Churchill–Monroeville business loop

U.S. Route 22 Business

Location	Monroeville, Pennsylvania
Length	5 mi (8.0 km)

U.S. Route 22 Business (US 22 Bus.) is a five-mile (8.0 km) loop through the eastern Pittsburgh suburbs of Churchill, Wilkins Township, and Monroeville, Pennsylvania, on William Penn Highway. The route's western terminus is at a freeway junction with Interstate 376 (I-376), which features a concurrency by the business loop's parent route. The route was the former pathway of US 22 itself before the construction that extended I-376 from this point eastward to the Pennsylvania Turnpike, in the early 1960s. The first two miles (3.2 km) of the road are contained in a valley, surrounded by a variety of side roads leading to suburban, mostly residential development. The remaining three miles (4.8 km) feature dense commercial development, including several office high rises and Monroeville Mall. The highway ends at a complicated junction that features the northern terminus of Pennsylvania Route 48 (PA 48), the southern end of Haymaker Road, and I-376, which features its last two exits (before the Pennsylvania Turnpike) with the above streets. US 22 Bus. then travels for its final eighth of a mile (0.201 km) on a viaduct that allows for connections with the Pennsylvania Turnpike and a smooth transition on to US 22 east (continuing William Penn Highway) toward suburban Murrysville.
