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

==Route description==
[[File:2021-10-28 15 55 30 View south along Interstate 283 just south of Exit 2 in Swatara Township, Dauphin County, Pennsylvania.jpg|thumb|left|I-283 southbound past PA&nbsp;441 in Swatara Township]]
I-283 begins at the Harrisburg East interchange of [[Interstate 76 in Pennsylvania|I-76]] ([[Pennsylvania Turnpike]]) in [[Lower Swatara Township, Pennsylvania|Lower Swatara Township]], [[Dauphin County, Pennsylvania|Dauphin County]]; this interchange is a [[trumpet interchange]]. Past the interchange toll plaza, the road continues north and immediately reaches a [[partial cloverleaf interchange]] with the [[Pennsylvania Route 283|PA&nbsp;283]] freeway that also has access to [[Pennsylvania Route 230|PA&nbsp;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, Dauphin County, Pennsylvania|Swatara Township]]. The road enters commercial areas as it comes to a [[diamond interchange]] with [[Pennsylvania Route 441|PA&nbsp;441]]. After that exit, the road continues northwest before turning north and passing an industrial park. I-283 comes to its northern terminus at the Eisenhower Interchange with [[Interstate 83 in Pennsylvania|I-83]]/[[U.S. Route 322 in Pennsylvania|US&nbsp;322]] ([[Capital Beltway (Harrisburg)|Capital Beltway]]), at which point the freeway continues north as part of I-83 northbound/US&nbsp;322 westbound along the Capital Beltway while I-83 southbound heads west along the Capital Beltway and US&nbsp;322 eastbound heads east on a freeway.<ref name=gm>{{google maps|url=https://maps.google.com/maps?f=d&source=s_d&saddr=40.21606,+-76.78624&daddr=40.25170,+-76.81195&hl=en&geocode=FfylZQIdwFVs-w%3BFTQxZgIdUvFr-w&mra=ls&sll=40.254606,-76.800871&sspn=0.014935,0.042272&ie=UTF8&t=h&z=13|title=overview of Interstate 283|accessdate=2010-12-04}}</ref><ref name=PennDOTDauphin>{{Cite FTP |title=Dauphin County, Pennsylvania Highway Map |url=ftp://ftp.dot.state.pa.us/public/pdf/BPR_pdf_files/Maps/GHS/Roadnames/dauphin_GHSN.PDF |year=2010 |server=[[Pennsylvania Department of Transportation|PennDOT]] |url-status=dead |access-date=2010-11-30 }}</ref>

==History==
[[File:I-283 NB from PA 441 overpass.jpeg|thumb|right|I-283 northbound at the PA 441 interchange in Swatara Township]]
Construction began on I-283 in 1968.<ref name="pahighways">{{Cite web|url=http://www.pahighways.com/interstates/I283.html|title=Pennsylvania Highways: Interstate 283|author=Jeffrey J. Kitsko|date=March 14, 2010|website=Pennsylvania Highways|access-date=September 28, 2018}}</ref> Previously, the Harrisburg East interchange of the Pennsylvania Turnpike connected directly to Eisenhower Boulevard. The section from the turnpike to PA&nbsp;441 opened in 1970 and included a short portion of what is now PA&nbsp;283, connecting Eisenhower Boulevard to the exit&nbsp;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|spell=in}} of PA&nbsp;283, the interchange between I-283 and PA&nbsp;283 is being improved.<ref name="283cloverleaf">{{Cite web|url=https://lancasteronline.com/news/local/work-begins-on-miles-of-route-part-of-b-project/article_fac68ba4-30f4-11e7-8389-6f0f2d5bcac5.html|title=Work begins on 6 miles of Route 283, part of $1B project to improve Capital Beltway|last=Knapp|first=Tom|date=May 5, 2017|publisher=[[LNP (newspaper)|Lancaster Online]]|access-date=September 28, 2018}}</ref> The ramp from westbound PA&nbsp;283 and northbound I-283 is being widened to two lanes, and the loop ramp from westbound PA&nbsp;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&nbsp;283. The project is projected to be completed in late 2020.<ref name="283cloverleaf"></ref>{{Update after|2020}}
