the designation for a pair of highways near MD 118 in Germantown in northern Montgomery County. The designation was first applied to Waters Road from MD 118 at the Baltimore and Ohio Railroad north to the site of what is now I-270. MD 120 was paved as a macadam road from MD 118 along the portion of Waters Road that still exists in Germantown and as a concrete road northeast from there in 1930. By 1978, MD 120 existed in two segments: the extant portion of Waters Road, and an L-shaped portion closer to I-270 that included Aircraft Drive northwest from MD 118 parallel to I-270 and a road that no longer exists heading northeast from the end of Aircraft Drive to a dead end at I-270. The road from the end of Aircraft Drive was removed from the state highway system in 1981. Both remaining segments of MD 120 were removed from the state highway system in 1999 as part of the highway swap to designate the Great Seneca Highway as MD 119. MD 122 Maryland Route 122 was the designation for Bethesda Church Road from MD 27 in Damascus west to Clarksburg Road in northern Montgomery County. The highway was constructed as a concrete road from the original MD 29 (now MD 27) west to beyond MD 123 (Johnson Drive) between 1924 and 1926. MD 122 was extended as a macadam road to Clarksburg Road in the village of Browningsville in 1929 and 1930. The highway was removed from the state highway system in 1974. MD 123 Maryland Route 123 was the designation for a highway that followed what are today Lewisdale Road, Clarksburg Road, Prices Distillery Road, Mountain View Road, and Johnson Lane from MD 75 near Hyattstown east to MD 122 near Damascus in northern Montgomery County and the southeastern edge of Frederick County. A very short piece of concrete road was built west from MD 122 by 1927. MD 123 was extended as a macadam road to Burnt Hill Road in the hamlet of Purdum and as a concrete road from there to Lewisdale Road by 1930. The highway was extended to Clarksburg Road in the village of Lewisdale in 1933 and 1934. MD 123 was extended west to MD 75 by 1946. The Frederick County portion of the highway was transferred to county control by 1961. The Montgomery County section of MD 123 was
