Approximately 200 feet north and south of the bridge along Lake Front Drive.
This bridge consists of one corrugated metal pipe arch. There is significant corrosion at the waterline with 100% section loss at several locations throughout the pipe arch. The existing pipe arch is structurally deficient and was selected by the Pontis Bridge Management System for work. It has a sufficiency rating of 62.8 and was ranked 69th in the 2014 DelDOT Bridge Deficiency List.
This project involves sliding two 5’-6” diameter steel-reinforced high density polyethylene pipes into the existing corrugated metal pipe. It will allow Lake Front Drive to remain open to traffic, and will require placing riprap for scour protection downstream. Reconstructing the approaches will be performed as necessary. Work will be performed under a partial road closure.
Design work completed no later than May 2016
Construction work to be completed in the winter of 2017.
This project requires extensive coordination with the railroad as well as utility companies.
