Earlier this year Transportation Secretary Anthony Foxx said he wants to help repair the damage done to cities by highways. And this week U.S. DOT took some steps to make that happen, announcing the winners of its “Every Place Counts Design Challenge.” The four chosen cities (out of 33 applicants) will get technical assistance from U.S. DOT to tear down or cap highways, or otherwise mend urban neighborhoods split apart by grade-separated roads. The winners are Spokane, Nashville, St. Paul, and Philadelphia. Jim Saksa at Network blog Plan Philly explains how Philadelphia plans to use the process to begin heal the divides created by the Vine Street Expressway.
