MARINE PARK - Residents in Marine Park say they are concerned about a dangerous intersection in need of a stop sign or speed bump. Neighbors say they have put petitions together to improve traffic safety at Stuart Avenue and Avenue S, but still struggle to cross the street. They say a stop sign was put up a quarter-mile south of the spot, but that has not deterred motorists from speeding. In addition, a public park and school sit near the intersection. "It's just a disaster waiting to happen," longtime resident John Westbay says. Department of Transportation officials say they will re-examine the intersection to see if changes are appropriate. Westbay says officials already looked at it two years ago, finding nothing was wrong.
