The interstate is the primary highway between Baltimore and Annapolis. I‑97 connects Annapolis with Baltimore/Washington International Airport and links the northern Anne Arundel County communities of Crownsville, Millersville, Severna Park, Glen Burnie, and Ferndale. It is the second shortest primary Interstate Highway after I-87 in North Carolina.
Maryland Route 201 is a state highway in the U.S. state of Maryland. Known for most of its length as Kenilworth Avenue, the highway runs 9.40 miles (15.13 km) also known as the road of Maryland from the District of Columbia boundary in Tuxedo, where the highway continues south as District of Columbia Route 295, north to MD 212 in Beltsville. MD 201 is a four to six-lane divided highway that connects Washington, D.C., with the northern Prince George's County municipalities of Cheverly, Bladensburg, Edmonston, Riverdale Park, College Park, Berwyn Heights, and Greenbelt. The highway also provides part of the connections from Interstate 95 (I-95)/I-495 to a pair of Washington Metro stations. MD 201 was built as two separate highways in the late 1920s: MD 201 from Washington, D.C., to Bladensburg and MD 205 from Bladensburg to Greenbelt. These highways, some of which became MD 769, were replaced with a relocated Kenilworth Avenue in the mid 1950s, including the Kenilworth Interchange with U.S. Route 50 and the Baltimore–Washington Parkway in Tuxedo. MD 201 was extended north to Beltsville in the early 1960s. The Maryland State Highway Administration (MDSHA) plans to extend MD 201 north toward Laurel.
Maryland Route 2 is the longest state highway in the U.S. state of Maryland. The 79.24-mile (127.52 km) route runs from Solomons Island in Calvert County north to an intersection with U.S. Route 1 /US 40 Truck in Baltimore. The route runs concurrent with MD 4 through much of Calvert County along a four-lane divided highway known as Solomons Island Road, passing through rural areas as well as the communities of Lusby, Port Republic, Prince Frederick, and Huntingtown. In Sunderland, MD 2 splits from MD 4 and continues north as two-lane undivided Solomons Island Road into Anne Arundel County, still passing through rural areas. Upon reaching Annapolis, the route runs concurrent with US 50/US 301 to the north of the city. Between Annapolis and Baltimore, MD 2 runs along the Governor Ritchie Highway, a multilane divided highway that heads through suburban areas, passing through Arnold, Severna Park, Pasadena, Glen Burnie, and Brooklyn Park. In Baltimore, the route heads north on city streets and passes through the downtown area of the city.

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. MD 103 replaced MD 176 from US 1 east to near MD 295.

MD 151 is a four- to six-lane divided highway that connects the communities of Edgemere and Dundalk on the Patapsco River Neck peninsula of southeastern Baltimore County with industrial areas in Sparrows Point and East Baltimore. MD 151 was originally constructed in the early 1920s from Sparrows Point to Edgemere. The highway was connected to Baltimore by the Baltimore County portion of MD 20, a number also assigned to the highway from Rock Hall to Chestertown in Kent County. During World War II, MD 151 was extended north through Dundalk on a new divided highway parallel to MD 20 and through East Baltimore on an expanded Erdman Avenue to connect the Bethlehem Steel complex at Sparrows Point with MD 150 and US 40. In the late 1960s and early 1970s, Interstate 695 (I-695) was constructed parallel to MD 151 between Edgemere and MD 157 in Dundalk.

MD 414 connects the inner suburbs of Oxon Hill, Marlow Heights, and Silver Hill and provides access to National Harbor. The highway was constructed through Oxon Hill and Marlow Heights in the early 1930s. MD 414 was extended through Silver Hill along the old alignment of MD 5 when that highway bypassed Silver Hill in the early 1950s. The highway was expanded to a divided highway between Marlow Heights and Silver Hill in the early 1970s, around its interchange with Interstate 95 (I-95) and I-495 in the early 1980s, and around MD 210 in Oxon Hill in the late 1980s.

Maryland Route 337 is a state highway in the U.S. state of Maryland. Known for most of its length as Allentown Road, the highway runs 3.41 miles (5.49 km) from MD 5 in Camp Springs east to MD 4 near Forestville. MD 337 runs along the southern end of Morningside and the northern edge of Andrews Air Force Base and provides access to several entrances to the military base. The state highway runs concurrently with the easternmost portion of Suitland Parkway. The parkway stretch of MD 337 is maintained by the National Park Service (NPS) instead of the Maryland State Highway Administration (MDSHA). MD 337 was constructed in the mid- to late 1910s along a course further south than the modern highway. The highway was moved to its present alignment to make way for the construction of Andrews Air Force Base during World War II. The easternmost part of the highway was constructed as Suitland Parkway. The Allentown Road portion of MD 337 was expanded to a multi-lane divided highway in the late 1970s and early 1980s. The Suitland Parkway segment was expanded to a divided highway in the mid-1990s. MDSHA plans to build an interchange at MD 337's eastern terminus with MD 4.

MD 260 was relocated to a road built on the railroad right-of-way from Lyons Creek through Owings in the mid-1950s.
Maryland Route 908 is a collection of unsigned state highways in the U.S. state of Maryland. These five highways are service roads that parallel and provide access to U.S. Route 50 and US 301 along their western approach to the Chesapeake Bay Bridge; the highways also provide access to Sandy Point State Park. The first modern highway from Cape St. Claire to Skidmore was constructed in the late 1920s and replaced by the modern alignment of US 50 in the late 1940s. The frontage roads on either side of the U.S. Highway were constructed in the early 1950s. The mainline segments of MD 908 assumed their present form when US 50 and US 301 were upgraded to a freeway in the early 1990s.
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.

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.

Northbound MD 4 followed the original alignment of MD 416 until MD 4 was upgraded to a freeway in the early 1990s and MD 794 was extended along its current course.
