200 feet north and south of the bridge
There is significant corrosion at and above 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 currently has a 72.9 sufficiency rating.
This project involves the replacement of one existing corrugated metal arch-pipes with either one precast concrete pipe or a precast concrete box culvert. 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 likely be performed under a full road closure with detour.
Design work to be completed no later than June, 2016
Construction work to be completed at the end of March, 2017
