Above and under the bridge
The timber sheeting is failing and the concrete culvert has a few minor spalls in need of repair. Routine structure maintenance extends the life of bridges. The roadway across the overflow area is also in poor condition.Bridge 1-400 is in fair condition (NBI=5), is ranked 13th on the 2016 DelDOT Bridge Deficiency List, and was selected for work through the Bridge Management System.
This project involves the replacement of the existing timber sheetpile wingwalls with new steel sheetpiles. Additional work includes patching minor concrete spalls on the culvert, resurfacing the roadway through the overflow area, and replacing the guardrail.
Design work to be completed no later than Spring 2018
