111th Street Widening and Resurfacing
Roadway width and configuration continuity along with new bicycle/pedestrian facilities were desired by IDOT to improve a section of 111th Street. Once complete, the corridor will be transformed from four to five lanes and provide much-needed congestion relief.
HLR performed preliminary engineering services for the 0.7-mile-long project. Significant coordination with the Villages of Worth and Palos Hills was required to incorporate design requests. Our team also performed drainage studies to identify deficiencies such as insufficient inlet capacity and limited stormwater detention areas.
HLR led a public information meeting and prepared all meeting exhibits and brochures. During the Phase I process, HLR also incorporated IDOT’s “Complete Streets” policy which involves significant changes to bike and pedestrian requirements.
