Expedited Design Improves Safety of Dangerous Chicago Intersection
Since 1985, the intersection of Cicero Avenue (Route 50) at 127th Street and I-294 (Tri-State Tollway) in Alsip has consistently ranked among the top 10 most dangerous in the state by the Illinois Department of Transportation (IDOT). Improving this roadway was included as a high priority project in the Governor's Illinois FIRST program.
The project included the reconstruction and widening of the Cicero and 127th Street intersection from five to nine lanes, the rehabilitation of three bridges over the Tri-State Tollway, construction of a new flyover bridge, and the construction of three new tollway ramps.
Illinois DOT retained Stanley Consultants to design the highly visible project upgrade with an extremely accelerated schedule. Preliminary drawings were delivered for review just three months after notice-to-proceed. Advance construction work began just seven months after project authorization. Extensive coordination between Illinois DOT, ISHTA, and the Village of Alsip was maintained through the design project.
