Woodbury is looking to install floodgates at roads in the area that usually flood.  This comes on the heels of the line of duty death of State Police Sergeant Brian Mohl, who was swept away by the waters of the Pomperaug River earlier this month.  Woodbury’s Emergency Management Director says one area they're looking at is Jack’s Bridge Road and Jusdson Avenue.  Posts for the gates would be installed behind guardrails so drivers couldn't go around them.  Woodbury officials have asked the state Department of Transportation to pay for the infrastructure for Washington Road, which is Route 47, and Sycamore Avenue, which is Route 317.  The town also plans to apply to FEMA for a grant.
