As of a few years ago, some business leaders and municipal workers from Baldwin, Brentwood, Whitehall, as well as the City of Pittsburgh have collaborated to develop a master plan to rebuild Saw Mill Run Boulevard (Clairton Road south of Brownsville Road in Brentwood). This collaboration, called Economic Development South, plans to turn this corridor into a landscaped boulevard attractive to business development as well as pedestrians, bicyclists, and transit users. Their vision for this stretch of Route 51 includes:
- Rebuilt four-lane roadway with either landscaped median or tree-lined curbs to calm the speeds of vehicular traffic.
- Redevelopment of the existing buildings to allow for best use of the land and to promote business and economic development
- Improved transit access (i.e. transit shelters, wider sidewalks) to encourage recreational activity and promote a safe environment for bicyclists and pedestrians.
