Rt 83 from Baltimore MD to York PA

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. A decision from the FHWA on the Environmental Assessment for Section 2 is anticipated for Spring 2020. Construction on these sections could start in 2023.
History
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 I-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, I-83 opened from Interstate 695 to Guilford Avenue by 1963, southward to Monument Street in the 1970s, and to Pleasant Street by 1983. The southernmost portion of I-83 in Baltimore opened by 1990.3
The southern end of I-83 was previously planned to link with Interstate 95 in Baltimore. An early proposal 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 I-83. However as was the case with many Baltimore freeway plans, community opposition canceled this portion of I-83.
