A part of Lake Zoar will be closed soon as work continues on the Rochambeau Bridge replacement in Newtown.  A request has been made to close the navigable channel from June 27th through July 8th, but reopened during the July 2nd through 4th weekend, as long as conditions are safe for the boating public.  The closure is needed due to work removing structural steel girders at span 2 of the bridge.  The construction company says this closure will ensure the safety of any nearby marine traffic during the operation. If the removal work is completed prior to July 8th, the channel will be reopened to marine traffic.  Additional closure signage will be installed prior to the closure, in accordance with the approved boat safety plan.
