The interchange between Interstate 83 and Business Loop I-83 was reconstructed as part of a $58 million project between 2003 and December 6, 2006 to provide full movements between the two expressways and eliminate the left exit.1


Interstate 83 comprises an older freeway running north from Baltimore, Maryland to Harrisburg, Pennsylvania. The freeway within the city of Baltimore is locally maintained, while the freeway throughout Baltimore County is maintained by the Maryland State Highway Administration.

Within Pennsylvania, I-83 leads north to York, where it takes an old bypass of U.S. 111 to the east. The freeway continues from there through hilly areas east of the Conewago Mountains to Cumberland County and the Harrisburg area. Turning east, I-83 spans the Susquehanna River to the south of Downtown Harrisburg. It turns north again at the Eisenhower Interchange to combine with U.S. 322 north to Progress, Colonial Park and the northern terminus at Interstate 81.

I-83 Capital Beltway Project

A major overhaul and upgrades of Interstate 83 through Harrisburg, Pennsylvania is underway as part of the I-83 Capital Beltway Project. Separated into four sections, construction addresses aging pavement, dated interchange design and capacity issues.

Work completed includes the I-83/PA 581 Interchange Bottleneck Safety Project, which addressed safety issues and congestion at the York Split exchange between the two freeways. A second lane was added for the I-83 mainline movement and weaving traffic patterns were addressed with ramp modifications and replacements. This interim improvement was completed in Summer 2015; long term plans call for constructing a systems interchange in place of the current trumpet at the York Split.

I-83 East Shore Section 1 widens Interstate 83 from north of the Eisenhower Interchange with I-283 south and U.S. 322 east to Interstate 81. Work also replaces bridges, adds sound barriers and further reconfigures the exchange with U.S. 22 at Exit 50. Split into two contracts, Section 1 work runs through late 2021.

I-83 East Shore Sections 2 and 3 will address the dated Eisenhower Interchange and expand the freeway between the Susquehanna River and Paxtang. Construction on these sections could start in 2022.

Parallel U.S. Routes

Interstate 83 replaced U.S. 111 from Baltimore north to Harrisburg.


Interstate 83 began as a short section of U.S. 111 freeway in 1950. By 1960, most of the U.S. 111 freeway in Pennsylvania was completed, just in time to be redesignated as Interstate 83. U.S. 111 was retired in 1963, and Interstate 83 was fully completed by 1971.2

Within Maryland, Interstate 83 also began as a freeway for U.S. 111, with initial completion by 1955. South of the Baltimore Beltway, Interstate 83 opened from Interstate 695 to Guilford Avenue by 1963, southward to Monument Street in the 1970s, and to Pleasant Street by 1983. The current southern terminus of Interstate 83 opened by 1990.3

The southern terminus was to have linked with Interstate 95 in Baltimore. An early plan took I-83 to a conclusion at I-95 within the Fells Point community. These alignments were later changed to move I-95 south to the Fort McHenry Tunnel and extend I-83 east through Canton. Stub ramps were built at the I-95 interchange with Boston and O’Donnell Streets for the planned junction with I-83. However as was the case with many Baltimore freeway plans, this portion of I-83 was canceled due to community opposition.

Baltimore, Maryland – 1976 Maryland Official Highway Map

The portion of Interstate 83 shown as proposed on the 1976 Maryland Map was never built. Interstate 70 east of Cooks Lane and the western leg of I-170 were equally unconstructed.

Harrisburg, Pennsylvania – 1971

Interstate 83 was completed in 1971, but the north end defaulted traffic onto Interstate 81 north until 1976, when I-81 was completed southward to Front Street and the George N. Wade Bridge across the Susquehanna River.5

North End I-81 US 322 – Colonial Park, Pennsylvania

Perspective from Interstate 83 north & U.S. 322 west
Interstate 83 northbound entered a full cloverleaf interchange (Exits 50A/B) with U.S. 22 (Jonestown Road) one mile south of I-81. Started in June 2016, the I-83 East Shore Section 1 project rebuilt this exchange into a parclo interchange, replaced the Jonestown Road overpass, and prepared the roadway for expansion to eight overall lanes. Photo taken 06/20/12.
I-83 expanded to three northbound lanes from U.S. 22 to Exit 51 for Interstate 81. Overheads pictured here were mounted on the Elmerton Avenue overpass. Contract 1 work for the I-83 East Shore Section 1 project replaced this span to accommodate widening in Contract 2. Expansion work runs from late 2018 to late 2021. Photo taken 06/20/12.
Crossing over Valley Road, Interstate 83 north & U.S. 322 west reach the three-wye interchange (Exit 51) with Interstate 81. U.S. 322 joins I-81 south for 2.25 miles, where it combines with U.S. 22 on a freeway extending north to Duncannon and Lewistown. Photo taken 06/20/12.
