Limits are 54' to the west and 57' to the east of the center of the bridge.
Corrugated metal pipe culverts are corroding throughout the state. The Department has over 200 bridge-length corrugated metal pipe culvert locations, most of which are at or beyond their expected 30-year service life. This project is one location of the 28 locations included in the current Design-Build contract and it will help the Department meet its performance measures related to number of bridges in fair or poor condition.
The scope of the proposed project is to replace the existing pipes with two 48-inch diameter circular reinforced concrete pipes placed on the outer sides of a 72-inch diameter reinforced concrete pipe. The pipes are 56 feet in length with sacked concrete riprap installed at the culvert inlet and outlet openings and along the steepest adjacent embankments. Stone riprap aprons will be placed outside of the culvert openings along the bottom of the channel to control stream erosion during flood flows.
Design phase to be completed by October 2018.
Construction to start early 2019 and will be completed in approximately 28 days.
This pipe replacement is part of a larger Design-Build project consisting of multiple locations.
