The unsigned highway runs 1.86 miles (2.99 km) from MD 28 east and south to Carrolton Road in the Norbeck area of eastern Montgomery County.

The route follows what were two of the original state roads constructed in the early 1910s.

The highway heads east as Old MD 28, a one-lane road that closely parallels the eastbound direction of MD 28, with the two roads separated by a row of trees.

There, the highway turns south to parallel the southbound lanes of MD 97 (Georgia Avenue), separated by two rows of trees.

The roadway continues beyond a guardrail that restricts traffic to the three houses beyond before the pavement ends just north of Bel Pre Road.

[3] Norbeck Road from the old turnpike west toward Rockville was under construction in 1911 and completed in 1912.
