After leaving the town limits of Kensington, MD 185 becomes a six-lane controlled access divided highway passing between residential subdivisions. After crossing a tributary of Rock Creek, the state highway intersects MD 586 at an acute intersection. MD 185 then becomes lined with service roads ahead of and after the intersection with Randolph Road. Beyond Weller Road, the state highway crosses Turkey Branch and then a bridge over Matthew Henson State Park. MD 185 then enters Aspen Hill and intersects Aspen Hill Road within a commercial area. The state highway meets its northern terminus at MD 97 (Georgia Avenue). Connecticut Avenue continues as a county-maintained highway north across Bel Pre Road into Rossmoor, home of the Leisure World retirement community.
