HOV restrictions lifted from Wabash Tunnel


The Wabash Tunnel’s HOV+2 restriction during peak hours temporarily has been lifted effective Monday, Nov. 11, to provide an additional option for motorists during the Pennsylvania Department of Transportation’s (PennDOT) West Carson Street project. The Tunnel provides a shortcut for motorists between Route 51 and South Side/Downtown Pittsburgh.

The Federal Transit Administration approved temporarily lifting the HOV+2 restriction at the tunnel until December 2015. The authority, consistent with the temporary federal approval granted, intends to restore the HOV+2 restriction in December 2015.

Motorists using the Wabash Tunnel are advised to read posted signage, which indicates the available direction of travel and speed limits. Only one direction of traffic is permitted at a time and, on weekdays, adjusts with the rush hours. The speed limit is 25 mph and reduces to 15 mph on curves.

Motorists should also be advised that no vehicle over 13 feet and one inch in height is permitted in the tunnel. Tractor-trailers and similar commercial vehicles are also strictly prohibited from using the tunnel, as well as any vehicle transporting flammable liquids or explosives.

More information about using the tunnel, including hours of operation and direction, is available at
