Report on a Recommended Subway in the First and Second Wards of Pittsburgh, or Proposed First Step in a Rapid Transit Program, City of Pittsburgh, Traffic Commission, Bureau of Traffic Relief (copy 2), 1925

Subseries 8 contains reports about mass transportation systems in Pittsburgh and other U.S. Cities. Particular reports of interest include those that reference mass transit systems that never came to fruition, including an underground subway system proposed by the Department of City Planning in the 1930s. In the mid-1960s, the Westinghouse Company’s Skybus project was proposed, which was a major mass transit proposal that would have provided continuous service via the Skybus rail.
