Eight intersections along Frost Street in East Williamsburg are scheduled to have their pedestrian ramps torn out and rebuilt starting Monday, according to a weekly construction bulletin from the NYC Department of Design and Construction forwarded by Brooklyn Community Board 1 on July 19. The work runs July 20 through July 25, from 7 a.m. to 3:30 p.m., and dozens of additional corners across Bushwick, North Brooklyn, and Queens are on the week’s list.
