MILEPOST 110.12 – NORTH CENTER AVENUE BRIDGE REPLACEMENT

Overview

overhead B-502 bridge

This project involves the replacement of overhead Bridge No. B-502 at Turnpike Milepost 110.12 which carries North Center Avenue (S.R. 601) over the Pennsylvania Turnpike mainline. This project is located in the municipalities of Somerset Borough and Somerset Township, in Somerset County.

This project will provide roadway surface improvements as well as roadway and pedestrian safety enhancements. Upon completion the existing single span thru-girder bridge will be upgraded to a two-span steel plate girder bridge. The proposed structure will carry two 11 foot travel lanes, a center 14 foot turning lane, a four foot shoulder with a five foot curbed sidewalk on the western side of the bridge and a nine foot shoulder on the eastern side of the bridge. The proposed bridge and road work will tie into the existing North Center Avenue (State Route 601) on the same existing roadway alignment.

During construction of the new bridge, a two lane temporary bridge will be constructed adjacent to the existing bridge to maintain N. Center Ave. traffic. A walkway will be attached to the temporary bridge for pedestrian traffic over the Turnpike during construction. A short portion of Water Works Road where it intersects with SR 601 and the northern entrance to the Wendy’s/Verizon Plaza will be closed during construction. A temporary access to the Wendy’s/Verizon plaza will be placed opposite to the Ruby Tuesday/Starbucks entrance with a temporary signal and separate left turn lane at this intersection. A short portion of Snyder Street where it intersects with SR 601 will be closed on the north side of the project area. There will be alternate routes signed for the temporary intersection closures of Water Works Road and Snyder Street. The intersection closures will provide needed space for the temporary bridge and roadway to connect back into SR 601 on both sides as well as for other construction activities.

The proposed bridge replacement and approach work will cost an estimated 7.5 million dollars and is fully funded by the Pennsylvania Turnpike Commission toll revenue. Construction is scheduled to begin in Spring 2018 for completion by Fall 2019.

The design and construction of this project is being administered by the Pennsylvania Turnpike Commission with the participation of PennDOT District 9-0.
