SR 31 Dew Drop Inn Bridge

Owner: PennDOT District 9-0 Project Description:

This project, completed by Keller Engineers’ Transportation Division, replaced the structure carrying SR 31 over the Raystown Branch of the Juniata River, near the intersection of Diehl Road (T-402). The existing structure, built in 1931 was an 87’, two-span concrete t-beam bridge. Preliminary/Final Design and Construction Services for this bridge replacement project used an 86’-10” span P/S concrete PA bulb tee beam superstructure on concrete abutments. The overall project included 1,715’ of approach roadway improvements including straightening of the alignment to eliminate existing sight distance issues. Staged, partial width construction was utilized allowing improved alignment for this project.

The purpose of this project was to replace the structurally deficient bride and provide safe and efficient travel.
