Main Street in Ridgefield is closed at the intersection with Governor Street for a state Department of Transportation road reconstruction project.  Prep work was done last night, with the full closure as of midnight.  The closure will continue through Sunday.  First Selectman Rudy Marconi says all stores in the area will remain open with their normal business hours, though there will be a restricted amount of parking.  Drivers are asked to be patient during the work.  The Main Street Project has been designed to reduce traffic congestion and enhance pedestrian safety. It's fully funded by the Federal and State governments.  Marconi notes that none of the work is related to any other commercial or residential developments.
