Route description

Southern terminus to 5 route concurrency

US 19 Truck begins as U.S. Route 19 enters Mount Lebanon as Washington Road. US 19 branches northwest to skirt Mt Lebanon and Dormont, while US 19 Truck continues through the centers of those towns. As US 19 Truck enters the southern parts of Pittsburgh, its name becomes West Liberty Ave as it passes through the West Liberty neighborhood. At the south portal of the Liberty Tunnel, US 19 Truck turns left onto Pennsylvania Route 51 (Saw Mill Run Boulevard).

After 1.4 miles, US 19 Truck exits PA 51 via a left exit toward I-279/US 22/US 30. Traffic headed for northbound 19-Truck and 279, and for eastbound 22/30, is joined by traffic headed for "southbound" 19 and 279 and "westbound" 22/30. At the top of a half-mile-long uphill ramp, traffic headed for south- and west-bound 279/22/30 joins the mainline highway, but traffic from 279-S/22-W/30-W headed for PA-51, US-19, and "southbound" US-19-Truck joins the ramp. 500 feet later, US-19-S branches off, and the ramp turns north. After another 1200 feet, traffic headed for northbound 19-Truck, southbound 19-Truck, northbound 279, eastbound 22/30, and PA-51 is joined by traffic from northbound 19; about 500 feet further on, all ramp traffic joins the main highway.

At this point, a single northeasterly highway is carrying north- "and" south-bound US-19-Truck, northbound US-19 and I-279, and eastbound US-22 and US-30. (Because the southwesterly ramp never joins the freeway, the opposite side of the road never carries more than I-279-S, US-22-W, US-30-W, and US-19-Truck-S.) 1000 feet further on, southbound US-19-Truck exits to join PA-51-S; and finally, after another 400 feet, northbound US-19 exits to join PA-51-N, and I-279-N/US-22-E/US-30-E/US-19-TRK-N enter the Fort Pitt Tunnel.

Fort Pitt Tunnel to Interstate 279 Interchange

I-279, US 19 Truck northbound, US 22, and US 30 continue towards the northeast. North of Exit 5C, I-279 and the other concurrencies (US 19 Truck/US 22/US 30) pass through the Fort Pitt Tunnel then on I-279 southbound, exit 5C leads to Pennsylvania Route 837 north. Then I-279, US 19 Truck, US 22, and US 30 cross the Monongahela River on the Fort Pitt Bridge. After the bridge, US 22 and US 30 leave the concurrency at exit 6; the western terminus of Interstate 376. I-376, US 22, and US 30 head eastward while I-279 and US 19 Truck head northward. Then I-279 and US 19 Truck cross the Allegheny River on the Fort Duquesne Bridge. North of the bridge, I-279 and US 19 Truck interchange the southern terminus of Pennsylvania Route 65 at exit 7B of I-279. Exit 7A is to PNC Park and exit 7B is for Heinz Field. At exit 7C and 8A, I-279 southbound splits into HOV lanes at the Interstate 279 Interchange. The Interstate 279 interchange involves the northern terminus of Interstate 579 and the southern terminus of Pennsylvania Route 28.

Exit 8 to northern terminus

North of Exit 8B, I-279 has no HOV lanes and continues its concurrency with US 19 Truck towards the north. At exit 11, US 19 Truck splits from I-279 and US 19 Truck continues towards the north at-grade as McKnight Road a divided highway. In Ross Township, US 19 Truck interchanges with Babcock Boulevard and shifts towards the northwest. In McCandless Township, US 19 Truck interchanges with Ingomar Road. Northwest of Ingomar Boulevard, US 19 Truck terminates (ends) at an interchange with U.S. Route 19.

History

Signed as U.S. Route 19 from 1941 to 1948. The route was signed in 1946 as a bypass route for trucks that weren't allowed on US 19. In 1948, the southern terminus was moved from Banksville Road to its current location. In 1989, US 19 truck's designation was moved to I-279 to form a complete US 19 Truck from Mount Lebanon to Wexford after the Parkway North was completed. In 1997, construction began on the interchange at the southern portal of the Liberty Tunnel, and opened to traffic on November 20, 1999.
