At the village of Mount Morris, US 19 in West Virginia enters the state from Morgantown and then parallels Interstate 79 to the north. The road passes through a wooded area with hills. There are not too many places along the way, you mainly pass through small villages. After 60 kilometers you reach the town of Washington, the largest core in southwestern Pennsylvania. It crosses US 40 and Interstate 70 here. It doesn’t take long before you reach the first suburbs of Pittsburgh. US 19 also has 2×2 lanes from Washington.
Washington has in fact already grown into the Pittsburgh metropolitan area, the corridor of US 19 and I-79 to the north is already slightly urbanized here with some small suburbs. US 19 is then an important route connecting the southern suburbs, this area lacks a radial highway or a ring road, so all traffic in this area is dependent on local streets and roads. In Bethel Park there is a large mall next to the road and closer to Pittsburgh the suburbs are more densely built, but because of the hilly area there is no grid pattern or closely spaced houses. You then pass through the center of Mount Lebanon, a somewhat older suburb. Then the road descends a bit to Interstate 279, the main highway that handles north-south traffic in Pittsburgh. The US 22 and US 30 are also crossed here. Before the Fort Pitt Tunnel, the road turns north and forms a short highway itself to the West End Bridge, a bridge over the Ohio River. The road then continues on State Route 65, a short highway to Marshall Avenue and later Perrysville Avenue, leaving the Ohio River valley and into the northern suburbs. The road winds through the hills and crosses I-279 once more. The road then opens up the northern suburbs of Pittsburgh before crossing Interstate 76 at Cranberry.
North of Pittsburgh, the road again parallels I-79 and has 2×2 lanes for a while. The road then continues its route through a transition area from the flat Ohio to the Pennsylvania Hills. At the village of Rose Point, you cross US 422. The road then avoids most of the larger towns in the region, which are more to the west or east, and crosses Interstate 80 at Mercer. Shortly afterwards you cross the US 62. The area through which you pass is sloping with regular small forests. At Meadville, the US 6. joinsout of Cleveland and cross I-79 for the last time. The US 6 is then double-numbered over a distance of more than 30 kilometers. US 322 is also crossed in Meadville. The road then heads north from I-79 and at Indian Head, US 6 turns east toward Warren and Scranton. Then follow the last kilometers to the larger city of Erie. Interstate 90, where the road ends in downtown Erie on US 20.
US 19 was created in 1926. The northern terminus has always been Erie, and the route has not changed significantly in Pennsylvania since then. With the construction of the parallel Interstate 79 in Pennsylvania, the throughput decreased. I-79 was built in the 1960s and 1970s.
