It travels from the Harrisburg East interchange of I-76 (Pennsylvania Turnpike) north to I-83/US 322 (Capital Beltway) at the Eisenhower Interchange. Pennsylvania Route 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. Route descriptionI-283 begins at the Harrisburg East interchange of I-76 (Pennsylvania Turnpike) in Lower Swatara Township, Dauphin County. Past the interchange tollbooth, the road continues north and immediately reaches a cloverleaf interchange with the PA 283 freeway that also has access to PA 230 via Eisenhower Boulevard. I-283 continues north-northwest as a four-lane freeway, running past business parks before entering areas of farms and woods, crossing into Swatara Township. The road enters commercial areas as it comes to a diamond interchange with PA 441. After that exit, the road continues northwest before turning north and passing an industrial park. I-283 comes to an end at the Eisenhower Interchange with I-83/US 322 (Capital Beltway), at which point the freeway continues north as part of I-83/US 322.[2][3] HistoryConstruction began on the interstate in 1968.[4] Previously, the Harrisburg East interchange of the Pennsylvania Turnpike connected directly to Eisenhower Boulevard. The section from the Turnpike to PA 441 opened in 1970 and included a short portion of what is now PA 283, connecting Eisenhower Boulevard to the Exit 1 cloverleaf. The next year, the Eisenhower Interchange opened to traffic along with the remaining section of interstate. As part of a project to reconstruct {{convert|6|mi|km}} of PA 283, the interchange between I-283 and PA 283 is being improved.[5] The ramp from westbound PA 283 and northbound I-283 is being widened to two lanes, and the loop ramp from westbound PA 283 to southbound I-283 toward the Pennsylvania Turnpike toll plaza will be removed and replaced with a left turn and a traffic signal. This will eliminate the problem of traffic weaving between the aforementioned loop ramp and the heavily-traveled loop ramp from southbound I-283 to eastbound PA 283. The project is projected to be completed in late 2020.[5] Exit list{{jcttop|old|exit|state=PA|county=Dauphin|length_ref=[1]|exit_ref=[8]|old_ref= [6]}}{{PAint|old |location=Lower Swatara Township |ctdab=Dauphin |lspan=3 |type=toll |feet=0 |old=– |exit=– |road={{jct|state=PA|I-Toll|76|PATP|city1=Philadelphia|city2=Pittsburgh}} |notes=Southern terminus}}{{PAint|old |feet=87 |mspan=2 |old=2E |exit=1A |road={{jct|state=PA|PA|283|extra=airport|dir1=east|location1=Harrisburg International Airport|city2=Lancaster}} |notes=Last free exit southbound; Access to Eisenhower Blvd via Exit 1B |nspan=2}}{{PAint|old |mile=none |old=2W |exit=1B |road={{jct|state=PA|PA|230|to1=To|city1=Highspire}} |notes=none}}{{PAint|old |location=Swatara Township |lspan=4 |ctdab=Dauphin |feet=9823 |old=1 |exit=2 |road={{jct|state=PA|PA|441|location1=Swatara}} |notes=}}{{PAint|old |feet=15348 |mspan=3 |old=– |exit=3A |road={{jct|state=PA|I|83|name1=Capital Beltway|dir1=south|city1=Harrisburg}} |notes=Northern terminus; Eisenhower Interchange |nspan=3}}{{PAint|old |mile=none |exit=3B |old=– |road={{jct|state=PA|I|83|US|322|to3=To|I|81|name1=Capital Beltway|dir1=north|dir2=west|city1=Hazleton|city2=Lewistown}} |notes=none}}{{PAint|old |mile=none |exit=3C |old=– |road={{jct|state=PA|US|322|city1=Hershey}} |notes=none}}{{jctbtm|old|exit|keys=toll}} See also
