U.S. Route 220 (Maryland) is a short federal highway segment located in Allegany County connecting the Mason–Dixon line at the Pennsylvania–Maryland border to Interstate 68 near Cumberland. The route functions as a regional connector between Pennsylvania corridors and the National Road/Interstate 68 corridor, providing access to regional nodes including Allegany College of Maryland, Western Maryland Rail Trail, and the Potomac River. U.S. Route 220's Maryland alignment is notable for its short length, proximity to historic sites, and role in interstate freight and commuter movements connecting to I-70, I-81, and the broader United States Numbered Highway System.
U.S. Route 220 enters Maryland from Pennsylvania at the Mason–Dixon line and proceeds southward into Allegany County, intersecting local arteries that serve Cumberland, Frostburg, and rural communities. The highway parallels sections of the Western Maryland Scenic Railroad and crosses terrain associated with the Allegheny Mountains, skirting the Potomac River watershed before meeting an interchange with Interstate 68 near the Narrows of the region. Along its course the route is proximate to landmarks such as Fort Cumberland, the C&O Canal National Historical Park, and regional institutions like Western Maryland Health System and Allegany County Public Schools. Traffic composition includes commuter flows to Cumberland employment centers, as well as freight movements linked to connections toward Interstate 70 and Interstate 81 via connecting highways.
The alignment now designated as U.S. Route 220 in Maryland evolved from 19th-century turnpikes and early 20th-century state roads that linked Cumberland with Pennsylvania and the greater National Road network. During the creation of the United States Numbered Highway System in the 1920s, U.S. Route 220 was designated to provide a north–south trunk between Rocky Mount, North Carolina, Martinsburg, West Virginia, and Williamsport, Pennsylvania, with the Maryland segment formalized to connect with the Mason–Dixon line crossing. Postwar improvements and the advent of the Interstate Highway System prompted construction of interchanges linking U.S. Route 220 to I-68 and upgrades near industrial sites such as the Cumberland Terminal and freight yards used by CSX Transportation. Preservation efforts around nearby historic sites, including Fort Cumberland and the Allegheny Highlands, have influenced roadway design and right-of-way decisions, balancing mobility with heritage conservation initiatives led by organizations like the National Park Service.
- At the Mason–Dixon line — continuation to Pennsylvania routes and local connectors toward Bedford County and Somerset County. - Local arterial junctions providing access to Cumberland municipal streets, Allegany County facilities, and regional hospitals such as Western Maryland Regional Medical Center. - Interchange with Interstate 68 / U.S. Route 40 — primary connection west toward I-70/Hagerstown and east toward Frostburg and Hancock.
Planned improvements affecting U.S. Route 220 in Maryland have been discussed in regional transportation planning forums involving the Maryland Department of Transportation, Allegany County Government, and metropolitan planning organizations that coordinate with Federal Highway Administration programs. Proposals have included safety upgrades informed by traffic studies referencing crash data similar to analyses used for corridors such as US 219 and interchange enhancements to improve connectivity with I-68 and freight routes used by CSX Transportation and regional trucking firms. Environmental review processes coordinate with National Park Service stewardship of adjacent parklands like the C&O Canal National Historical Park and watershed protection initiatives tied to the Potomac River Basin, while funding discussions consider federal aid modeled on Transportation Equity Act for the 21st Century precedents and state capital improvement plans.
