Baltimore's highway growth has done much to influence the development of the city and its suburbs.
The first limited-access highway serving Baltimore was the Baltimore–Washington Parkway, which opened in stages between 1950 and 1954.
Maintenance of it is split: the half closest to Baltimore is maintained by the state of Maryland, and the half closest to Washington by the National Park Service.
Trucks are only permitted to use the northern part of the parkway.
Trucks (tractor-trailers) continued to use U.S. Route 1 (US 1) until Interstate 95 (I-95) between Baltimore and Washington opened in 1971.

The Interstate highways serving Baltimore are I-70, I-83 (the Jones Falls Expressway), I-95, I-395, I-695 (the Baltimore Beltway), I-795 (the Northwest Expressway), I-895 (the Harbor Tunnel Thruway), and I-97.
The city's mainline Interstate highways—I-95, I-83, and I-70—do not directly connect to each other, and in the case of I-70 end at a park and ride lot just inside the city limits, because of freeway revolts in Baltimore.
These revolts were led primarily by Barbara Mikulski, a former United States senator for Maryland, which resulted in the abandonment of the original plan.
There are two tunnels traversing Baltimore Harbor within the city limits: the four-bore Fort McHenry Tunnel (opened in 1985 and serving I-95) and the two-bore Harbor Tunnel (opened in 1957 and serving I-895).
The Baltimore Beltway crosses south of Baltimore Harbor over the Francis Scott Key Bridge.

The first interstate highway built in Baltimore was I-83, called the Jones Falls Expressway (first portion built in the early 1960s).
Running from the downtown toward the northwest (NNW), it was built through a natural corridor, which meant that no residents or housing were directly affected.
A planned section from what is now its southern terminus to I-95 was abandoned.
Its route through parkland received criticism.

Planning for the Baltimore Beltway antedates the creation of the Interstate Highway System.
The first portion completed was a small strip connecting the two sections of I-83, the Baltimore-Harrisburg Expressway and the Jones Falls Expressway.

The only U.S. Highways in the city are US 1, which bypasses downtown, and US 40, which crosses downtown from east to west.
Both run along major surface streets; however, US 40 utilizes a small section of a freeway cancelled in the 1970s in the west side of the city originally intended for Interstate 170.
State routes in the city also travel along surface streets, with the exception of Maryland Route 295, which carries the Baltimore–Washington Parkway.

The Baltimore City Department of Transportation (BCDOT) is responsible for several functions of the road transportation system in Baltimore, including repairing roads, sidewalks, and alleys; road signs; street lights; and managing the flow of transportation systems.
In addition, the agency is in charge of vehicle towing and traffic cameras.
BCDOT maintains all streets within the city of Baltimore.
These include all streets that are marked as state and U.S. highways as well as the portions of I-83 and I-70 within the city limits.
The only highways within the city that are not maintained by BCDOT are I-95, I-395, I-695, and I-895; those four highways are maintained by the Maryland Transportation Authority.
