Special routes

The Port Authority provides special service to the Pittsburgh Steelers football games and select events at Heinz Field. Prior to the 2007 service cuts, a variety of special routes were implemented to facilitate travel from popular park and ride spots. Today, five special routes are offered, with increased service along standard lines during gamedays. Other special services are sometimes initiated for one-time events. These routes always end with the "S" character designation.

Route renumbering and realignments

Starting April 4, 2010, PAT will begin eliminating the number/letter route system that had been in place since its inception in 1964 – there are 124 routes, down from 168. In its place will be a new system that will incorporate several combined routes and a new number lineup with most of the routes being renamed. In addition, the light rail system and busways will be designated by colors:

• Red Line for the former 42-series light rail routes
• Blue Line for the former 47-series light rail routes
• Brown Line for the former 52 light rail route
• Green Line for the West Busway (Bus routes will begin with a "G")
• Purple Line for the Martin Luther King Jr. East Busway (Bus routes will begin with a "P")
• Orange Line for the I-279 North HOV lanes (Bus routes will begin with an "O")
• Yellow Line for the South Busway (Bus routes will begin with a "Y")
