Seoul has removed the Cheonggye freeway and restored the river that it covered in order to stimulate the economic revival of central Seoul's Dongdaemun district. It has built busways to replace the freeway capacity, and it the goal of this plan is to reduce automobile use from 27.5 percent to 12 percent of all trips.
The trend in urban highways around the world is to removing or reducing them. Not expanding them as the MTQ proposes!
San Francisco, USA
The Embarcadero Freeway in San Francisco was so severely damaged in the 1989 Loma Prieta earthquake its closure was required. To the surprise of some, this event did not result in gridlock. Instead, traffic adjusted to the
new conditions and the decision was made to tear down the damaged infrastructure. It was replaced by an urban boulevard that has become a tourist destination, rather than an eyesore.
