IEI was awarded the American Council of Engineering Companies (ACEC-IL) Merit Award and the (ACEC-NY) Silver Award for MacArthur Bridge. As the prime firm on the project, IEI provided the City of Peoria (City) Phase I and Phase II engineering services for the replacement of the MacArthur Highway Bridge. The existing bridge structure, which spanned over Romeo B. Garrett A venue, was an aging structure along an arterial roadway that was constructed in 1942 and received a maintenance renovation in 2001.
IEI not only led the design team, but was the intermediary between the City (Client and Owner), Illinois Department of Transportation (IDOT), Utility Owners and the Federal Highway Administration (FHWA). We provided the Civil Engineering for Phase I Engineering services, which included a Traffic Study and an Intersection Design Study (IDS) to modify one of the adjacent intersections. With support of our architectural partner, we completed the section 106/Section 4(f) Documentation of Adverse Effects. We also provided Quality Assurance / Quality Control (QA/QC) of the Phase II Civil Engineering Documents. IEI also provided the Structural Phase I and Phase II Engineering services, which included the Bridge Condition Report (BCR), the type, size and location (TS&L) and the structural portion of the Construction Plans, Specifications and Cost Estimate (PS&E).
The existing bridge was a four-lane structure for vehicle traffic only. However pedestrian and bicycle traffic was regular on the MacArthur Highway. The project decreased the vehicle lanes to two and added a protected pedestrian sidewalk and a protected bicycle lane. This project has transformed adjacent empty lots to a park space with trees, pollinator gardens, bio-retention basins, sidewalks and pedestrian lighting, a decorative pedestrian bridge and art display space.
