Bridge 3-564 is located south of the town of Gumboro in Sussex County, Delaware. The project limits are approximately 400 feet North and 400 feet South 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 round steel pipes with three circular 60-inchdiameter reinforced concrete pipes. The proposed pipes are 64 feet in length with riprap aprons installed at the culvert inlet and outlet openings, extending into the streambed upstream and downstream.
Design work anticipated to be completed by August 2019.
Construction work anticipated to be completed by September 2019.
This pipe replacement is part of a larger Design-Build project consisting of multiple locations.
