Bridge 1-454 is located southeast of the town of Townsend in New Castle County, Delaware. The project limits are approximately 200 feet East and 200 feet West 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 three circular 84-inch diameter 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 stream bed upstream and downstream. Pipe replacement will be performed under a full road closure with a posted detour.
Design work anticipated to be completed by Spring 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.
This work will occur within the boundary of the Eagle’s Nest Wildlife Area (Ellingsworth Tract), but will not adversely affect any of the activities, features, or attributes of the Wildlife Area.
