Port of Pittsburgh
"The Port of Pittsburgh is defined [by the United States Army Core of Engineers] as all of the locks and dams within southwestern Pennsylvania."
The Port of Pittsburgh, Pennsylvania is a vast river traffic region that encompasses a twelve county area including Allegheny, Armstrong, Beaver, Blair, Butler, Clarion, Fayette, Greene, Indiana, Lawrence, Washington, and Westmoreland Counties, essentially all 200 miles of commercially navigable waterways in southwestern Pennsylvania. It includes the three major rivers in southwestern PA: the Allegheny, the Monongahela, and the Ohio. This waterway is made navigable by a system of seventeen locks and dams. The Port of Pittsburgh supports over 200 river terminals and barge industry service suppliers, including privately owned public river terminals. The Port complex is served by the CSX and Norfolk Southern railroads and by four interstate highways. The Port of Pittsburgh Commission acts as a comprehensive service for shippers and industries seeking information on the river system.
Unlike the Port of Miami, for example, the Port of Pittsburgh, does not refer to a specific geographic location but to the broader geographical context under which the Pittsburgh port industry conducts its broad scope of activity.
