Urban Island or: How I Learned to Stop Worrying and Love Flatbush Ave.


A new transportation hub is created by submerging Flatbush Ave. and cutting the terrain to reveal the upper level of the subway below. Prospect Park expands into the spaces left above.


  • Flatbush Ave. submerged
  • transportation hub connects bus/subway routes; subway tracks are exposed
  • Arch becomes formal Park entrance
  • pedestrian bridge spans Flatbush, includes an annex reading room to the adjacent Library
  • greenmarket moves to a new space in west/center Plaza
