In Downtown Atlanta, the Downtown Connector or 75/85 is the concurrent section of Interstate 75 and Interstate 85 through the core of the city. Beginning at the I-85/Langford Parkway interchange, the Downtown Connector runs generally due north, meeting the west–east I-20 in the middle. Just north of this is the Grady Curve around Grady Memorial Hospital. Continuing north, the terminus of the Downtown Connector is the Brookwood Interchange or Brookwood Split in the Brookwood area of the city. The overall length of the Downtown Connector is approximately 7.5 miles (12 km). Since the 2000s, it has been officially named James Wendell George Parkway for most of its length, although it is still designated the Connector in the mainstream. It also has unsigned designations State Route 401 (I-75) and State Route 403 (I-85) along its length, due to I-75 and I-85 having 400-series reference numbers.

Transportation in Seattle is largely focused on the automobile like many other cities in western North America; however, the city is just old enough for its layout to reflect the age when railways and trolleys predominated. These older modes of transportation were made for a relatively well-defined downtown area and strong neighborhoods at the end of several former streetcar lines, now mostly bus lines.

State Route 480 was a state highway in San Francisco, California, United States, consisting of the elevated double-decker Embarcadero Freeway, the partly elevated Doyle Drive approach to the Golden Gate Bridge and the proposed and unbuilt section in between. The unbuilt section from Doyle Drive to Van Ness Avenue was to have been called the Golden Gate Freeway and the Embarcadero Freeway as originally planned would have extended from Van Ness along the north side of Bay Street and then along the Embarcadero to the San Francisco-Oakland Bay Bridge.

Signed as U.S. Route 99W, it had been the major route through the city and its removal is often cited as the first instance of freeway removal in the U.S. and as a milestone in urban planning; the original road is remembered as the first limited-access highway built in the city.

Freeway removal is a public policy of urban planning to demolish freeways and create mixed-use urban areas, parks, residential, commercial, or other land uses. Such highway removal is often part of a policy to promote smart growth, transit-oriented development, walkable and bicycle-friendly cities. In some cases freeways are re-imagined as boulevards, rebuilt as below-grade freeways underneath caps-and-stitches, or relocated through less densely-developed areas.
