Division Street over I-57 Interchange Reconstruction

Manteno, Illinois

  • Phase II engineering services for replacing the structure carrying County Highway 9 (Division Street) over I-57 as well as reconstructing the interchange ramps, County Highway 9 and an existing frontage road.

  • The design includes additional through lanes, turn lanes, median and a shared-use path.

  • Interchange ramps and the frontage road will be realigned to accommodate proposed improvements.

  • A 3D model is being completed using Bentley OpenRoads.

  • The following structures are included in this project:

    • S.N. 046-0058: County Highway 9 over I-57

    • S.N. 046-8802: retaining wall

  • A hydraulic analysis was performed to determine if the existing culvert crossing under I-57 has sufficient capacity.

  • Approximately 1.75 miles of I-57 will be rehabilitated/resurfaced and inside shoulders will be widened/reconstructed as part of the proposed improvements.
