Maryland Route 32 (MD 32) is a state highway in the U.S. state of Maryland. The road runs 51.79 miles (83.35 km) from Interstate 97 (I-97) and MD 3 in Millersville west and north to Washington Road in Westminster. The 30 mile four- to six-lane freeway portion of MD 32 is the Patuxent Freeway between I-97 and I-70 in West Friendship. The freeway passes through Odenton and Fort Meade, the site of Fort George G. Meade and the National Security Agency (NSA), in western Anne Arundel County and along the southern part of Columbia in Howard County. Via I-97, MD 32 connects those communities with U.S. Route 50 (US 50)/US 301 in Annapolis. MD 32 also intersects the four primary highways connecting Baltimore and Washington: the Baltimore–Washington Parkway, US 1, I-95, and US 29. MD 32's north–south section, Sykesville Road, connects West Friendship and Westminster by way of Sykesville and Eldersburg in southern Carroll County.
Maryland Route 31 is a state highway in the U.S. state of Maryland. Known for most of its length as New Windsor Road, the state highway runs 16.95 miles (27.28 km) from MD 26 in Libertytown east to MD 140 in Westminster. MD 31 connects the county seats of Frederick and Westminster via Libertytown in eastern Frederick County and New Windsor in western Carroll County. MD 31 originally extended from Frederick to Manchester, using the paths of what are now MD 26 and MD 27. MD 26 assumed MD 31 west of Libertytown in 1933 and MD 27 took over MD 31's route north of Westminster in 1967. The Westminster–Manchester portion of the state highway was constructed as one of the original state roads in the early 1910s. The remainder of the highway was built in the early to mid-1920s. MD 31 was relocated north of Westminster in the late 1950s and south of Westminster in the mid-1960s. The bypassed sections of the state highway became parts of MD 852.
Maryland Route 713 is a state highway in the U.S. state of Maryland. The highway runs 3.05 miles (4.91 km) from an entrance to Fort George G. Meade north to MD 176 in Hanover. In addition to serving as an access point to the U.S. Army installation, MD 713 provides the primary access to the Arundel Mills regional shopping mall and the Live! Casino & Hotel. MD 713 was constructed as part of MD 175 in the late 1920s and received its present designation in the mid-1940s. The northern end of the highway was relocated in the mid-1990s for the construction of MD 100 and modified again when Arundel Mills was built a few years later. One of MD 713's auxiliary routes connects the mall and casino with MD 295 via the first diverging diamond interchange in Maryland.
Maryland Route 194 (MD 194) is a state highway in the U.S. state of Maryland. The state highway runs 23.87 miles (38.42 km) from MD 26 in Ceresville north to the Pennsylvania state line near Taneytown, where the highway continues as Pennsylvania Route 194 (PA 194) toward Hanover. MD 194 is the main highway between Frederick and Hanover; the state highway connects the towns of Walkersville and Woodsboro in northeastern Frederick County with Keymar and Taneytown in northwestern Carroll County. MD 194 was blazed as a migration route in the 18th century and a pair of turnpikes in Frederick County in the 19th century, one of which was the last private toll road in Maryland. The state highway, which was originally designated MD 71, was built as a modern highway in Frederick County in the mid-1920s and constructed as Francis Scott Key Highway in Carroll County in the late 1920s and early 1930s. MD 194 received its modern route number in 1956 as part of a three-route number swap. The state highway's bypasses of Walkersville and Woodsboro opened in the early 1980s and mid-1990s, respectively.
Maryland Route 27 is a state highway in the U.S. state of Maryland. Known for most of its length as Ridge Road, the highway runs 39.17 miles (63.04 km) from MD 355 in Germantown north to MD 30 in Manchester. MD 27 follows a ridge that separates several watersheds in northern Montgomery County and Carroll County. The highway connects Germantown and Manchester with Damascus in far northern Montgomery County; Westminster, the county seat of Carroll County; and Mount Airy, which lies at the junction of Carroll, Frederick, Howard, and Montgomery counties and where MD 27 intersects Interstate 70 (I-70)/U.S. Route 40.

Around Cumberland, MD 51 is a major highway that provides a bypass of the South End neighborhood of that city and access to industrial areas along the North Branch Potomac River. South of North Branch, MD 51 is a rural highway connecting small communities along the river in southeastern Allegany County, including Oldtown. Documentation from the Maryland State Highway Administration depict the highway as following an east-west alignment, but all signage indicates a north-south road.

Known for most of its length as Green Valley Road, the state highway runs 28.40 miles (45.71 km) from MD 355 near Hyattstown north to MD 31 in New Windsor. MD 75 serves as the main north–south highway of eastern Frederick County, where it connects Hyattstown with New Market, Libertytown, Johnsville, and the Carroll County town of Union Bridge. The first sections of MD 75 were constructed around New Windsor and between Green Valley and New London in the early 1910s. The latter highway was extended south to Green Valley in the late 1910s. In the early 1920s, MD 75 was constructed between New Windsor and Union Bridge and from Libertytown to Johnsville. The remainder of the state highway was constructed in the late 1920s and early 1930s. MD 75 was relocated between Union Bridge and New Windsor in the early 1960s, around its interchange with Interstate 70 (I-70)/U.S. Route 40 in New Market in the early 1970s, and at its northern terminus in New Windsor in 2007.
Maryland Route 765 is a collection of state highways in the U.S. state of Maryland. These 26 highways are service roads constructed or old alignments maintained to provide access to private property or county highways whose access was compromised by the realignment of MD 2 and MD 4 in Calvert County. There are six signed mainline segments of MD 765 comprising the old alignment of the concurrency of MD 2 and MD 4 through Solomons, Lusby, St. Leonard, and Port Republic, and the county seat of Prince Frederick in southern Calvert County. There are also 20 unsigned sections of MD 765 south of Prince Frederick and along MD 2 between its junction with MD 4 in Sunderland and Owings in northern Calvert County.

MD 84 provides access to Uniontown and forms part of the connection between New Windsor and Taneytown in western Carroll County. The state highway was constructed from New Windsor to Uniontown in the mid-1920s. The northernmost portion of the highway was constructed in the late 1930s as MD 630, which became a disjoint part of MD 84 in 1951. The gap in MD 84 north of Uniontown was filled in 1956.

MD 806 is the old alignment of US 15 through Catoctin Furnace and Thurmont. The state highway was originally constructed in the 1910s. MD 806 was assigned to the highway when US 15 bypassed Thurmont in the late 1950s. The state highway became a split route in the late 1980s. There have been several other segments of MD 806 along former sections of US 15 in Frederick County, including portions around Lewistown and south of Frederick.
