Pennsylvania Highways
Pittsburgh/Allegheny County Belt System

The system was originally developed by Joseph White, an engineer with the Allegheny County Department of Public Works, in the late 1940's using a network of federal, state and municipal that would offer drivers an alternate routes that did not lead into the congested Golden Triangle.

The Belt System was not intended as high speed or limited access roads, but instead their purpose was to define a road system way from the major arteries and the congestion that they suffered.  The colors of the system are ordered like the colors in a rainbow with the outermost red, followed by orange, yellow, green, blue, and purple.  So if you cross one color, you have an idea of how close you are to downtown and whether you are heading towards or away from the central business district.  

The Interstate Highway construction and Parkway construction from the late 1950s though the early 1970s reduced the use and need of the Belt System.  However, as urban sprawl got a hold of Pittsburgh, the system helped to reduce the effects of suburban congestion.  Many of the roads selected more than fifty years ago, still play a key role in the transportation plans for Allegheny County.  Many of them that were chosen for the belts have gone from country lanes to urban collectors to urban arterials.

In 1966, the belt took its current form between Truck US 19 and US 19 in Dormont.  Prior to that year, it followed Potomac Avenue, Dwight Avenue, and US 19 back to the intersection with Potomac.

In 1973, the route was moved from Kleber Street, Brighton Road, and Jacks Run Road to its current alignment between Benton Avenue and Bascom Street in Bellevue.  It was moved from Seavey Road, Parker Street, Butler Street, Bridge Street, and PA 8 between Evergreen Road and the Highland Park Bridge to its current alignment.  It was moved from Frankstown Road and Dallas Avenue to Fifth Avenue and Beechwood Boulevard between East Liberty and Squirrel Hill.

In 1974, the route was moved from Beechwood Boulevard onto the current alignment from Fifth Avenue to Browns Hill Road.  Signage was removed from PA 885, Glass Run Road, Churchview Avenue, Brownsville Road, and Maytide Street and placed on its current alignment between the Glenwood Bridge and Maytide Street.  In McKees Rocks, it was moved from Singer Avenue, Valley Street, Broadway, Seventh Street, and McCoy Road to the current alignment between Chartiers Avenue and PA 51.

In 1992, a leg of the belt which was signed on Shady Avenue and Monitor Street between Forward Avenue and Beechwood Boulevard was decommissioned.

History: Signed in the late 1940s.  The route originally followed Enlow Road near the airport, Mahoney Road in the western part of the county, Little Deer Creek Valley Road and Crawford Run Road through the northern sections of the county.  The designation was moved from these routes in the mid-1970s.  The designation changed to follow US 22/US 30 and PA 60 in 1972.  This belt was originally a complete circle, stretching into Washington County via Lovedale Road, Glassport and Elizabeth Road, PA 51, PA 837, Elrama Avenue, Finleyville-Elrama Road, to PA 88 and onward to its current terminus in Library.  This section was eliminated in the mid-1970s.  This belt still enters Westmoreland County, which makes it the only belt to enter another county besides Allegheny.
