Bridge 3-923 is located southeast of the town of Milford in New Sussex County, Delaware. The project limits are approximately 200 feet Southwest and 200 feet Northeast from the center of the bridge.
Corrugated metal pipe culverts are corroding throughout the state. The Department has over 200 bridge-length corrugated metal pipe culvert locations, most of which are at or beyond their expected 30-year service life. This project is one location of the 28 locations included in the current Design-Build contract and it will help the Department meet its performance measures related to number of bridges in fair or poor condition.
The scope of the proposed project is to replace the existing corrugated steel pipes with three 66-inch diameter circular reinforced concrete pipes. The proposed pipes are 72 feet in length. Riprap will be placed on the embankments at all pipe inlets and outlets.
Work also includes the replacement of approximately 200 feet of guardrail on both sides of the roadway. Pipe replacement will be performed under a full road closure with a posted detour.
Design work anticipated to be completed by Sping 2019.
Construction work anticipated to be completed by Summer 2019.
This pipe replacement is part of a larger Design-Build project consisting of multiple locations.
