Description

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 vessels transiting through the bridge to a beam of less than 160 feet, and other restrictions. Full enforcement periods prohibiting all vessel entry will be implemented only during hazardous demolition operations involving multiple crane lifts of structural steel over the navigational channel. This rule is necessary to protect personnel, vessels, and the marine environment from construction-related hazards.
