Interstate 83


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.

Parallel/Historic 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.


Highway Guides

Southern Terminus - Baltimore, Maryland - Downtown
Perspective from Interstate 83 south
Expressway Ends - 2 Miles overhead placed on Interstate 83 southbound at Exit 3/Guilford Avenue. Vidcap taken 10/16/93.
Pleasant Street/Exit 2, departs from Interstate 83 southbound, as the downtown skyline graces the horizon. The pentagonal high-rise behind the Pleasant Street guide sign is that of the Baltimore World Trade Center.1 The building is located within the Inner Harbor area of the city, and features an observation deck on the top floor. Photo taken by Tim Reichard (09/14/02).
A closer view of the sign bridge Pictured in the above photobox. Interstate 83 curves towards the southeast before its terminus. Originally the highway was to make an eastward turn from roughly this point to Interstate 95. Guide signage is also posted for the world-renown John Hopkins Medical Campus for the south end of the freeway. Photo taken by Tim Reichard (09/14/02).
Fayette Street/Exit 1 overhead guide signage on Interstate 83 southbound. This is the last exit of the freeway. Photo taken by Tim Reichard (09/14/02).
Last southbound Interstate 83 reassurance shield. Note that the faded shield still contains the state name of Maryland. Photo taken by Tim Reichard (09/14/02).
The last mile of the expressway is very windy, a compromise necessitated by the restructured terminus to coincide with President Street. Speed limits drop from 40 to 35 MPH rapidly. Photo taken by Tim Reichard (09/14/02).
Last exit of Interstate 83 south. Actually, this is a right-turning lane to Fayette St. westbound, serving the downtown area. Photo taken by Tim Reichard (09/14/02).
This signalized intersection with Fayette Street represents the southern terminus of Interstate 83. Traffic continuing straight enters President Street, a short alignment that dead-ends at the Inner Harbor not far from this crossing. Photo taken by Tim Reichard (09/14/02).
Perspective from President Street north
Fleet Street westbound at the beginning of President Street northbound. The Inner Harbor tourist district is straight ahead while Interstate 83 is nine blocks to the right. Photo taken 06/02/03.
President Street northbound meets Eastern Avenue at this intersection. Eastern Avenue follows roughly the planned path of Interstate 83 from President Street to Interstate 95. Otherwise Interstate 83 begins eight blocks to the north of this turn. Photo taken 06/02/03.
Lombard Street westbound next approaches President Street, two blocks south of Fayette Street and Interstate 83. Photo taken by Tim Reichard (09/14/02).
Northbound on President Street at Baltimore Street, one block south of Fayette Street and Interstate 83. The building to the right is Shot Tower. Photos taken by Tim Reichard (09/14/02) and on 06/02/03.
One block further north, President Street meets Fayette Street. Motorists are offered a choice between Interstate 83 (Jones Falls Expressway) or The Fallsway, a virtual frontage road below the Interstate 83 viaduct that ultimately becomes Maryland 25. Another access ramp to Interstate 83 northbound is available from The Fallsway just a few short blocks to the north. Photos taken by Tim Reichard (09/14/02) and Chris Elbert (07/06).
Perspective from Interstate 83 north
The northbound beginning of Interstate 83, the Jones Falls Expressways. Baltimore residents refer to Interstate 83 within the Beltway as simply The JFX. The photograph shows a guide sign for Interstate 83, posted just past the President Street transition to Interstate 83 at Fayette Street (see above photograph). The exit numbers for Interstate 83 within the city limits of Baltimore do not coincide with the actual mileage. It is believed that the numbering system is still sequentially based, as was the original standard for all Maryland Interstate highways until the late 1980s. Note the addition of a blue Interstate Highway System trailblazer to the overhead sign. Photos taken by Chris Elbert (07/06) and Tim Reichard (09/14/02).
First northbound Interstate 83 reassurance shield, posted midway between Fayette Street and Chase Street. The on-ramp from below brings traffic onto the freeway from Gay Street. Northbound traffic can access the city street via The Fallsway Chase Street, the first northbound off-ramp, is still several blocks to the north. The viaduct in the background is that of U.S. 40 (Orleans Street Viaduct). Photos taken 06/02/03 and by Tim Reichard (09/14/02).
The northern reaches of the Baltimore skyline still dominate the horizon as Interstate 83 begins. The city is home to 651,154 residents while an additional 754,292 Marylanders call Baltimore County home. This reassurance shield is posted shortly after the last one. Photo taken by Chris Elbert (07/06).
Northern Terminus - Interstate 81 - Colonial Park, Pennsylvania
Perspective from Interstate 83 north
Interstate 81/Exit 51A/B advance guide signage, posted at the U.S. 22/Exits 50A/B cloverleaf interchange on Interstate 83 north. The control points of Interstate 81 reflect a PENNDOT convention of in-state control cities. Carlisle is a southwest suburb of Harrisburg while Hazelton rests just south of the Interstate 80/81 junction. This same kind of concept can be found throughout the Interstate 80 routing within the Commonwealth. Photo taken by Tim Reichard (08/19/02).
Interstate 81/U.S. 322 and Interstate 78 overheads on Interstate 83 northbound approaching the northern end. This is the only remaining panel that includes Interstate 78 on Interstate 81 northbound. The east-west corridor links the Harrisburg metro area with Allentown-Bethelem, and ultimately New York City. Photo taken 07/00.
Approaching the northern terminus of Interstate 83, with U.S. 322 directional signage to the left, and a portable construction variable message sign to the right. Construction at this interchange is in conjunction with a resurfacing project associated with Interstate 81 in the northern Harrisburg area. Photo taken 10/01.
The end of Interstate 83 at Interstate 81 as seen from Interstate 83 Northbound. U.S. 322 continues westward along Interstate 81 south three miles. Photo taken 10/01.
Focusing on the Interstate 81/Exit 51 overheads on Interstate 83 north at the terminus. The control city of Allentown comes into play due to the connection with nearby Interstate 78 (situated 19 miles to the east). Lewiston is the western control point for U.S. 322 (and U.S. 22), well northwest of the city. Photo taken by Tim Reichard (08/19/02).
Interstate 81/83 stack interchange as seen from the northbound Interstate 83 to southbound Interstate 81 ramp. Photo taken 10/01.
Perspective from Interstate 81 north
Amid reconstruction, Interstate 81 northbound plods along towards the southbound beginning of Interstate 83. U.S. 322 is along for the ride at this point, but parts ways with Interstate 81 southward with Interstate 83. The Progress Avenue off-ramp is closed from Interstate 81 north/U.S. 322 east. Top photo taken by Tim Reichard (08/19/02); bottom photo taken by Dan Moraseski (09/02/02).
The damaged right-panel contains the control cites of Hershey and York for Interstate 83 south/U.S. 322 east. Although neither sign reflects it in these photographs, this tri-level stack interchange is Exit 70 for Interstate 81. Top photo taken by Tim Reichard (08/19/02); bottom photo taken by Dan Moraseski (09/02/02).
Perspective from Interstate 81 south

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-hand ramp of Exit 15.4
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
