The state highway was paved in Warwick by 1910 and constructed from Warwick to Cecilton in the late 1910s. West of Cecilton, what is today MD 282 consists of part of former MD 283, which ran from Crystal Beach to Earleville. MD 282 was constructed to Earleville in the early 1920s and extended a short distance west of Earleville in the late 1920s. MD 283 was constructed in the late 1920s and early 1930s. MD 282 was extended west to Crystal Beach along MD 283 in 1959. The highway from Cecilton to Crystal Beach was reconstructed in the late 1960s.

MD 343 was paved in the late 1920s and early 1930s. The state highway originally passed through downtown Cambridge, ending just west of its present terminus. After the original Choptank River Bridge was completed in the mid-1930s, MD 343 was truncated to Sunburst Highway. In the mid-1950s, the state highway was rerouted along Washington Street to Race Street, where it ended at MD 16. Finally, MD 343 was extended to its present terminus when MD 16 bypassed Cambridge in the late 1960s.
Maryland Route 235 (MD 235) is a state highway in the U.S. state of Maryland. Known as Three Notch Road, the state highway runs 30.63 miles (49.29 km) between its southern intersection with MD 5 in Ridge and its northern intersection with MD 5 near Mechanicsville. While the southern part of the state highway is a two-lane undivided rural road, the northern part of MD 235 is a four- to six-lane divided highway connecting Naval Air Station Patuxent River and the Washington, D.C., metro area in conjunction with MD 5. Three Notch Road has been the main highway between northern St. Mary's County and Point Lookout since the colonial era. The highway was reconstructed as the modern MD 235 between 1923 and 1938. The state highway was then completely rebuilt during World War II to serve the recently established NAS Patuxent River. Between 1960 and 1985, MD 235 was converted into a four-lane divided highway to the west and north of the military base. In the face of increasing activity at the base, the highway adjacent to NAS Patuxent River was expanded to six lanes in the early 2000s.
Maryland Route 38 is a state highway in the U.S. state of Maryland. Known as Kitzmiller Road, the state highway runs 5.67 miles (9.12 km) from the West Virginia state line at the North Branch Potomac River in Kitzmiller, where the highway continues south as West Virginia Route 42, north to MD 135 on top of Backbone Mountain. MD 38 connects Kitzmiller with the rest of Garrett County and across the North Branch Potomac River to Blaine and Elk Garden in western Mineral County. The state highway was constructed in the late 1920s and early 1930s. MD 38 originally ran from U.S. Route 219 near Thayerville through Deer Park and Altamont to Kitzmiller.

MD 260 connects the twin towns of Chesapeake Beach and North Beach in northern Calvert County with highways to Upper Marlboro, Washington, Annapolis, and Baltimore. Much of the highway follows part of the course of the former Chesapeake Beach Railway, which ended service in the mid-1930s. MD 260 was constructed in the early 1920s from MD 2 south of Owings east to Chesapeake Beach. The highway was extended west to what is now MD 4 south of Dunkirk in the early 1930s. MD 260 was relocated to a road built on the railroad right-of-way from Lyons Creek through Owings in the mid-1950s.

The highway is indirectly named for George Washington, who traveled the highway in 1783 on his way to Annapolis to resign his commission in the Continental Army at the conclusion of the American Revolutionary War. MD 178 was planned as early as 1910 as part of a western route between Baltimore and Annapolis. However, most of the highway south of MD 3 was not built until the early 1930s. The portion south of MD 3 served as a primary segment in the western corridor connecting Baltimore–Annapolis, until the construction of Interstate 97 (I-97) in the late 1980s.
Maryland Route 408 is a state highway in the U.S. state of Maryland. Known as Mount Zion-Marlboro Road, the highway runs 5.62 miles (9.04 km) from MD 4 at Waysons Corner east to MD 2 and MD 422 in Lothian. MD 408 is the old alignment of MD 4 in southern Anne Arundel County. The highway was constructed in the late 1910s and became the easternmost part of MD 4 in 1927. The highway received its present designation in the mid-1960s when MD 4 was rerouted south into Calvert County. MD 408's western end was relocated when MD 4 was upgraded to a freeway through Waysons Corner in the early 1990s. MD 408 was also applied to the old sections of MD 4 between Andrews Air Force Base and Upper Marlboro in Prince George's County. The number was assigned after the MD 4 freeway was completed in the mid-1960s. The Prince George's County portions of MD 408 were transferred to county maintenance in the late 1970s except the section through Upper Marlboro, which became MD 725.

The highway was built in the late 1910s and early 1920s and originally passed through Mount Rainier. The portion of MD 208 between US 1 Alt. and US 1 was originally MD 206; the northern portion of the highway was originally part of MD 209 and then MD 410. MD 208 was extended to MD 500 and removed from Mount Rainier in the late 1950s, and extended south through Cottage City around 1970.

These four highways are old segments of MD 67 between Rohrersville and Boonsboro in southeastern Washington County. These highways were designated when MD 67 was relocated in the early 1960s. The longest segment is MD 858F, which runs exactly 1 mile (1.6 km) between a pair of intersections with MD 67 in Rohrersville. In addition to the four existing highways, there are several county-maintained segments of old MD 67 between Rohrersville and Boonsboro and at Gapland, Brownsville, and Weverton south of Rohrersville.

The unsigned highway runs 1.86 miles (2.99 km) from MD 28 east and south to Carrolton Road in the Norbeck area of eastern Montgomery County. MD 655 is an L-shaped route with east–west and north–south segments that parallel MD 28 and MD 97, respectively. The highway and its auxiliary routes form parts of service roads along MD 28 and MD 97. The route follows what were two of the original state roads constructed in the early 1910s. MD 655 was assigned to the north–south segment when MD 97 was relocated in the late 1960s. The highway was extended west when MD 28 was relocated in the early 1980s.
