IDOT is proposing to upgrade a section of Illinois Route 97 (IL 97) northwest of Springfield.  The facility is currently a two-lane rural highway west of Koke Mill Road and continues as a four-lane urban section approaching Veterans Parkway.  This portion of IL 97 primarily serves commuters that live in surrounding northwestern communities but work in the Springfield Metropolitan area.  IL 97 also represents a primary route for tourists traveling to the New Salem Village Historic Site which is located approximately 14 miles north of the project’s western terminus and is one of the most visited historic sites in all of Illinois. 

The proposed upgrade consists of constructing and rehabilitating approximately 5.5 miles of IL 97 from Veteran’s Parkway to IL 97/125 in two sections, with two bridge replacements, geometric improvements, and drainage upgrades.  This project will provide a new expressway for a smooth and safe ride for motorists and will support future investment in the region.

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.

OVERVIEW

Project Description

Illinois Route 97 is currently a 2-lane State highway that extends from Veteran’s Parkway in Springfield to U.S. Highway 150 near Galesburg.  The 5.5 mile, east-west section from Veterans Parkway to the IL 125/97 junction west of Springfield is proposed to be upgraded to a partial access controlled, 4-lane expressway.

The proposed improvement involves an alignment shift to the north to allow for a bypass around the town of Bradfordton, replacement of the Prairie Creek and Sangamon Valley Trail bridge structures, and signalized intersections at Bradfordton Road and at the Illinois Route 125/97 junction.

The primary purpose in upgrading the Illinois Route 97 facility is to reduce accident rates, increase capacity to meet both current and projected traffic demands, and avert flooding at the Prairie Creek crossing.

Corridor Highlights

The project begins immediately west of Veteran’s Parkway and extends west along Illinois Route 97. All business and residential access from IL 97 will be replaced. New intersections will be constructed at Winch Lane and Emporia Avenue. Five lanes of new pavement with a center turn lane will be added between Winch Lane and Koke Mill Road.

The existing bridge over IL 97 for the Sangamon Valley Trail will be removed and replaced with a new bridge as expeditiously as possible to minimize delays for trail users.

From Koke Mill Road to the west, the remainder of this project will consist of a 4-lane divided expressway. New intersections will be constructed at Koke Mill Road, Hazlett Road, Old Covered Bridge Lane & County Highway 46, and Farmington Cemetery Road.  Additional frontage roads and field access are included along the route to maintain access to property owners.

The existing IL 97 roadway will serve as a frontage road for businesses and residents between Old Covered Bridge Lane and Hazlett Road.  The existing intersection at Bradfordton Road will be widened with a two-way stop-controlled intersection for east-west traffic. 

New 4-way signalized intersections with turn lanes will be constructed at Bradfordton Road and at the junction of IL 125 & IL 97.  A free-flowing northbound ramp will be added for traffic proceeding north on IL 97.

The existing bridge and pavement at Prairie Creek will be removed and replaced a couple of hundred feet to the south and about a quarter mile section of Prairie Creek, to the west, will be re-aligned.

The project terminates near Smith Road and tapers back to the existing two-lane highway and IL 125 continues to the west.

Schedule

This project is currently identified in IDOT’s Fiscal Year 2021 – 2026 Multi-Year Program, which is subject to the availability of funds and is anticipated to be constructed under two contracts.
