Illinois Department of Transportation

The new bridge is the longest span over the Union Pacific Railroad.

Overview

Horner & Shifrin prepared a Phase I location study and Phase II construction plans for the replacement of the IL 3 structure over the Union Pacific Railroad (UPRR) and Prairie DuPont Canal north of the Village of Dupo, IL. The new structure is a four span, 990ft long bridge. This is the longest span, over the UPRR and also spans over a levee, which is 330ft long.

Horner & Shifrin’s tasks during Phase I consisted of studying alignment and structure alternatives and preparing a Phase I project report for design approval, including an intersection design study, location drainage study, crash analysis, traffic management analysis, bridge condition report, bridge type study, and type, size, and location plan. Phase II consisted of preparing the plans, specifications, and estimates for the construction of the replacement structure.
