Interstate 99 (I-99) is an interstate highway in the United States with two segments: one located in central Pennsylvania and the other in southern New York. The southern terminus of the route is near exit 146 of the Pennsylvania Turnpike (I-70/I-76) north of Bedford, where the road continues south as U.S. Route 220 (US 220). The northern terminus of the Pennsylvania segment is at an at-grade intersection with Musser Lane just before reaching I-80 near Bellefonte. The New York segment follows US 15 from the Pennsylvania–New York border to an interchange with I-86 in Corning. Within Pennsylvania, I-99 passes through Altoona and State College—the latter home to the Pennsylvania State University—and is entirely concurrent with US 220. Long-term plans call for the two segments of I-99 to be connected using portions of I-80, US 220, and US 15 through Pennsylvania.
Interstate 376 (I-376) is a major auxiliary route of the Interstate Highway System in the US state of Pennsylvania, located within the Allegheny Plateau. It runs from I-80 near Sharon south and east to a junction with the Pennsylvania Turnpike in Monroeville, after having crossed the Pennsylvania Turnpike at an interchange in Big Beaver. The route serves Pittsburgh and its surrounding areas and is the main access road to Pittsburgh International Airport (PIT). Portions of the route are known as the Beaver Valley Expressway, Southern Expressway, and Airport Parkway. Within Allegheny County, the route runs along the majority of the Penn-Lincoln Parkway, known locally as Parkway West and Parkway East. It is currently the ninth-longest auxiliary Interstate route in the system and second only to I-476 within Pennsylvania.
Interstate 476 (I-476) is a 132.1-mile (212.6 km) auxiliary Interstate Highway of I-76 in the U.S. state of Pennsylvania. The highway runs from I-95 near Chester north to I-81 near Scranton, serving as the primary north–south Interstate corridor through eastern Pennsylvania. It consists of both the 20-mile (32 km) Mid-County Expressway, locally referred to as the "Blue Route", through Delaware and Montgomery counties in the suburban Philadelphia area, and the tolled, 110.6-mile (178.0 km) Northeast Extension of the Pennsylvania Turnpike, which connects the Delaware Valley with the Lehigh Valley, the Pocono Mountains, and the Wyoming Valley to the north.
The Schuylkill Expressway, locally known as "the Schuylkill", is a freeway through southern Montgomery County and the city of Philadelphia. It is the easternmost segment of Interstate 76 (I-76) in the U.S. state of Pennsylvania. It extends from the Valley Forge interchange of the Pennsylvania Turnpike in King of Prussia, paralleling its namesake Schuylkill River for most of the route, southeast to the Walt Whitman Bridge over the Delaware River in South Philadelphia. It serves as the primary corridor into Philadelphia from points west. Maintenance and planning for most of the highway are administered through Pennsylvania Department of Transportation (PennDOT) District 6, with the Delaware River Port Authority (DRPA) maintaining the approach to the Walt Whitman Bridge.
Interstate 176 (I-176) is a spur route of eastern I-76 in Berks County, Pennsylvania.

The Mon–Fayette Expressway is a partially-completed controlled-access toll road that is planned to eventually link Interstate 68 near Morgantown, West Virginia with Interstate 376 near Monroeville, Pennsylvania. The ultimate goal of the highway is to provide a high speed north–south connection between Morgantown and the eastern side of Pittsburgh while revitalizing economically distressed Monongahela River Valley towns in Fayette and Washington counties, serving as an alternative to Interstate 79 to the west, as well as relieving the PA 51 alignment from Pittsburgh to Uniontown.

The northern terminus is at US 9W north of Kingston in Ulster, New York, where the road continues east as NY 199.
The Delaware State Route System consists of roads in the U.S. state of Delaware that are maintained by the Delaware Department of Transportation (DelDOT). The system includes the portions of the Interstate Highway System and United States Numbered Highways system located in the state along with state routes and other roads maintained by DelDOT. All roads maintained by the state are assigned a maintenance road number that is only marked on little white markers at intersections and on auxiliary plates below warning signs approaching intersections. These numbers are only unique in a specific county; some roads can be designated with multiple road numbers, and numbers do not necessarily correspond to the signed Interstate, U.S., or state route numbers. DelDOT maintains a total of 5,386.14 miles (8,668.15 km) of roads, comprising 89 percent of the roads within the state. Some large bridges in the state are maintained by other agencies including the U.S. Army Corps of Engineers and the Delaware River and Bay Authority. Roads in the system include multilane freeways, multilane surface divided highways, and two-lane undivided roads serving urban, suburban, and rural areas. Some of the roads maintained by DelDOT are toll roads, in which motorists must pay to use.
