Clarkstown officials are holding a community meeting tonight to discuss the potential for added sound barriers along the New York State Thruway in West Nyack and Central Nyack. They say the State Thruway Authority needs to bring the noise levels under control, the result of an increased flow of commercial and commuter traffic. The Community Meeting is being held at 7pm tonight at the West Nyack Firehouse at 42 Strawtown Road in West Nyack.
