South Busway

Opened in December 1977, the first busway serves downtown Pittsburgh, Station Square, and the neighborhoods of the South Hills. It is a bypass of the Liberty Bridge and Tunnel and the traffic that both cause on PA 51/Saw Mill Run Boulevard.  Most bus routes through the South Hills will travel the busway into the city.  It carries 16 express and local route buses, carrying 13,000 passengers daily or nearly 4 million annually.  While others were built with the idea of conversion to a LRT right-of-way, this one shares part of its with the subway known as The "T."  The dual-use tunnel through Mount Washington, which it used exclusively until 1985 when the subway opened.
