An informal gathering is being held tonight in Ridgefield about improving Main Street.  The state Department of Transportation plan is still under development.  Tonight's session is not a public hearing, rather a feedback session about improving traffic flow while keeping the look of Main Street similar to what it is now.  Initial plans call for turning lanes on Main Street, realigning the Prospect Street intersection, changing the timing of some traffic lights and possibly reducing parking spaces elsewhere.  The meeting at Ridgefield Town Hall is at 5:30pm.
