The Lake Zoar Authority Marine Patrol is alerting boaters that the channel on Zoar will be closed Monday through Friday.  This is part of the ongoing Rochambeau Bridge reconstruction project.  The navigable channel between some of the bridge’s pillars will temporarily be closed to marine traffic.  During the closure, structural steel is being erected over the channel.  If the steel is in place prior to Friday, the channel will be reopened earlier.  The two bridges that carry Interstate 84 over the Housatonic River are being fully rehabilitated. Currently, the eastern bridge is open, the western bridge is being renovated.
