SR 374 Bridge Preservation Project

County: Susquehanna
Project Type: Bridge Preservation
Start Month: Fall 2024
End Month: Spring 2025
Last Updated: July 14, 2023

The purpose of the project is to replace the existing structure that carries two lanes of traffic on Route 374 over the Outlet of Lowe Lake in Herrick Township, Susquehanna County.  The existing structure consists of two 36" diameter corrugated plastic pipes that have been placed as part of an emergency replacement to a steel I-beam bridge. This project also includes approximately 50' of roadway approach work along Route 374 to allow for smooth transitions and bridge construction while a detour is in place.

The proposed alternative is a precast reinforced concrete box culvert.  This alternative matches the existing stream width in the project area and provides a hydraulic opening sufficient to pass PennDOT and DEP design storms without increasing 100-year water surface elevations.  A bridge roadway width of 24 feet is proposed (two 10-foot lanes with 2-foot shoulders).

The roadway at the bridge site will be closed to all traffic and detoured during construction and is expected to be closed for approximately one month. 

The project is currently in design and is planned to be let in September 2024. Construction work is anticipated to take place in the Spring of 2025.
