Kennedy Expressway (I-90/I-94) Bridge Rehabilitation Project

HBM Engineering Group led Phase II Engineering Services for the Northbound & Reversible I-90/94 Mainline Bridge Deck Overlay & Joint Repair and Roadway Pavement Patching Project. This transformative initiative, in IDOT Region 1, District One, aimed at rehabilitating critical bridges, ensuring their longevity and functionality.

I-90/I-94 Inbound (SB) – 23 Bridge
I-90/I-94 Reversible  – 21 Bridge
I-90/I-94 Outbound (NB) – 19 Bridge

Project efforts totaling approximately $150 million will include:

  • Repairs to 36 bridges between Ohio Street and the I-90/I-94 split
  • Pavement patching
  • Overhead sign-structure replacements
  • LED lighting upgrades
  • Installing new signage
  • Structural painting
  • Rehabilitation of the Reversible Lane Access Control (REVLAC) system, which supports traffic flow changes
