Maryland Route 108 (MD 108) is a state highway in the U.S. state of Maryland. The highway runs 34.23 miles (55.09 km) from MD 27 in Damascus east to MD 175 in Columbia. MD 108 is an S-shaped highway that winds through northern Montgomery County and central Howard County. The highway connects the Montgomery County communities of Laytonsville, Olney, Sandy Spring, and Ashton with the Howard County villages of Highland and Clarksville. MD 108 serves as the northern edge of Columbia and connects several of the planned community's suburban villages.
MD 108 originally connected Damascus with Olney. This highway was constructed between the mid-1920s and early 1930s. MD 108 from Olney to Columbia, part of Clarksville Pike, was originally constructed as
Route description
MD 108 begins at a three-way intersection with MD 27 (Ridge Road) in the center of Damascus. The latter highway heads north and west from the intersection; MD 108 heads east as four-lane undivided Main Street. The street reduces to two lanes just east of Woodfield Road, which heads south as MD 124. MD 108's name changes to Damascus Road at Howard Chapel Road at the east end of the village. The highway heads southeast and meets the southern end of Annapolis Rock Road, which leads to MD 94 at the Montgomery–Howard county line. MD 108 meets the northern end of MD 650 (Damascus Road) in the hamlet of Etchison, where the highway turns south onto Laytonsville Road. The route intersects Brink Road and Sundown Road next to the Layton House in the center of the town of Laytonsville.[1][2]
MD 108 veers southeast out of Laytonsville and continues along Laytonsville Olney Road. The highway passes a pair of gold courses and the historic home
MD 108 leaves Ashton as two-lane undivided Ashton Road, which the route follows to the Montgomery–Howard county line at the

MD 108 is a part of the National Highway System as a principal arterial in three sections: from its western terminus at MD 27 in Damascus to Mullinix Mill Road; from Brookeville Road near Olney to MD 650 in Ashton; and from MD 216 at Highland to MD 32 in Clarksville.[1][3]
History
MD 108 originally extended from MD 27 in Damascus to MD 97 in Olney. Continuing east along what is today MD 108, as of 1939, route numbers assigned to the highway included MD 28 from Olney to Ashton; US 29 from Ashton to Columbia, which was then a hamlet at the site of the modern MD 108–US 29 interchange; a county highway from Columbia to Jonestown, a hamlet at the site of the modern MD 108–MD 104 intersection; and MD 531 from Jonestown to west of Waterloo, a village at the intersection of US 1 and MD 175.[4] The US 29 segment was originally designated MD 27 in 1927; the original highway numbered MD 29 was what is today MD 27.[5] When US 29 was extended into Maryland in 1934, the routes swapped numbers to their present designations.[6] By 1946, MD 108 was extended east to Ashton when MD 28 was truncated at MD 97 at Norbeck. In addition, MD 531 was replaced by an extension of MD 175.[7]
The first segment of MD 108 was built by Montgomery County with state aid from Brink Road south to Warfield Road in the town of Laytonsville by 1910. This segment was part of a macadam road from Laytonsville south toward Gaithersburg that later became part of MD 124.[4][8] The next segment of MD 108 was a 0.5-mile (0.80 km) stretch of concrete road north from Brink Road in Laytonsville completed in 1923.[9] Another piece of concrete road was built from the macadam road in Laytonsville southeast to Riggs Road at Claysville between 1925 and 1927.[10][5] The concrete road on the north side of Laytonsville was extended north to near Etchison between 1926 and 1928.[10][11] Another section of MD 108 was started from MD 29 in Damascus in 1927; the highway from Laytonsville to Damascus via Etchison was completed in 1929.[12][10][13] In addition, the concrete road southeast from Laytonsville was extended to Brookeville Road and a new segment was constructed west from MD 97 to Bowie Mill Road in Olney.[13] The final segment of MD 108 between Laytonsville and Olney was started in 1930 and completed by 1933.[14][15]
The highway from Olney to Columbia was proposed as one of the original state highways by the

MD 531 was constructed as a macadam road from Waterloo to Jonestown in 1932.[19][15] MD 175 was relocated, widened, and resurfaced along old MD 531 from Waterloo to Jonestown in 1954.[20] Old Annapolis Road from Columbia to Jonestown was brought into the state highway system as MD 539 in 1956.[21] The new Columbia Pike from Columbia south to White Oak was complete in 1958 but did not become part of US 29 until 1960.[22][23] Old US 29 from White Oak to Ashton was renumbered MD 650; MD 108 was extended east along old US 29 from Ashton to Columbia and along MD 539 to MD 175 at Jonestown.[23] MD 175 was relocated to its and MD 108's present divided highway west of I-95 in 1969 in conjunction with the construction of the I-95–MD 175 interchange between then and 1971.[24][25] When MD 175 was relocated to its present alignment through Columbia in 1977, MD 108 was extended along old MD 175 to its present eastern terminus.[26] MD 108 was expanded to a four-lane divided highway on either side of US 29 in conjunction with the construction of the interchange in 1987 and 1988.[27][28] The state highway was expanded to a four-lane divided highway through Olney in 1994.[29][30] MD 108's interchange with MD 32 was built in 1996.[29][31] MD 108 was later widened at its intersection at Centennial Lane and Beaverbrook Road from the middle of 2021 to early 2023.[32]
