Division Street over I-57 Interchange Reconstruction

Manteno, Illinois

  • V3 is providing Phase II engineering services for the reconstruction of the I-57 interchange at County Highway 9 (Division Street) in Manteno, Illinois. The improvements are proposed to address ongoing regional growth and existing geometric and operational deficiencies.
  • The interchange will be modified from a conventional, partially signalized diamond to a tight diamond configuration with full signalization.
  • Division Street at I-57 will be widened from a two-lane rural roadway to a four-lane urban section with additional channelization and a 10-foot wide shared use path along the north side of the roadway.
  • Approximately two miles of I-57 mainline pavement will be rehabilitated/resurfaced and the inside shoulders widened/reconstructed as part of the proposed improvements.
  • The existing four-span structure over I-57 will be reconstructed as a two-span structure with a total length of 230 feet and an out-to-out width of 96 feet. The deck will be supported on 45-inch deep PPC beams with integral abutments driven down to bedrock. The bridge will also include a variety of aesthetic enhancements at the request of local agencies.
  • The project will also include an approximately 500-foot long, 15-foot high solder pile retaining wall along the north side of Division Street (directly west of I-57).
  • A detailed hydraulic analysis is being performed to determine if the existing culvert crossing under I-57 has sufficient capacity.
  • A 3D model of the proposed improvements is being developed utilizing the latest version of Bentley’s OpenRoad Designer software.
