Part of Route 7 in Ridgefield will be closed this weekend for a bridge replacement project. The state Department of Transportation is replacing the bridge just north of Route 102. This is the second of five scheduled weekend closures that will take place over the next several months. The next closure will take place in July. Local traffic and those needing access to businesses on Route 7 between 35 and 102 will still be allowed access except to the area where the bridge construction is taking place.
