Interstate 83 (abbreviated I-83) is an Interstate Highway in the eastern United States. Its southern terminus is in Baltimore, Maryland at the Fayette Street exit; its northern terminus is in Harrisburg, Pennsylvania at Interstate 81.

Most of the route south of Lemoyne, Pennsylvania is a direct replacement of US 111, a former spur of US 11.

Jones Falls Expressway

Interstate 83 begins its northern trek at Fayette St. in downtown Baltimore, east of the central business district. Originally planned to continue south of Fayette St. to Interstate 95 north of the Fort McHenry Tunnel, the route was truncated in late 1982 and now ends at Fayette St. The highway south of the intersection turns into President St., a wide boulevard that collects and distributes traffic from and to the local streets in the area.

Starting at Fayette St., I-83 is an elevated four- and six-lane freeway, known locally as the Jones Falls Expressway or JFX, that parallels Maryland Route 25 Falls Road and its namesake river, the Jones Falls, which flows near and (mostly on the southern end) directly beneath the freeway. Both I-83 and MD 25 follow a similar path out of the city centre, passing beneath US 40 Orleans St. with no access and interchanging with Maryland Route 2 and US 1 north of the CBD. Beyond US 1, the JFX is also paralleled by the Baltimore Light Rail system.

After exiting Baltimore, the JFX continues north and eventually reaches Interstate 695, the Baltimore Beltway. I-83 separates from the JFX, which runs beyond the Beltway and terminates at MD 25, and joins I-695 for 1.4 miles (2.3 km); recent construction work widened the concurrency between the two Interstates to ten lanes. I-83 and I-695 split off at the southern terminus of the Baltimore-Harrisburg Expressway, and I-695 continues its eastward trek towards Towson and Parkville.

Baltimore-Harrisburg Expressway

After separating from the Beltway, I-83 is now known as the Baltimore-Harrisburg Expressway. Running due north away from the Beltway, the route parallels Maryland Route 45 York Road, the former route of US 111. Passing to the west of Timonium and Cockeysville, I-83 leaves the suburban belt around Baltimore and enters rural Baltimore County just north of Hunt Valley at Shawan Road. I-83 and MD 45 continue to parallel one another through the northern portion of the county, with both crossing over each other repeatedly. This segment of I-83 has several sections with higher than usual gradients.

The only major settlement encountered by I-83 along this stretch is Monkton, reached via Maryland Route 137. To the west of I-83, MD 137 connects with the northern terminus of MD 25, I-83's former companion to the south.

The Interstate eventually crosses the Mason-Dixon Line, York County, Pennsylvania after the 35th exit into Pennsylvania 25 miles (40 km) north of Baltimore, mere feet from a partial interchange with Freeland Road and parallel with MD 45; the latter route becomes the Susquehanna Trail on the other side of the line.


I-83 enters Pennsylvania southeast of New Freedom, passing to the east of Shrewsbury and running due north towards York. The route bypasses the villages of Loganville and Jacobus before entering the city of York.

Uniquely for an Interstate near the east coast, I-83 has a business route through downtown York, known as Interstate 83 Business. The business route follows the former path of US 111, while I-83 turns northeast and then north again to bypass the urban area. Near US 30 Lincoln Highway, the Interstate turns west for a short distance, then north again to interchange with the U.S. route. Beyond US 30, I-83 resumes its straight path, running due north out of York and passing to the west of Emigsville.

North of Pennsylvania Route 295, I-83 is known as the Susquehanna Expressway. It maintains this name as it passes to the south and west of Valley Green, continuing north towards Harrisburg. South of Harrisburg, I-83 interchanges with Interstate 76, the Pennsylvania Turnpike. North of I-76, I-83 continues due north, passing through New Cumberland, before merging with Pennsylvania Route 581 in Lemoyne.

After merging with PA 581, I-83 is known as the Harrisburg Expressway. The highway turns due east within the merge and crosses the Susquehanna River south of Harrisburg's central business district, passing through Paxtang before encountering Interstate 283 and US 322 at the Eisenhower Interchange. Within the interchange, I-83 exits from itself, with each direction of traffic following a one-lane ramp; I-83's former mainline carriageways become US 322, while I-283's former mainline carriageways become I-83. The interchanges includes ramps to local city streets as well. From this point northbound to exit 51 traffic is often congested during daylight hours.

Beyond this interchange, I-83 runs due north again through eastern Harrisburg, interchanging with US 22 northeast of the central business district, before terminating at a three-way semi-directional interchange with Interstate 81.


Interstate 83 (JFX) southbound in Baltimore

Jones Falls Expressway

The first Interstate to be built in Baltimore was the Jones Falls Expressway; it was the first to be constructed due to community opposition to the other planned freeways within the city. By the early 1960s, the JFX was completed as far as Guilford Ave, within the city limits. It was completed as far as Pleasant St. in the downtown area by 1983, with the cancellation of the remaining 4.4 miles (7.1 km) to Interstate 95 being undertaken in September 1982. To compensate for the loss of the remainder of the JFX, the portion in situ was extended to Fayette St. by 1987, and the Jones Falls Boulevard project substantially rebuilt 3/4 of a mile of President St., across from the JFX at Fayette St., to allow the traffic to and from the Interstate to be collected and distributed from the surrounding city streets. By 1990, the project was completed.


As Congress worked toward reauthorization of the Surface Transportation Act, the Greater Lynchburg Chamber of Commerce and other groups in Virginia wanted Interstate 83 extended southward to provide bypasses for Charlottesville, Lynchburg, and Danville, and to link those cities to Greensboro, North Carolina. By June 1991, Robert LaLone, director of programs for the Lynchburg Chamber, admitted that an interstate was unlikely, but upgrading of U.S. Highway 29, with bypasses included, is more likely.[2]

The possibility of extending I-83 north to Rochester, New York instead of I-99 was discussed at the October 2002 I-99 Task Force meeting. However, part of the proposed route on US 11/US 15 has been recently rebuilt as a four lane surface road that does not meet Interstate standards.[3] Expensive additional reconstruction, including new interchanges, service roads and realignments, would be necessary. The farthest north that I-83 could be extended currently would be Benvenue, Pennsylvania on a bridge over the Susquehanna River, where a recently built freeway section of US 22/US 322 (the Dauphin Bypass) downgrades to an undivided four-lane road.

Business routes

Business loop of York, Pennsylvania

Interstate 83 Business
Location York, Pennsylvania
Existed 1957–present

Interstate 83 Business is a short Interstate business loop in York, Pennsylvania. Its northern terminus is at I-83 and Pennsylvania Route 181 north of York. Its southern terminus is at I-83, south of York. The road is known as George Street for much of its length.

I-83 Business is the only business route of I-83 and was the only Interstate business route in the entire state of Pennsylvania, although this changed in 2009 when Pennsylvania Route 60 Business in Moon Township, Pennsylvania, near Pittsburgh became signed as I-376 Business[4] when the current alignment of PA 60 itself became an extension of I-376. The route was constructed in 1958 but signed in 1957. I-83 Business goes through downtown York on George Street, the main north–south artery of the city.
