Expressway Viaduct Rehabilitation

City of Chicago, IL

Project Summary

Every day over 300,000 vehicles use the Kennedy and Dan Ryan Expressways, the busiest in Illinois. The viaducts that span these routes through the heart of Chicago are vital to the city's infrastructure. When IDOT designed a program to address structural deficiencies, TranSystems became the key to efficient management and administration of the 22 individual bridge projects, let and supervised by CDOT. For this viaduct with an extremely deteriorated bridge deck and load-deficient steel beams, TranSystems supervised replacement of the bridge deck, parapet walls, sidewalks, railings and bearings.

Project Highlights

  • Provided resident engineering services for five of the bridges.
  • Acted as the single point of contact for state and local public agencies, private utility companies, project designers and resident engineers.
  • Development of a written manual of standard operating procedures for the program.
