Maryland Route 28

Maryland Route 28 is a state highway in the U.S. state of Maryland that runs across western and central Montgomery County and eastern Frederick County. The highway connects Point of Rocks, Maryland and Rockville, Maryland, passing through communities such as Brunswick, Maryland, Ivyland? and Gaithersburg, Maryland while intersecting major corridors like Interstate 270, U.S. Route 15, and U.S. Route 340. It provides a link between historic river crossings on the Potomac River and suburban centers near Washington, D.C. and serves both commuter and local traffic.

Route description

Maryland Route 28 begins near the Potomac River at an interchange with U.S. Route 15 and the Potomac River crossing in the vicinity of Point of Rocks, Maryland and proceeds eastward through Frederick County toward Brunswick, Maryland. The route intersects U.S. Route 340 and provides access to the C&O Canal National Historical Park and the Brunswick Historic District before entering Montgomery County. Through Montgomery County the highway passes near Clarksburg, Maryland, Gaithersburg, Maryland, and Rockville, Maryland while intersecting Interstate 270, MD 355, and other arterial roads that connect to Bethesda, Maryland, Silver Spring, Maryland, and the I-495. The corridor traverses suburban commercial zones, residential neighborhoods, and preserved natural areas such as sections adjacent to the Monocacy National Battlefield and other protected landscapes. Roadway characteristics change from two-lane rural segments in Frederick County to multilane suburban sections with traffic signals and turn lanes approaching Montgomery County Civic Center and downtown Rockville, Maryland.

History

The alignment that became the state highway was part of early 20th-century improvements linking Frederick, Maryland area communities to emerging automobile routes and river crossings at Point of Rocks. The route received its current numeric designation in 1927 during statewide renumbering efforts that coincided with the establishment of routes like U.S. Route 15 and the expansion of the U.S. Numbered Highway System. Over the decades, the highway was realigned, widened, and bypassed in sections to accommodate traffic growth associated with suburbanization driven by the expansion of Washington Metro-area employment centers and the construction of I-270. Notable historical developments include construction of grade separations near major intersections influenced by planning initiatives from agencies including the Maryland State Highway Administration and coordination with county planning departments in Frederick County and Montgomery County. Preservation efforts around the Chesapeake and Ohio Canal National Historical Park and the Brunswick Historic District shaped routing choices to balance transportation needs and heritage conservation. Incremental upgrades paralleled regional projects such as improvements to US 15 and the creation of interchanges serving commuter flows to Washington, D.C. and employment centers like Bethesda, Maryland and Rockville, Maryland.

Major intersections

The highway meets several principal corridors and municipal gateways along its length. Key junctions include the western terminus near Point of Rocks, Maryland with US 15 and connections to facilities serving the Potomac River crossing; an intersection with US 340 providing access to Harper's Ferry-area routes; crossings and interchanges with county and state arterials that lead to Brunswick, Maryland, Frederick, Maryland, Gaithersburg, Maryland, and Clarksburg, Maryland; a major interchange with I-270 linking to I-495 and the Capital Beltway network; and the eastern terminus in Rockville, Maryland connecting with urban streets that intersect MD 355 and provide access to transit hubs serving Washington Metro Red Line stations and regional bus services. These intersections create multimodal connections for commuters, freight, and local traffic between historic towns and suburban nodes.

Future improvements

Planned and proposed improvements have focused on congestion mitigation, safety enhancements, and multimodal connectivity coordinated by the Maryland Department of Transportation and local planning bodies in Montgomery County and Frederick County. Projects under consideration include capacity upgrades near growing suburban centers such as Gaithersburg, Maryland and Clarksburg, Maryland, intersection reconfigurations to improve access to I-270 and US 15, and pedestrian and bicycle facility additions to link with regional trails like the C&O Canal towpath and county trail networks. Funding priorities reflect coordination with regional transit and land-use planning involving entities such as the Metropolitan Washington Council of Governments and local municipal governments in Rockville, Maryland and Gaithersburg, Maryland.

Auxiliary routes

Auxiliary and related routes around the corridor include county-maintained connectors, short state-designated spurs, and business routes that serve downtown areas such as Brunswick, Maryland and industrial sites near Point of Rocks, Maryland. These auxiliary alignments provide access to historic districts, rail facilities like those on the Baltimore and Ohio Railroad corridor, and park-and-ride locations serving commuter traffic to Washington, D.C. and suburban employment centers. The network of auxiliary links is managed through collaboration between the Maryland State Highway Administration and county roadway agencies in Frederick County and Montgomery County.
