Maryland Route 129 is a state highway in the U.S. state of Maryland, running north-northwesterly from downtown Baltimore into Baltimore County, ending east of Reisterstown.

Route description

Baltimore City

Maryland Route 129, in Baltimore City, passes through or near many historic neighborhoods. These include Upton, Bolton Hill, Reservoir Hill, Pimlico, and Park Heights. The route is mostly lined with rowhouses until it reaches Upper Park Heights, an area known for its single-family homes, duplexes, and luxury apartments and condos. (Fallstaff, Baltimore)

Park Heights Avenue is also one of the boundaries of the famous Pimlico Race Course, home of the Preakness Stakes.

The entire route throughout Baltimore City has at least two travel lanes in each direction and parallel parking in most locations. For a short distance while passing Druid Hill Park, route 129 overlaps with Maryland Route 140, also known as Reisterstown Road.

Baltimore County

When Maryland Route 129 reaches the city/county line after Seven Mile Lane then at Slade Avenue, the road narrows into one travel lane in each direction, plus occasional turn lanes. From this point until its terminus at Garrison Forest Road in Owings Mills, the road is lined with upscale communities and undeveloped land.

The route intersects with the Interstate 695, also known as the Baltimore Beltway, about one mile (1.6 km) north of the city line.
