Jackson & Perry Counties - IL 13 & 127 (Murphysboro to Pinckneyville)
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.
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.
