to Mon/Fayette Expressway Project Environmental Decision Issued
Marks the Last of the Southern Beltway Projects to
Receive Federal Approval
The environmental Record of Decision (ROD) has been issued
for the proposed 12.5-mile Southern Beltway Project from I-79 to
the Mon/Fayette Expressway (Turnpike 43) at a new interchange
south of Finleyville. The U.S. Army Corps of Engineers signed
the ROD on May 13, 2009, which concludes the environmental
decision-making process for the estimated $730 million project.

The Pennsylvania Turnpike Commission is evaluating a
proposed 32-mile, tolled four-lane limited-access highway, known
as the Southern Beltway that would be located between PA Route
60 near the
Pittsburgh International Airport and the Mon/Fayette
Expressway (PA Route 43) near Finleyville, Pennsylvania. The
Southern Beltway consists of three projects for independent
development based on logical project end points, differing
project needs, and differing scheduling and funding
opportunities. The three project areas extend from PA Route 60
to U.S. Route 22 (opened to traffic in October 2006),
U.S. Route 22 to Interstate 79, and Interstate 79 to the
Mon/Fayette Expressway. Each of the three projects is
self-standing and will not curtail or obligate improvements in
other project areas along the corridor.
The primary purpose of the Southern Beltway
is to improve east‑west mobility, freight movement and
transit connections; stimulate local development; and link
the economically distressed Monongahela River Valley (Mon
Valley) with the
The Southern Beltway would enable people and goods to
move through the region safely and efficiently; increase
accessibility to areas of the region that are in a stage of
redevelopment and new growth; and improve access to other
areas which can provide markets to enhance the economic
vitality of the region.
The three Southern Beltway Projects in each of the
aforementioned specific areas would improve capacity,
safety, and travel times and contribute to the overall
accessibility and mobility of the transportation network.
The Interstate 79 to Mon/Fayette Expressway
Project of the Southern Beltway would support the orderly
economic development of the area between Interstate 79 and the
The existing local roads were built to serve early
farming and mining communities. These roadways are characterized
by steep grades, sharp curves, and narrow lanes and shoulders.
These roads are not capable of providing the needed
capacity and are inadequate to serve the projected growth in
this area. The
proposed project would provide a modern transportation facility,
which would help meet the future traffic demands for the area.
