The Port Authority-owned Wabash Tunnel provides a shortcut for motorists from Route 51 to the South Side and Downtown Pittsburgh. The centuries-old former railroad tunnel was opened as a commuter tunnel in December 2004.

The tunnel operates as HOV-2 (minimum of two occupants) during peak periods and is available to general automobile traffic during non-peak, evening and weekend periods:
