Radical Rethink: Couple Mobility and Housing

To solve this Gordian Knot, mobility and housing could be and should be coupled. Many of America’s largest cities have major interchanges usually with adjacent unused patches of land. Using the city of Los Angeles as an example, some of its major interchanges include the 405/10, 101/110, and 405/101 freeways.

Building a 20+ story predominantly residential tower at interchanges, dedicated to affordable housing (prioritizing essential public servants—health, education, and policing) with some mixed use, might help to alleviate the paucity of housing.

Complementing these new vertical spaces in key nodes around the city would be a transport system that rapidly moves the adjacent population to another node.
