The highway runs 2.53 miles (4.07 km) from Summit Avenue in Kensington east to MD 97 in Forest Glen in Montgomery County.

MD 192 begins on Plyers Mill Road at its intersection with Summit Avenue in the town of Kensington.

[1][2] MD 192 continues southeast and approaches the tracks again before passing through a very sharp S-curve before the Forest Glen Castle.

There, the highway has a four-way intersection with Seminary Road, which continues southeast across I-495 (Capital Beltway), and Linden Lane, which heads southwest across an at-grade crossing of the rail line toward the redeveloped National Park Seminary and the U.S. Army's Forest Glen Annex.

The route expands to a four-lane divided highway at Darcy Forest Drive and passes the Forest Glen Metro station before reaching its eastern terminus at MD 97 (Georgia Avenue) just north of that highway's interchange with the Capital Beltway.

[6][11] This middle segment between Sligo Creek Parkway and Dallas Avenue was transferred to Montgomery County by 1961.
