Mileposts 12-14 Total Reconstruction

Traveling Construction Mileposts 12-14 Total Reconstruction

Total reconstruction and widening of the Pennsylvania Turnpike (I-76) to three lanes each direction from Milepost 12 to Milepost 14, Beaver County

Project Overview

This multi phase project involves the total reconstruction and widening of two miles of the Turnpike's east-west mainline (Interstate 76) between Milepost 12 and Milepost 14. Upon completion of this project the existing four-lane facility, will be upgraded to include six-twelve foot travel lanes, three (3) East bound and three (3) West bound, 12 foot shoulders and 10 foot medians in each direction. In order to accommodate the new six lane facility, four early action bridges including, two overhead Norfolk Southern railroad bridges will be replaced prior to the start of construction of the Turnpike mainline. To date (2020) all early action projects have been completed. Construction of the turnpike mainline and the bridges of the Beaver River are currently in final design.

Stage 1 - September 2013 - November 2017 - Three, separate Early Action Bridge Replacement Projects

Stage 2 - Spring 2023 - Fall 2027 - Total Reconstruction MP 12-14 and Replacement of Bridge WB-206 Over the Beaver River

Project Cost - To Be Determined.

This project, located in North Sewickley Township, Homewood Borough and Big Beaver Borough in Beaver County, involves the complete replacement of the mainline bridge over the Beaver River (WB-211, MP T13.21) The mainline will be shifted to the north to accommodate traffic during construction and to avoid environmental and utility issues to the south. The existing interchange will be reconfigured into a conventional interchange with SR 0018. The new roadway will be constructed to accommodate six lanes of traffic. The approximate limits of construction range from Milepost 12 to Milepost 14.

This project also involves the complete replacement of three overhead structures (WB-206, WB-207, WB-208), a mainline bridge (WB-209) over SR 0018, a culvert (WB-212) extension over Thompson Run and a new retaining wall within the reconfigured interchange.

Two of the overhead structures (WB-207, WB-208) carry Norfolk Southern Railroad and have been replaced under an early action contract, completed in November of 2015. The replacement structures are two span, steel, thru-girder bridges.

A temporary bridge was installed between late 2013 and Mid 2014 to replace bridge WB-210A, Exit 13 ramps over SR 0018. The temporary bridge was required due to the poor condition of the existing structure and the lack of clearance over SR 0018.

A third early action contract relocated portions of Foxwood Drive and the portions of the Homewood Viaduct. The third early action construction project was completed in late 2017.
