Los Angeles' vast freeway system is incomplete — at least by the standards of its architects. In the 1940s, freeways were sketched through Santa Monica Boulevard, along Melrose, Highland and La Brea avenues, and near the Griffith Observatory. Many of L.A.'s freeways were built during the 1960s, but a combination of a freeway revolt, skyrocketing costs and a failure to increase the gas tax doomed the expansion of the freeway system during the 1970s. — LA Times

It’s been named one of the top “Freeways Without Futures” in the nation and described as a “perfect example of obsolete infrastructure.” [...]

Now, nearly half a decade later, the project to remove a large portion of the Terminal Island (TI) Freeway in West Long Beach has officially gone out to bid in an RFP with an estimated bid value of $225K. It marks a major event in Southern California’s urban design history, being the first freeway removal project [...]. — longbeachize.com

The story of Boyle Heights reminds us that urban highway teardowns don't always end in victory. [...]

"What we don't know, however, is the story of the losers, the urban men and women who fought the freeway, unsuccessfully, on the conventional terms of political struggle, who weren't able to pack up and move on, and who channeled expressive cultural traditions to register their grievances against the presence of unwanted infrastructure." — citylab.com

While searching for images of highway interchanges in urban areas, I came across these historic aerial photos of Detroit on a message board, showing how the city fabric has slowly eroded. It’s a remarkable record of a process that has scarred many other American cities. — usa.streetsblog.org

You can’t build your way out of congestion. It’s the roads themselves that cause traffic. The concept is called induced demand, which is economist-speak for when increasing the supply of something (like roads) makes people want that thing even more. [...]

What [economists] Turner and Duranton (and many others who’d like to see more rational transportation policy) actually advocate is known as congestion pricing. This means raising the price of driving on a road when demand is high. — wired.com

So it is that nearly a third of the interstate system consists of stretches through our cities, in the form of loops, spurs and freeways. So it is that American motorists drive nearly twice as many miles on urban interstates as they do the lengthier rural legs. So it is that every metropolis in the country has reorganized itself around these roads, and that they've shaped where we live and work, how we shop, what we eat, and how we pass our time. — theatlanticcities.com
