Nighttime milling and resurfacing of state roads is underway yet again. The state Department of Transportation began a project on a segment of Route 7 in Wilton, Redding and Ridgefield on Sunday.  Motorists can expect lane closures on Route 7 between Route 57 to just shy of Route 35.  The work is being done from 8pm to 5:30am.  Traffic control personnel and signing patterns will guide motorists through the work zone.  The project is scheduled to wrap up June 10th.
