The past and future of freeway landscapes

California’s freeways—its state highways, urban expressways, and interstates—cumulatively stretch 15,104 miles, end to end. Counting each lane separately, California has 51,326 drivable miles of freeway. Using the standard 12-foot width the state’s Department of Transportation, Caltrans, uses for roadbuilding, California’s freeway system covers roughly 116 square miles. If California’s entire freeway system were stretched out along its 840-mile coastline, it would be sixty-one lanes wide.

It’s about the way freeways look, the way they appear (or don’t) to the driver and passenger, how they use the land, and how their concrete forms have been sculpted and grafted onto the landscape.

Planned as ‘a landmark of beauty and pride for the entire city’, the Stack was the first of its kind, helping to create LA as a freeway metropolis and condemning its residents to largely car-dependent lives

The most famous – and most infamous – buildings in Los Angeles aren’t buildings. No one lives or works in them, but they have had an extraordinary impact on the city, its people, and the world as a whole. LA’s most important buildings are its freeways, and the most iconic piece of this vast network is the Four Level Interchange: an elegant vertical boating knot of freeways and ramps just outside downtown.
