MD 28 continues through the West Montgomery Avenue Historic District as a two-lane road with center turn lane. At Great Falls Road, near the Beall-Dawson House, the state highway veers southeast onto four-lane Jefferson Street through the Montgomery County Courthouse Historic District along the southern edge of downtown Rockville. MD 28 becomes a divided highway and its name changes to Veirs Mill Road at Monroe Street shortly before its oblique intersection with MD 355 (Rockville Pike) to the north of Richard Montgomery High School. Access from eastbound MD 28 to northbound MD 355 is provided via Monroe Street; the movement from westbound MD 28 to southbound MD 355 can be made via MD 660 (Dodge Street). After MD 28 crosses the Metropolitan Subdivision rail line and the Red Line of the Washington Metro, ramps to Stonestreet Avenue join eastbound and leave westbound to provide access to the Rockville station serving Metro, MARC, and Amtrak trains. East of the Stonestreet ramps, the state highway has a four-way intersection with MD 586 (Veirs Mill Road) and MD 911 (First Street); the latter route provides another connection between MD 355 and both MD 28 and MD 586.
