The Martin Luther King Jr. East Busway is a two-lane bus-only highway serving the city of Pittsburgh and many of its eastern neighborhoods and suburbs.It was named after Martin Luther King Jr. in recognition of the eastern portion of the route's serving many predominantly African-American neighborhoods, such as Wilkinsburg and East Liberty.The Institute for Transportation and Development Policy (ITDP), under its BRT Standard, has given the East Busway corridor a Bronze ranking.[1] Originally occupied by a railroad line, planning for the East Busway began shortly after the Port Authority of Allegheny County purchased the Pittsburgh Railways Company in 1964.These routes operate primarily during weekday rush hours allowing buses to bypass the heavily congested Parkway East (Interstate 376), making for faster trip times.
