HEI was selected by Peoria County to provide Phase III engineering services for this $1.5M federally funded bridge replacement project. The project featured the removal of a 5-span steel girder bridge and construction of a 124’ single span steel girder (54” deep web) structure with a reinforced concrete deck and cast-in-place PCC parapets. 

The project included demolition of the existing structure, new substructure including 2 abutments and steel H-piles, concrete approach pavements, embankment widening, riprap, guardrail, and articulated block revetment mat for a recreational trail under the structure. 



HEI provided the Resident Technician, construction inspectors, and materials testers to perform daily construction inspection, diary entries, traffic control inspections, erosion control inspections, daily quantity and materials documentation, materials testing including concrete testing, nuclear density testing, and DCP testing. Due to the project being funded with federal funds, the HEI Resident Technician routinely coordinated with IDOT.
