MD 28 is a state highway in the U.S. state of Maryland connecting communities across Montgomery County and into Frederick County. The route links suburban and rural corridors between Ridge and Colesville, intersecting major arteries such as Interstate 270, U.S. Route 29, and Maryland Route 97. MD 28 serves commuter, commercial, and historic travel, passing near landmarks like Sugarloaf Mountain and institutions including Montgomery College and United States Naval Observatory satellite facilities.

Route description

MD 28 begins in the west near Ridge and proceeds eastward through a mix of residential, agricultural, and commercial corridors. Early segments pass landmarks such as Catoctin Mountain Park outskirts, crossing near historic properties listed in the National Register of Historic Places in Maryland. The route intersects county and state roads that provide access to Frederick and suburban centers like Gaithersburg and Rockville. Eastbound lanes meet Interstate 270 with ramps providing connections to Washington, D.C. commuter traffic; nearby interchanges link with Maryland Route 117 and local collector streets serving Montgomery Village.

Continuing, MD 28 traverses commercial districts adjacent to Wheaton and residential neighborhoods abutting institutions such as Montgomery College satellite sites. The highway crosses waterways that feed into the Potomac River watershed and parallels sections of historic roads used during the American Revolutionary War and American Civil War. Near its eastern terminus, MD 28 meets U.S. Route 29 and connects to Maryland Route 97 before ending in Colesville, where local roads lead toward Silver Spring and Baltimore corridors.

History

Designated in the 1920s as part of Maryland's numbered system, MD 28 evolved as road-building accelerated statewide during the Automobile Club of America era and New Deal roadway projects. Early 20th-century improvements tied MD 28 to turnpikes and plank roads that linked Frederick County farms with markets in Washington, D.C. and Baltimore. Federal programs like the Federal-Aid Highway Act influenced upgrades that brought paving, widening, and realignment through the mid-20th century, particularly as suburbanization around Bethesda and Rockville expanded.

Postwar suburban growth prompted interchange constructions with Interstate 270 and capacity projects coordinated with agencies including the Maryland State Highway Administration and regional planners from the Metropolitan Washington Council of Governments. Preservationists linked segments of the corridor to historic preservation efforts related to sites such as Glen Echo Park and community activism in Sandy Spring. Late 20th- and early 21st-century projects emphasized traffic calming, multimodal access, and environmental mitigation influenced by legislation like the Clean Water Act.

Major intersections

The route connects several principal highways and local arterials that form the backbone of regional travel: - Western terminus near Ridge—local connectors toward Brunswick and Point of Rocks. - Junction with U.S. Route 15 corridor access via county roads serving Jefferson. - Interchange with Interstate 270 providing links to Gaithersburg and Rockville. - Intersection with Maryland Route 117 near suburban centers including Germantown. - Crossings of U.S. Route 29 and Maryland Route 97 approaching the eastern terminus near Colesville and access to Silver Spring.

Future

Planned and proposed projects affecting the corridor include capacity improvements, intersection upgrades, and multimodal enhancements coordinated by the Maryland Department of Transportation and regional bodies such as the Washington Metropolitan Area Transit Authority. Proposals explore bus rapid transit alignments that would interface with MD 28's corridor and transit-oriented development initiatives near major nodes like interchange areas for Interstate 270 and U.S. Route 29. Environmental reviews driven by the National Environmental Policy Act and county master plans for Montgomery County shape right-of-way modifications, stormwater management retrofits, and bicycle-pedestrian facilities that aim to integrate with nearby green spaces like Black Hill Regional Park and trails linked to Capital Crescent Trail.

Auxiliary routes

Several short connectors and spur roadways tie MD 28 to adjoining state and county routes. These auxiliary alignments include service roads and ramp connectors near major interchanges with Interstate 270 and U.S. Route 29, as well as legacy alignments that remain under county jurisdiction after realignments influenced by highway improvements. Coordination among the Maryland State Highway Administration, Montgomery County Department of Transportation, and local municipalities governs maintenance and transfer agreements for these auxiliary segments.

Tourist and scenic designations

Segments of the corridor are proximate to scenic and historic attractions such as Sugarloaf Mountain, cultural sites in Glen Echo, and preserved landscapes tied to the Catoctin Mountain Park. Wayfinding and heritage signage connect travelers to nearby destinations including Brookside Gardens, Kenilworth Aquatic Gardens, and historic districts listed in the National Register of Historic Places in Montgomery County. The route functions as a gateway for recreational access to regional parks and trails serving residents of Washington, D.C., Baltimore, and surrounding suburbs.
