Pennsylvania Canal in Pittsburgh
Three Rivers Heritage Trail
When packet boats moved into the canal from the river, mules pulled the vessels through four canal locks to reach a spectacular tunnel built through Grant's Hill, where the courthouse stands today. Boats plunged into the dark tunnel and emerged near Liberty Avenue. This canal tunnel, one of the first built in the United States, was as impressive a structure as people in the 1830s had ever seen. Thirty-five years later, after the canal tunnel was abandoned, the Panhandle Railroad built a second tunnel near the abandoned canal tunnel.
When the canal opened through Pittsburgh in 1831, a great ceremony was held on this site at Lock #1, known as the Washington Lock. This lock was constructed to join two famous canal systems—the Pennsylvania Canal and the Chesapeake and Ohio Canal (C&O) coming from the Potomac River near Washington, D.C. The never made it this far north.
