U.S. Route 301 (Maryland) is a north–south United States Numbered Highway that runs through the eastern part of Maryland, connecting the Washington metropolitan area via the Nice Bridge with the Delmarva Peninsula and the Delaware Bay corridor, terminating at the state line near Smyrna. The route serves as a major freight and passenger arterial, intersecting with interstates and state routes such as I‑95, I‑295, US 50, and MD 404, and traverses a mix of suburban, rural, and coastal landscapes across counties including Charles and Queen Anne's.
Route description
US 301 enters Maryland from Virginia on the Nice Bridge over the Potomac River, continuing north into Charles County toward Waldorf, where it meets MD 5, MD 228, and links to I‑95 via MD 4 and MD 210. Proceeding northeast, the highway crosses into Prince George's County near Upper Marlboro and connects with US 50 and MD 50 feeders that serve Annapolis and BWI Airport. Continuing through Anne Arundel County it intersects I‑97 and provides access to Fort Meade and NSA employment centers via MD 175.
North of Queen Anne's County and Centreville, US 301 becomes a four-lane divided highway that parallels Chesapeake Bay, meeting MD 404 at a major junction that serves Ocean City traffic and links to DE 1. It then traverses Caroline County and Kent County agricultural areas, intersecting MD 213 near Chestertown and MD 213 connectors to Salisbury. Approaching the northeast corner of Maryland, US 301 passes through Cecil County near Elkton before crossing the state line toward Delaware.
History
The corridor now designated US 301 follows alignments historically used by colonial roads connecting Alexandria and Philadelphia and later by 20th‑century auto trails such as the Lincoln Highway and regional routes serving Baltimore and Wilmington. US 301 was extended into Maryland in the 1930s as part of the national numbering system created by the AASHO and was realigned several times in response to growth in Washington suburbs and the rise of truck traffic between the Mid‑Atlantic states.
Major improvements include the construction of the Nice Bridge replacement projects overseen by the MDOT and coordination with the FHWA. The development of four‑lane bypasses around towns such as Waldorf, Denton, and Elkton corresponded with postwar suburbanization linked to I‑95 and the Interstate Highway System. Environmental reviews and permits involving the USFWS and the MDE shaped routing decisions near wetlands and the Chesapeake Bay watershed. Notable legal and legislative actions affecting US 301 include state transportation bond acts and congressional appropriations tied to NEPA reviews.
Major intersections
Significant junctions along US 301 include its southern link at the Nice Bridge connecting to VA 3 and US 301 (VA), interchanges with MD 5 and MD 228 in Charles County, connections to I‑295 and I‑495 approaches serving Washington, and an interchange with US 50/MD 50 east of Annapolis. Further north, junctions with MD 404 provide access to Ocean City, while intersections with MD 213 and MD 290 serve Chestertown and Rock Hall. Near the state line, US 301 links with regional arterials serving Elkton, Newark, and Smyrna before continuing as DE 1 into Delaware.
Future and planned improvements
MDOT and regional planning agencies including the MWCOG and the DelDOT have studied capacity and safety enhancements for US 301, focusing on interchange upgrades at MD 404 and corridor widening between Queen Anne's and Cecil County. Projects under consideration involve coordination with the FHWA, funding from the TIFIA, and compliance with the Clean Water Act and ESA when work affects the Chesapeake Bay watershed and habitat for species overseen by the USFWS. Freight movement initiatives link US 301 improvements to the National Highway Freight Network and planning by the FHWA and USDOT to enhance intermodal connections with ports such as the Port of Baltimore.
Auxiliary routes and related highways
Associated routes and related highways include concurrent and connecting segments with US 50, MD 404, MD 213, and spurs linking to MD 290 and MD 312. Historic alignments and bypassed sections remain as state and county roads, some managed by SHA and county governments such as Caroline County and Queen Anne's County. Regional coordination involves agencies including MDOT, DelDOT, and metropolitan bodies like MWCOG.
