Interstate 283

Interstate 283 is a short auxiliary Interstate Highway located entirely within Dauphin County in the U.S. state of Pennsylvania. The highway serves as a vital connector between the Pennsylvania Turnpike (I-76) and the Harrisburg area, linking to major routes like U.S. Route 322 (US 322) and US 422. Its entire length is also designated as part of the US 283 corridor, providing a direct path to the state capital and its eastern suburbs.

Route description

The highway begins at a complex interchange with US 322 and US 422 in Swatara Township, near the community of Progress. From this southern terminus, it travels northward, passing the Harrisburg International Airport and crossing the Paxton Creek. The route then enters the city of Harrisburg, where it meets its northern terminus at a major interchange with the Pennsylvania Turnpike (I-76) and I-83, known locally as the Union Station interchange. The roadway is maintained by the Pennsylvania Department of Transportation (PennDOT) and traverses a mix of suburban and commercial landscapes.

History

The corridor was originally constructed as part of US 283, a route connecting Harrisburg to Lancaster. Planning for a high-speed link to the Pennsylvania Turnpike began in the 1960s to improve access to Harrisburg International Airport and the growing eastern suburbs. The highway was officially designated as part of the Interstate Highway System and opened to traffic in 1970. Since its opening, it has played a crucial role in the development of the Capitol City Airport area and the commercial corridors along Paxton Street.
