PA Turnpike Milepost 123.3 to 125.8 - Mill and Pave
Milepost 125.8 TO 133.8 - Reconstruction and Widening

Project Overview

The Pennsylvania Turnpike Commission (PTC) is planning to mill and pave approximately 2.5 miles of the PA Turnpike (Milepost 123.3 to 125.8) and reconstruct approximately 8.0 miles of the PA Turnpike (Milepost 125.8 to 133.8) in Somerset and Bedford Counties. Reconstruction includes widening and curve flattening on the Turnpike mainline, the replacement of three overhead bridges (over the Turnpike) and two Turnpike mainline bridges, construction of a new access ramp bridge, and the rehabilitation of the Tunnel Road structure. Also included is the New Baltimore Slope Remediation project located from Milepost 127.9 (Tunnel Road) to Milepost 128.7 (0.3 miles West of Findley Street) in Allegheny Township, Somerset County. The full depth roadway reconstruction and widening begins at Milepost 125.8 (2.5 Miles East of the Allegheny Tunnel) in Allegheny Township, Somerset County and continues to Milepost 133.8 (1.4 Miles East of the Kegg Maintenance Facility) in Juniata Township, Bedford County. At the west end of the project, milling and bituminous resurfacing of the existing Turnpike mainline will start at Milepost 123.3 (East end of Allegheny Tunnel) and end at Milepost 125.8 (Start of full depth reconstruction). All work will occur within Allegheny Township and New Baltimore Borough in Somerset County and Juniata Township in Bedford County.

Full depth reconstruction of the Turnpike mainline will be completed in two construction contracts, one from Milepost 125.8 to Milepost 130.5 (Western Mainline) and one from Milepost 130.5 to Milepost 133.8 (Eastern Mainline). Upon completion of the projects, the Turnpike will be widened to 122 feet. It will consist of 6 travel lanes (3 westbound and 3 eastbound) with a 26-foot median, and 12-foot outside shoulders. The three overhead bridges have already been replaced and the New Baltimore Slope Remediation is complete.

Completed Construction Contracts:

  • Cider Road East Bridge Replacement (Juniata Township), Milepost 132.5 (Construction completed in 2012)
  • Cider Road West Bridge Replacement (Juniata Township), Milepost 130.9 (Construction completed in 2013)
  • Findley Street Bridge Replacement (New Baltimore Borough), Milepost 129.0 (Construction completed in 2014)
  • New Baltimore Slope Remediation project (Allegheny Township), Milepost 127.9 to 128.7 (Construction completed in 2017)

Two mainline bridges will be replaced as part of the western mainline reconstruction and widening project. The bridges are:

  • Mainline over S.R. 3012 (Juniata Township), Milepost 129.9
  • Mainline over the Raystown Branch of the Juniata River (Juniata Township) at Milepost 130.0

The structure carrying Tunnel Road under the Turnpike at Milepost 127.9 will be rehabilitated as part of the western mainline reconstruction and widening project. A new access ramp from the Eastbound Turnpike to Tunnel Road at Milepost 127.6 will also be constructed and includes a new bridge over Three Lick Run.

This project also involves constructing noise barriers along the westbound lanes at the town of New Baltimore as depicted in the noise report; constructing new stormwater facilities, retaining walls, culvert replacements and wetland / stream mitigation sites.
