57 th Street Crossing Consider Flasher Consider Rectangular Rapid Flashing Beacon Pedestrian Recommendations Sidewalks (54 th Street – Westfield Boulevard) Provide 6-foot sidewalk (west side) Widen existing sidewalk (east side) Separate sidewalk from curb (both sides) Sidewalks (Crossing Streets) Provide 6-foot sidewalks where feasible Give priority to 56 th Street (safe routes to school)
