History

The corridor that Old Germantown Road occupies traces back to colonial-era paths and nineteenth-century turnpikes used by communities that later evolved into Rockville, Maryland and Gaithersburg, Maryland. In the late 1800s the route served agricultural markets connected to railheads associated with Baltimore and Ohio Railroad and the growth of regional nodes connected to Washington, D.C.. During the twentieth century, state designation and improvements followed patterns set by agencies including Maryland State Highway Administration and planners influenced by reports from entities like the National Capital Planning Commission. Postwar suburban expansion linked to developers such as Kingdon Gould, Jr. and William Levitt-era influences drove widening projects and intersection reconstructions. Late twentieth- and early twenty-first-century improvements responded to commuter demand from high-tech employment centers including companies like Lockheed Martin, Boeing, and regional campuses of NIH and FDA.

Major intersections

Key junctions include Maryland Route 355 near Rockville, Maryland, connections to Interstate 270 in Maryland interchange ramps, crossings with Maryland Route 28 and local thoroughfares feeding Gaithersburg, Maryland developments such as Midcounty Regional Services Center. These intersections link to transit hubs associated with Washington Metropolitan Area Transit Authority stations and park-and-ride facilities used by services like Montgomery County Ride On and commuter operators including MARC Train feeders. Nearby municipal boundaries involve jurisdictions like Montgomery County, Maryland and partnerships with agencies such as Maryland Transit Administration for multimodal integration.

Traffic and usage
