Pennsylvania Route 380

PA 380 / PA 286 junction

PA 380 begins along the ramps of the Bigelow Boulevard and Interstate 579 interchange in Downtown Pittsburgh, north of the former Civic Arena complex. The route proceeds east traversing Ammon Playground park in the Hill District. PA 380 also parallels Norfolk Southern's Pittsburgh Line and the PRT's Martin Luther King Jr. East Busway on this section of the four-lane Bigelow Boulevard. In the neighborhood of Polish Hill, PA 380 intersects the Bloomfield Bridge via eastbound ramp and westbound at-grade intersection; the bridge connects to Liberty Avenue and the Bloomfield neighborhood.[4]

In the Upper Hill section of the city, PA 380 turns east becoming Baum Boulevard. In East Liberty, the route splits into one-way pairs around a large traffic circle known as Penn Circle. PA 380 exits the circle onto Penn Avenue running southeast into the Larimer neighborhood. In Point Breeze, PA 380 overlaps PA 8 for two blocks, from Fifth Avenue to Dallas Avenue; PA 380 turns north onto Dallas Avenue while PA 8 continues on Penn Avenue. In the Homewood South area, PA 380 turns east onto Bennett Street. A few miles east, the route becomes Frankstown Road in East Hills, the easternmost neighborhood in the city Pittsburgh. Frankstown Road leads 380 out of the city and into the eastern suburban area.[5]

In the Penn Hills hamlet of Laketon Heights, the route intersects PA 130. In the hamlet of Rodi, PA 380 meets the northern terminus of PA 791 and begins an overlap with the Yellow Belt. Both routes take a more northern alignment into the northeastern portions of the township. Near the Alcoma Golf Club, PA 380 leaves the Yellow Belt, while turning east onto Saltsburg Road. Roughly east of the Pennsylvania Turnpike overpass in the borough of Plum, PA 380 begins an overlap with the Orange Belt at the intersection with Center Road near Boyce Park. At the New Texas Road junction, the belt turns north and leaves PA 380.[6]

PA 380 / PA 366 junction

As PA 380 enters Westmoreland County, the highway interchanges PA 286. PA 380 then proceeds on a northeast course along the Golden Mile Highway, a multi-lane divided highway with access ramps. Near Rolling Fields Golf Club, PA 380 interchanges PA 366. Past the interchange, the highway continues on its northeast alignment. In the Westmoreland Business Research Park area, PA 380 intersects the eastern terminus of PA 780. The route proceeds eastward to interchange PA 66 in the hamlet of North Washington. East of 66, PA 380 winds its way along the northern banks of the Beaver Run Reservoir and terminates at PA 286, a few miles west of Saltsburg.[7]
