According to bestitude, State Route 576 is a state route and toll road in the U.S. state of Pennsylvania. The highway is also known as the Southern Beltway and should eventually form a southern ring road around Pittsburgh. A 29-mile route southwest of Pittsburgh is currently being completed.

Travel directions

State Route 576 begins at an interchange with Interstate 376 at the Pittsburgh International Airport. The highway then has 2×2 lanes and runs first southwest to US 22 and then southeast to Interstate 79 south of Pittsburgh. The highway leads through a hilly area and has a number of valley viaducts. There is a complex and stretched interchange with I-79.


The first section of the route between I-376 and US 22 was opened to traffic on October 11, 2006.

In 2008 and 2009, decisions were taken for the southern ring road. The implementation was originally planned for the 2014-2020 period, although the first works only started in January 2017. The goal was to open the highway to I-79 in 2019, but completion was delayed to October 15, 2021. It was the Pittsburgh region’s first major new road connection since 1989. Work on the interchange with I-79 will continue until June 25, 2022.

It is planned to extend the highway east to State Route 43 at Finleyville, creating a southern bypass of the Pittsburg region. In 2021, the western part of this will be opened up to I-79. The next phase is an extension to State Route 43. It is not yet known when this section between I-79 and PA-43 (Mon-Fayette Expressway) will be built. A further phase up to the Pennsylvania Turnpike is costly because of a large bridge over the Monongahela River that would be required.

State Route 576 will be renumbered as Interstate 576 upon completion, as will an extension of State Route 43 to the Pennsylvania Turnpike at Monroeville. This will create a complete southern bypass of Pittsburgh.


State Route 576 is a toll road, part of the Pennsylvania Turnpike Commission. There is open road tolling with portals, there are no physical toll stations.

State Route 581 or SR-581 is a state route and freeway in the U.S. state of Pennsylvania. The highway forms the western approach road to the Harrisburg metropolitan area, the state capital. The highway is 12 kilometers long.

Travel directions

The highway begins at a junction with Interstate 83 and first has 2+3 lanes until the cloverleaf with US 15. After that, the highway has 2×2 lanes and bends to the northwest. The highway continues through the western suburbs of Harrisburg and ends at a half stack with Interstate 81. State Route 581 forms the southwestern portion of the Capital Beltway around Harrisburg.


The eastern section between I-83 and US 15 is the oldest, the exact date of construction is unknown. In 1992, a 4-kilometer section between US 11 and US 15 opened. The missing link to I-81 was built in 1995-1996. The cloverleaf with US 15 was notorious, traffic going up and down State Route 581 had to deal with very short mergers and no hard shoulder. There wasn’t even a weave between the two clover loops because the US 15 overpass over State Route 581 was so short. The cloverleaf was replaced between 2008 and 2011. A viaduct over the track between I-83 and US 15 was also replaced, allowing 3 lanes to the east.

Traffic intensities

Every day, 83,000 vehicles travel on the section between I-83 and US 15 and 53,000 vehicles continue to US 11. The last section up to I-81 processes 45,000 vehicles per day.

According to biotionary, State Route 63 or SR-63 is a state route in the U.S. state of Pennsylvania. The road is located in the Philadelphia metropolitan area and is partially a highway. The route is 58 kilometers long.

Travel directions

The road begins as a freeway at the interchange with Interstate 95, and runs northwest as Woodhaven Road. The highway section soon ends at US 1 in northeast Philadelphia. Thereafter, SR-63 continues through a number of TOTSOs through the Philadelphia suburban area as a secondary thoroughfare.


In 1954, plans for a 2×3 highway as the Woodhaven Road were approved by the City of Philadelphia. Construction did not begin until 8 years later, in 1962. The first section opened between I-95 and US 13 for 1 kilometer in 1963. In 1966, Woodhaven Road was extended to its current end at US 1.

Not built

In the late 1950s there were plans to extend the highway to Doylestown, well north of Philadelphia. These plans never materialized, although they have been raised several times since the 1970s.

Traffic intensities

Between 49,000 and 65,000 vehicles drive daily on the highway section called Woodhaven Road in eastern Philadelphia.
