The Southwestern Pennsylvania Commission (SPC) MPO includes ten counties in southwestern Pennsylvania : Allegheny, Armstrong, Beaver, Butler, Fayette, Greene, Indiana, Lawrence, Washington, and Westmoreland Counties as well as the City of Pittsburgh.  The SPC activities support the operation, maintenance and improvement of a multi-faceted transportation system that provides a strong backbone for personal and freight travel.

 

Major Corridors within the region include:

Major East-West Corridor

I-70, I-76, I 376

Major North-South Corridor

I-79, and the Mon-Fayette Expressway

Transit

The SPC region is well served by eleven public transportation service providers.  These are Port Authority of Allegheny County (PAAC), Mid Mon Valley Transit Authority (MMVTA), Beaver County Transit Authority (BCTA), the City of Washington Transit (WCT), Butler City-Township Joint Municipal Transit Authority (BTA), Indiana County Transit Authority (Indigo), Mid-County Transit Authority (Town & Country Transit), Westmoreland County Transit Authority (WCTA), Fayette Area Coordinated Transportation (FACT), New Castle Area Transportation Authority (NCATA), and the Southwestern Pennsylvania Commission (CommuteInfo Program).  PAAC Transit is the regions’ largest and a primary provider of intra-city public transportation services.  Port Authority’s North Shore Connector now extends the Light Rail system from Pittsburgh’s Golden Triangle under the Allegheny River to the North Shore.

 

Aviation

Pittsburgh International Airport (PIT) is a world-class facility that serves more than 8 million travelers annually.  The airport is served by 12 air carriers and their subsidiaries.  Several air cargo carriers also operate from this facility.  The region’s other 16 public airports provide additional services for local travelers and support a thriving general aviation community.  The Arnold Palmer Regional Airport in Latrobe also supports commercial aviation service.

 

Rail Freight

Southwestern Pennsylvania is served by three Class I railroads: CSX, Norfolk Southern (NS) and Canadian National (CN), as well as

16 regional and short-line railroads along more than 1,300 miles of track. NS operates the region’s largest truck intermodal center at Pitcairn.  Canadian National has trackage rights into a relatively new intermodal facility in New Stanton, Westmoreland County.

 

Water Freight

The region’s river system supports Pittsburgh’s status as one of the nation’s largest inland ports.  Coal barges traveling the three major rivers provide fuel for the region’s power plants and for export. Major lock and dam improvements underway on the Monongahela River system will have a significant impact on operating efficiency in this corridor when these projects are completed.  The Upper Ohio Navigation Study, designed to assess the infrastructure condition and rehabilitation needs of the locks and dams on the Upper Ohio River, including the Emsworth, Dashields and Montgomery Locks and Dams in the SPC region, is currently underway.  SPC participates in study activities as a member of the Inter-Agency Working Group.
