Maryland Route 28 (MD 28) is a state highway in the U.S. state of Maryland. The state highway runs 37.38 miles (60.16 km) from U.S. Route 15 (US 15) in Point of Rocks east to MD 182 in Norwood. The western portion of MD 28 is a rural highway connecting several villages in southern Frederick County and western Montgomery County. By contrast, the eastern portion of the state highway is a major east–west commuter route, particularly within Gaithersburg and Rockville.
MD 28 was an original 1927 Maryland state highway. The state highway originally extended north and east through Olney to Ashton, but the highway was rolled back to Norbeck in the 1940s. MD 28 was extended east to its present eastern terminus in the early 1980s. The original western terminus was in Tuscarora, but the state highway was extended to Point of Rocks around 1970. In addition to being expanded to a multi-lane divided highway in central Montgomery County beginning in the 1970s, MD 28 was relocated in downtown Rockville in the 1940s, in eastern Rockville in the 1970s, and in western Rockville in the 1990s.
