This document discusses the impacts of removing freeways and how it can positively impact cities. It notes that taking down freeways can reunite neighborhoods, provide waterfront access, encourage development, and create more attractive and walkable environments. However, it also cautions that simply removing freeways may not achieve the desired effects and other complementary changes would also need to be made, such as increasing mixed uses, safe streets, and active building designs. The document ultimately argues that removing barriers like harbors could help development and links between areas, which would further incentivize positive changes if a freeway was also removed.
