Interstate 283 (I-283) is an auxiliary route of the Interstate Highway System located just east of Harrisburg, Pennsylvania. It travels from the Harrisburg East interchange of I-76 (Pennsylvania Turnpike) north to I-83/U.S. Route 322 (US 322, Capital Beltway) at the Eisenhower Interchange. Pennsylvania Route 283 (PA 283, officially designated as SR 300 because of I-283) continues southeast from near the southern terminus of I-283 to Lancaster as a freeway, functioning as an extension of the Interstate, though they are two separate roads.
