Chip sealing continues on Route 302 in Bethel and Newtown.  The state Department of Transportation project involves replacing catch basin tops as needed, crack sealing, patching repairs to the existing pavement, the application of Asphalt Rubber Chip Seal over the existing pavement surface, and new pavement markings.  Construction work takes place Monday through Friday 9am to 3pm and 6pm to 6am, and weekends 6pm to 10am.  Alternating one-way traffic is to be expected through each work zone. Comer Contracting is slated to wrap up work on Route 302, Route 188 in Southbury, Seymour and Oxford, and Route 179 in Barkhamsted and Hartland by mid-October.  The total project cost is $3.5 million.
