I-55 at Lake Shore Drive

Chicago, Illinois

The Illinois Department of Transportation is undertaking the reconstruction of the interchange of I-55 (the Stevenson Expressway) at Lake Shore Drive (US Route 41) in the City of Chicago. At its eastern terminus, I-55 links into Lake Shore Drive via several ramps and bridges. This urban expressway, neighbor to McCormick Place and Soldier Field, connects the neighborhoods and the lakefront from the south to the Central Business District and the Loop to the north. The project limits along I-55 include the structure and approach roadways extending from approximately Prairie Avenue spanning over Martin Luther King Jr. Drive and the Illinois Central (IC) Railroad/METRA Electric tracks to Lake Shore Drive.

The improvement limits along Lake Shore Drive extend from approximately 23rd Street near Soldier Field to approximately 1000’ north of 31st Street. The total project length including the six bridge structures is approximately 1.1 miles.

IDOT contracted with Kenny Construction for the outbound ramps and IHC for the inbound ramps of the complex interchange. Both companies selected DLZ to provide construction layout and surveying assistance for the project. Our team used advanced laser scanning to ensure project tolerances for within acceptable ranges.
