INFORMATION

Project Limits:

230 feet north and south of bridge

Project Need

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 was ranked 77th on the 2010 DelDOT Bridge Deficiency List.

Project Overview:

This project involves the replacement of the existing corrugated metal pipes with precast, prestressed concrete beams on shallow abutments. Additional work includes minor reconstruction of the approach roadway, 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.
