Bridge Removal and Replacement

Phase III engineering services were required to provide construction inspection for the removal and replacement of the structure that carries US 52/IL 64 over the Mississippi River between Savanna, Illinois and Sabula, Iowa. The new bridge is a tied-arch design, relocated to the south of the existing structure. The contract included reconstruction of 1,400 feet of US 52 causeway in Iowa. Reconstruction of the causeway involved placing new embankment, riprap, and removing and replacing guardrail. Also included in this project was the reconstruction of 2,400 feet of IL 84 roadway in Illinois, as well as 1,565 feet of retaining wall along IL 84. The IL 84 reconstruction entailed removing and replacing the guardrail, curb and gutter, sidewalk and driveway entrances. The project included inspection and documentation of pay quantities, on-site material testing, material quality assurance testing, and construction staking layout. IMEG assisted the resident engineer with all documentation on the project.
