Bridge 3-335 is located north of the town of Delmar in Sussex County, Delaware. The project limits are approximately 400 feet West and 400 feet East 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 pipes with two 72-inch diameter circular reinforced concrete pipes that are 64 feet in length with riprap aprons installed at the culvert openings both upstream and downstream. Pipe replacement will be performed under a full road closure with a posted detour.
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.
