250 feet north and south of the bridge
There is significant corrosion at the waterline with 100% section loss at several locations throughout the pipes. The existing pipes are structurally deficient and were selected by the Pontis Bridge Management System for work. This bridge is currently ranked 71st on the 2013 DelDOT Bridge Deficiency List.
This project involves the replacement of three existing corrugated metal pipes with a precast concrete frame or culvert. Additional work includes minor reconstruction of the approach roadway and sidewalk, installation of guardrail as needed, and placement of riprap in the stream to prevent scour. The work will be performed under a full road closure with detour.
Design work completed June 2016.
Construction work to be completed by early summer 2017.
A temporary pedestrian bypass will be created due to closure of sidewalk during the construction.
