Barge Traffic

Traffic data for the Port of Pittsburgh comes from the U.S. Army Corps of Engineers’ Waterborne Commerce Statistics Center and its Lock Performance Monitoring System.

Data about lock traffic is a good measure of lock activity, but is not as reliable or timely as a measure of actual tonnage; it’s reported only after a delay of as much as two years. The Port of Pittsburgh has 200 miles of commercially navigable waterways in 11 southwestern Pennsylvania counties.
