Route 30 over West Branch of Conococheague Creek Bridge Rehabilitation Project

County: Franklin
Municipality: Peters Township
State Route: SR 0030-158
Local Name: Route 30 (Lincoln Highway) over West Branch of the Conococheague Creek
Project Type: Bridge Rehabilitation
MPMS Number: 117144
Proposed Construction Start: June 2027
Proposed Construction End: September 2027
Last Updated: April 2025

The Route 0030 Section 158 bridge preservation project is located along Route 30 (Lincoln Highway) over West Branch of the Conococheague Creek in Peters Township, Franklin County, approximately 12 miles west of Chambersburg. The purpose of this project is to preserve the bridge and provide continued safe and efficient crossing of Route 30 over West Branch of the Conococheague Creek.

The existing structure was built in 1960 and is a two-span composite prestressed concrete beam bridge supported on full-height concrete abutments at a 65-degree skew.  A wall pier in the center of the bridge is located in the West Branch of the Conococheague Creek.  The bridge length is 118’-3”, measured center-center of bearings from abutment to abutment.

The project involves the replacement of the expansion joints at the abutments and pier, substructure spall repairs and repair of a scour hole at an abutment.  A temporary stream diversion (cofferdam setup) will be constructed to complete the scour repairs.  The overall geometry of the bridge will not be affected by the repairs. 

This section of Lincoln Highway has an average daily traffic volume of 6012 vehicles per day (vpd).

The bridge will remain open to traffic during construction with limited shoulder closures during the day to install scour protection under the bridge and repair the substructures.  Half width bridge closures will occur at night to allow for the joint replacement using an alternating traffic pattern in one lane with flaggers.

There are no overhead utilities present at the site.

The project is currently in design, and construction work is anticipated to begin in Spring 2027 and last approximately 3 months.

The purpose of the plans display is to introduce the project and solicit public input, questions, or concerns regarding the project.​
