Rumble strips are being installed on Route 7 in Brookfield beginning later this week.  The Connecticut Department of Transportation says the project consists of milling the existing pavement surface to add a shoulder rumble strip on Friday and Saturday, between 7pm and 5am.  Motorists can expect lane closures on Route 7 from Silvermine Road to Federal Road. Truck mounted lights, Traffic control personnel and signing patterns will be used to guide motorists through the work zone.  Drivers are asked to remain alert, drive cautiously, and maintain a safe speed when moving around the work zone.  Modifications or extensions to this schedule may become necessary due to weather delays or other unforeseen conditions.
