The Pennsylvania Canal Tunnel was the Pittsburgh terminus of the Pennsylvania Main Line of Public Works, a transportation system that involved other early tunnels. Construction was authorized February 8, 1827, and the tunnel was completed November 10, 1829. The canal crossed the Allegheny River on a covered bridge aqueduct, later replaced by John A. Roebling's first suspension bridge, the Allegheny Aqueduct., the canal traveled underground through most of downtown Pittsburgh, under Grant's Hill, to end in a lock leading to the Monongahela River. The original plan was to connect with the C&O canal at the Monongahela River, but that canal never reached its expected western end, and the tunnel's main use was to allow overflow from the canal to enter the Monongahela. Only one or two canal boats ever went through the tunnel and lock. The tunnel was made obsolete by the arrival of the Pennsylvania Railroad in 1852. The canal tunnel was uncovered during the construction of the U.S. Steel Tower in 1967, and later during the construction of the subway system, which used part of the tunnel on the south side.

The Stadium Authority of the City of Pittsburgh (also known as the Stadium Authority) is a municipal authority that was charged with the construction of Three Rivers Stadium and the management of the land on which it stood following its 2001 demolition.It currently owns the West General Robinson Street Garage and surface parking lots near PNC Park and Heinz Field. The Stadium Authority also leases parking facilities north of PNC Park. It was formed on March 9, 1964 by the City of Pittsburgh under its authority under the Public Auditorium Authorities Law of the Commonwealth of Pennsylvania. The Stadium Authority board is comprised on five members, all appointed by the Mayor of Pittsburgh. In 2003, the Stadium Authority began a development project in an area called the "Option Area" that allowed the Pittsburgh Steelers and the Pittsburgh Pirates to develop commercial property in conjunction with North Shore Developers. The plan currently has completed the Equitable Resources building and the Del Monte Building.The Pittsburgh Intergovernmental Cooperation Authority, a special administrative authority that supervises the finances of the City of Pittsburgh, has said that the Stadium Authority is no longer necessary and recommended in 2004 that its duties be consolidated into the Sports & Exhibition Authority of Pittsburgh and Allegheny County. However, as of 2016, the Stadium Authority still exists and continues to manage parking lots in the North Shore area. This incongruity has led to some wry attention from local journalists and pundits—for example, University of Pittsburgh economist Chris Briem has referred to it as the "Stadium(less) Authority".
