LaSalle Drive Reconfiguration
Chicago Department of Transportation – Division of Engineering
The proposed improvement begins just east of the Clark Street Intersection and continues east to the northbound Lake Shore Drive entrance/exit ramps, consisting of traffic signal modernizations, roadway reconstruction, new ramp construction, intersection realignment with lane re-channelization, pedestrian underpass enhancements, a landscaped median along LaSalle Drive, as well as ornamental lighting. The main objective of the project was to reconfigure the intersection of LaSalle Drive with Local Lake Shore Drive and the southbound Lake Shore Drive exit ramps. The existing exit ramp from southbound Lake Shore Drive to LaSalle Drive separates a large triangular shaped piece of parkland from the main park. The proposed configuration will result in an overall reduction in the size of the intersection, and construction of a new ramp closer to the intersection will create a net gain in parkland or green space.
The decks of the two pedestrian underpasses along LaSalle Drive will be reconstructed and the structures enhanced with new LED lighting and skylights. Pedestrian accommodations were further improved by streamlining the travel path from the park to the beach, reducing the number of crossings from four to two. The engineering services include the preparation of a Phase I Project Development Report, which included field survey, geometric studies, Intersection Design Studies, crash analysis, a Location Drainage Study, Type, Size and Location Drawings, and two Bridge Condition Reports (pedestrian underpasses). In addition, Civiltech was responsible for the completion of separate reports for the parkland impacts (Section 4(f)) and historic preservation (Section 106) involvement as the project is contained entirely within historic Lincoln Park. Phase II Engineering services included the preparation of contract documents, specifications, and cost estimates. This project was closely coordinated with the Illinois Historic Preservation Agency (IHPA), Chicago Park District, the City’s Department of Environment and Department of Water Management, the Friends of the Park, and neighborhood interest groups. Construction began Summer 2010.

The goal of the project is to “Redefine the Drive”; that is to achieve a new balance between the needs of park and roadway by developing visionary improvements that will forever enhance this portion of Chicago’s iconic lakefront.
