During the bridge demolition activities, a forty-foot work barge will be located within the navigational channel of the bridge and will not be able to relocate from the reduced navigational channel of the existing and new bridge structures. Vessels should not transit through the existing and new bridge structures and should adjust their transits accordingly. R.E. Pierson Construction Company tug and vessels will monitor VHF-FM channels 13 and 16 when work is in progress or vessels are operating in the area.
