Maryland Route 103 (MD 103) is a state highway in the U.S. state of Maryland. The state highway runs 8.29 miles (13.34 km) from Parkway Drive South in Hanover northwest to St. Johns Lane in Ellicott City. MD 103 serves as the local complement to MD 100 from Hanover in northwestern Anne Arundel County through Dorsey to Ellicott City in northeastern Howard County. The state highway was constructed from U.S. Route 1 in Elkridge to US 29 in Ellicott City in the 1920s. MD 103's eastern terminus was relocated from Elkridge to US 1 near Dorsey in 1956. When MD 100 was constructed between Glen Burnie and Ellicott City in the 1990s, the state highway was extended to its present western and eastern termini. East of US 1, MD 103 replaced MD 176 east to near the Baltimore–Washington Parkway.

MD 103 begins 0.20 miles (0.32 km) east of Race Road in a business park adjacent to MD 100's interchange with the Baltimore–Washington Parkway in Hanover. The state highway heads northwest as two-lane Parkway Drive South, which begins to parallel the eastbound side of MD 100. MD 103's name changes to Dorsey Road at its intersection with Coca Cola Drive, which is unsigned MD 100M and has an interchange with MD 100 immediately to the north. The state highway curves away from MD 100, crosses a branch of Deep Run, and passes through the community of Dorsey, where the highway enters Howard County by passing under CSX's Capital Subdivision.[1][2]
MD 103 crosses Deep Run again and intersects Douglas Legum Drive, which leads to the Dorsey station on MARC's Camden Line. The state highway curves southwest and back to the northwest before its intersection with US 1 (Washington Boulevard). The highway is part of the National Highway System from US 1 east to Douglas Legum Drive as an intermodal connector to the Dorsey MARC station.[3] MD 103 continues northwest as Meadowridge Road, which passes between Meadow Ridge Memorial Park on the north and an industrial park to the south before passing under Interstate 95 (I-95) with no access. The state highway meets MD 100 at a dumbbell interchange. At Miller's Corner north of MD 100, MD 103 intersects its old alignment, Montgomery Road, which heads east toward Elkridge.[1][2]
MD 103 continues north as Montgomery Road and intersects Ilchester Road. Ilchester Road heads east to the hamlet of Ilchester on the Patapsco River, where the county highway provides access to Patapsco Valley State Park and the ruins of the Baltimore & Ohio Railroad's Patterson Viaduct. MD 103 continues northwest into Ellicott City, where the state highway meets the northern end of MD 104 (Waterloo Road). North of New Cut Road, the state highway expands to a four-lane undivided highway and intersects Long Gate Parkway, which provides access to eastbound MD 100, and Old Columbia Pike, which heads northeast into the Ellicott City Historic District. Just west of Old Columbia Pike, MD 103 has a partial diamond interchange with US 29 (Columbia Pike), where the highway's name changes to St. Johns Lane. Access from northbound US 29 to MD 103 is provided via MD 100 and Long Gate Parkway. MD 103 reaches its western terminus just west of its intersection with High Point Road. St. Johns Lane continues west to Columbia Road, where the county highway turns north toward US 40.[1][2]
MD 103 originally followed all of Montgomery Road from US 1 in Elkridge, which followed Old Washington Road, to US 29 (Old Columbia Pike) in Ellicott City.[4] The first section of MD 103 was paved in concrete from US 1 to west of Landing Road by 1923.[5] The next section was constructed as a concrete road from there west to the highway's intersection with Meadowridge Road at Miller's Corner in 1924 and 1925.[6][7] A disjoint section of MD 103 was built from US 29 east to near New Cut Road in 1928.[8] Montgomery Road was completed from near New Cut Road east to Miller's Corner by 1930.[9]
The portion of MD 103 east of US 1 was originally part of MD 176, which was completed as a concrete road from Glen Burnie west to the B&O Railroad in Dorsey on the Howard–Anne Arundel county line by 1930.[9] The portion between the county line and US 1 was constructed around 1936; MD 176 originally met US 1 at an intersection just south of the modern US 1–MD 100 interchange.[10] The Howard County portion of MD 176 was widened in 1949. MD 103 was widened from US 1 to Waterloo Road, which was then part of MD 175, in 1950.[11] The state highway was widened from Waterloo Road to US 29 starting in 1953.[12] In 1956, MD 103 was removed from Montgomery Road from Miller's Corner to Elkridge and instead placed on Meadowridge Road from Miller's Corner to US 1 near Dorsey.[13]
Several changes occurred in the route of MD 103 due to the construction of MD 100 in the 1990s. MD 103 was extended to its present western terminus when its interchange with US 29 was built in 1992.[14][15] The western end of MD 176 was relocated to the double-curve alignment in Dorsey to tie into the eastern end of MD 103 by 1995. MD 176 was cut in two when MD 100 took over the former highway's interchange with the Baltimore–Washington Parkway.[16] By 1997, MD 103 replaced MD 176 on Dorsey Road west of the parkway. That same year, the intersection of Montgomery Road and Meadowridge Road was reconstructed to make MD 103 the through route instead of Montgomery Road.[17] MD 103's interchange with MD 100 was completed in 1998 when MD 100 opened from MD 104 to I-95.[18][19]
