Capital Beltway (Harrisburg)

The Capital Beltway begins at the interchange of the eastern terminus of PA 581 at I-83 2 miles (3.2 km) west of the city of Harrisburg in the borough of Lemoyne. This junction is colloquially known as the "York split".[3] From the 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".[4][5] 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 Farm Show Arena Complex 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 onto PA 581, also known as the Harrisburg Expressway. US 11 begins a concurrency with PA 581 starting at exit 3, and then exits off and starts a concurrency with US 15 in the borough of Camp Hill, at the Camp Hill Shopping Center (formerly Camp Hill Mall). The beltway continues for two miles (3 km) until it completes the loop by reaching I-83 at the York split.

The I-81 and I-83 sections of the beltway were both fully completed by the 1970s. An expressway connecting I-81 to I-83 had been planned, and the portion of the highway from the York split to US 11 and US 15 in Camp Hill was completed in 1992. It became known as the Harrisburg Expressway, and it was given the PA 581 designation. The section from Camp Hill to I-81 remained incomplete until 1995 when construction began on the segment. It was finally completed and opened for public use in 1997. The PA 581 designation was extended northwestward to the interchange with I-81 when it opened. The Capital Beltway designation was assigned to its current alignment at this time. Engineering for the project was provided by Gannett Fleming and McCormick Taylor of Camp Hill.

On May 9, 2013, a tanker crashed and caught fire at the interchange between I-81 and US 22/US 322 in Harrisburg. The fire damaged the bridges carrying westbound US 22/US 322 and a ramp over I-81. At least one of those bridges, carrying US 22 eastbound over I-81 and several ramps, and possibly another, the ramp carrying traffic from I-81 northbound to US 22/US 322 westbound, will have to be demolished and replaced. The fire resulted in about ten miles of I-81, from the PA 581 interchange to the I-83 interchange, being closed in both directions, with traffic being diverted along the southern portion of the Capital Beltway.[6][7]
