The Capital Beltway is a beltway surrounding Harrisburg, Pennsylvania, in the United States. It is co-designated as Interstate 81 (I-81), I-83, U.S. Route 11 (US 11), US 322, and Pennsylvania Route 581 (PA 581) at various locations along the route. The beltway is primarily located in the suburbs of Harrisburg on both sides of the Susquehanna River; however, part of its southern leg passes along the southern edge of downtown. The southern section of the highway is named the Harrisburg Expressway. Officially designated in 1997, the Beltway is an assemblage of several freeways built over the preceding 45 years. Route description Eastbound from the interchange of PA 581 at I-83 west of the city of Harrisburg in the borough of Lemoyne (colloquially known as the "York split"), the beltway crosses the Susquehanna River on the John Harris Bridge, connecting Harrisburg to its west shore (a colloquialism of the western bank of the Susquehanna across from Harrisburg) suburbs of the city. Continuing on I-83, the beltway parallels Paxton Street (formerly US 322), passing the Harrisburg Mall as the road approaches the Eisenhower Interchange. At the junction, the Capital Beltway continues on I-83 as it turns north, while beginning a concurrency with US 322. Continuing for three miles (5 km), I-83 ends at I-81 at an interchange locally known as the "81/83 split". US 322 and the Capital Beltway continue on I-81 south. On I-81, US 322 exits off I-81 at exit 67B, heading in a northerly direction to State College, beginning a concurrency with US 22 west. Exit 67A is for US 22 east, Cameron Street, which is where the Pennsylvania Farm Show Complex & Expo Center is located (a half mile south of the beltway). The Capital Beltway crosses the Susquehanna the second time on the George N. Wade Memorial Bridge. The beltway makes a southerly turn just beyond the bridge, near the western end of the Susquehanna Water Gap of Blue Mountain. Continuing on I-81 until exit 59, the Capital Beltway exits south onto PA 581. US 11 begins a concurrency with PA 581 starting at exit 3; at exit 5A it exits off and starts a concurrency with US 15 in the borough of Camp Hill. The beltway continues east for two miles (3 km) until it completes the loop by reaching I-83 at the York split. History The Capital Beltway was officially designated in 1997, an assemblage
