (606k pdf)

Any further questions can be addressed by calling or visiting the IDOT Region 5, District 9 Headquarters at 2801 West Murphysboro Rd. on the west edge of Carbondale at (618) 549-2171.

IDOT is currently at the early stages of Phase I for this project. This site will be updated periodically as the project progresses. The Illinois Department of Transportation (IDOT) wishes to thank you for your support and patience.
