Infrastructure Engineering, Inc. 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, we provided the City of Peoria, 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 Avenue, was an aging structure along an arterial roadway that was constructed in 1942 and received a maintenance renovation in 2001.
We not only led the design team, but were the intermediary between the City of Peoria, the Illinois Department of Transportation (IDOT), Utility Owners, and the Federal Highway Administration (FHWA). IEI provided the Civil Engineering services for Phase I, 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, as well as the Structural Phase I and Phase II Engineering services. This included the Bridge Condition Report (BCR), the type, size and location (TS&L), bridge and retaining wall design, as well as project 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.
