Maryland Route 190, or River Road, is a major state highway through southern Montgomery County, Maryland, United States.

Route description

MD 190 begins at MD 112's western terminus in Seneca, and ends at the Montgomery County/Washington, D.C. border. Inside the District of Columbia, River Road continues (with that name, but not the route number) to Wisconsin Avenue.

The route is named River Road because it parallels the Potomac River for most of its course, although the name extends past where MD 190 actually terminates in both directions. MD 190 goes through a few populated areas such as Potomac, Maryland and other suburban areas near DC. It intersects with the Capital Beltway and the Cabin John Parkway about halfway between Potomac Village and DC, at exit 39 on the Beltway. Traffic from Interstate 270 to Washington may use MD 190.

There are many parks along MD 190, including the C&O Canal National Historical Park, McKee-Beshers Wildlife Management Area, and Blockhouse Point Conservation Park, among others.

2008 water main break

On Tuesday, December 23, 2008, during the morning rush hour, a 66-inch (1,700 mm) water main ruptured along MD 190 near its intersection with Bradley Blvd., causing a major flood along the roadway. Many vehicles were trapped in the water, and a number of individuals had to be rescued by boat or helicopter.^[2]
