BR 2-118A on K118 Coon Den Road over Nanticoke River
Approximately 250 feet east and 250 feet west of the bridge
The existing pipes at the bridge are structurally deficient and were selected by the Pontis Bridge Management System for work. There is corrosion at the waterline with 100% section loss at some locations. Replacement of this bridge will help the Department meet its performance measure for percentage of bridges in poor condition. This bridge is ranked 65th on the 2015 DelDOT Bridge Deficiency List (out of 1625 total bridges).
This work involves the replacement of the existing corrugated metal pipes with a precast concrete box culvert. Additional work includes the reconstruction of the approach roadway, installation of guardrail as needed, and placement of riprap in the stream for scour protection. Work will be performed under a full road closure with detour.
Design completed May 2018.
Construction work to be completed January 2019.
The "clear zone" concept will be utilized here due to access roads and driveways in close proximity to the bridge.
