Last week, the Washington D.C.-based urban planning nonprofit Smart Growth America held a three-day virtual summit about improving racial equity and taking action on restorative justice in housing, business development and transportation. Day three, dedicated to the latter, centered around the environmental, health, and economic damage inflicted by the interstate highway system, envisioned in the 1950s and ’60s as massive urban renewal projects which, in actuality, razed homes and businesses, displaced residents, carved up neighborhoods, introduced massive amounts of concentrated auto emissions into neighboring predominantly Black and Latino communities, and created a high-speed conduit for white flight to the suburbs.
