Homeland Security Department, Coast Guard
The Coast Guard is establishing a temporary regulated navigation area (RNA) on the Piscataqua River near the General Sullivan Bridge in Newington, NH, due to bridge demolition. The RNA imposes a "Slow-No Wake" speed restriction, limits vessel transiting through the bridge to a beam of less than 160 feet, and other restrictions. Full enforcement periods of the regulated area, prohibiting all vessel entry, will be implemented only during hazardous demolition operations involving multiple cranes lifts of structural steel over the navigational channel. This rule is necessary to protect personnel, vessels, and the marine environment from construction-related hazards.
