OMEGA provided construction engineering services for the Illinois Department of Transportation’s $45 million Dan Ryan Elevated Bridge Structure Rehabilitation Project.

Project Scope

The two-year project involved:

  • Milling and hydro-scarification of the existing bridge decks
  • Overlaying the bridge deck with microsilica concrete

 

The Dan Ryan Expressway carries more than 300,000 vehicles a day, making it the busiest expressway in Chicago. During construction, three lanes of traffic always remained open in each direction. The project was completed one month ahead of schedule and is expected to extend the life of the elevated bridge structures by approximately 25 years.
