PRT Busways Carry Historic Significance

It might not be widely known, but Pittsburgh was one of the first cities in the U.S. to experiment with the concept of a dedicated bus rapid transit system. The idea of committed bus-only lanes emerged in the 1960’s as part of a broader vision for modernizing Pittsburgh’s transit infrastructure, following the decline of its streetcar network. Pittsburgh needed efficient, reliable public transportation - a tall order thanks to our challenging topography and dense urban layout. Pittsburgh Regional Transit (known as the Port Authority of Allegheny County at that time) sought to create a cost-effective system that could leverage existing bus fleets while offering the speed and reliability of a light rail system. 

In 1977, the South Busway was the first busway to open. Running parallel to South Hills Junction and following the path of a combination of two former streetcar and one existing freight railroad rights-of-way, it provided a dedicated corridor for buses, reducing congestion on local roads and improving commute times for residents in Pittsburgh’s southern neighborhoods. Encouraged by its success, PRT expanded the system with the Martin Luther King Jr. Busway in 1983, a 9.1-mile stretch connecting Downtown Pittsburgh with the eastern suburbs. This busway became a model for high-frequency, limited-stop service and to this day is one of the most successful bus rapid transit corridors in the country.

In 2000, the West Busway further extended the network and enhanced connectivity for commuters traveling from the western suburbs and Pittsburgh International Airport. This busway boasted more grade-separated sections which further improved travel times. Over the years, our busways have served as inspiration for BRT systems in cities across the country.

Construction is wrapping up for phase one of PRT’s current bus rapid transit project - The University Line. The University line will operate between Downtown, Uptown, and Oakland with bus service extending through the East End and beyond. Phase Two construction will begin in early spring of 2025.

The busways and BRT expansions play a crucial role in Pittsburgh’s transportation network. They have proven effectiveness in a city with steep hills, winding roads, and a strong need for reliable public transit. Today, the busways remain a vital part of the region’s transit system, carrying thousands of riders daily and offering a model of flexible, high-capacity urban transportation.
