OVERVIEW

Duquesne Light Company is working with the Pennsylvania Turnpike Commission (PTC) to relocate several 138 kilovolt (kV) electric transmission lines in support of the Mon-Fayette Expressway project. 

The PTC is constructing a highway extension, starting with a new interchange on PA Route 51 in Jefferson Hills Borough and proceeding northward, crossing the Monongahela River with a new bridge, and terminating at Interstate 376 (the Parkway East) near Monroeville. 

The PTC has broken the project into several design sections. At this time, the PTC is funded to proceed with the engineering and construction of the Southern Design Sections (53A, 53B and 53C), which start in Jefferson Hills and end on the south side of the Monongahela River in the City of Duquesne.  Duquesne Light is working with the PTC to relocate several transmission lines in the Southern Design Sections.

Engineering and construction of the Mon-Fayette Expressway Northern sections will not begin until the late 2020s or early 2030s.


TIMING

DLC engineering is underway and construction currently is scheduled to begin in the summer of 2021 and to end in the spring of 2023.
