IL 1 & CSX Railroad - Milford, IL

The primary purpose of the project is to improve safety and roadway operations by replacing the existing roadway/railroad grade separation for Illinois Route 1 roadway and CSX railroad just north of Milford. The project involves removing the existing single span thru girder bridge (SN 038-0024) and replacing it with a structure which carries IL 1 over the CSX Railroad just west of the existing viaduct. This bridge has been determined to be eligible for listing on the National Register of Historical Places.

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.

 

Realigning IL 1 with a bridge over the CSX Railroad just north of Milford

Project Scope:

  • Realigning IL 1 with a new 44’ wide roadway bridge over the CSX Railroad approximately 200’ northwest of the existing bridge.  Work includes:
    • Relocating the County Highway 25 (CH 25) intersection to the north.
    • Removing, consolidating, or relocating entrances.
    • Constructing ditches and other highway drainage improvements.
  • Maintaining traffic under the existing bridge until the new bridge is built.
  • Removing the existing bridge over IL 1 and filling the underpass.

Project Purpose:

  • To address the condition of the bridge.
  • To address IL 1 clearances and flooding issues.

Project Need:

  • Deteriorated condition of the bridge carrying the CSX Railroad over IL 1.
  • Sag vertical clearance under the bridge (13’-8”) does not meet the minimum vertical clearance (14’) for bridges to remain in place. 
  • Oversize vehicles hitting the bottom of the bridge
  • Occasional road closures due to flooding under the bridge.
  • Narrow roadway under the bridge.
