The state Department of Transportation is doing a paving project in Ridgefield.  The work along a 1.87 mile stretch of Route 102 is slated to last throughout this week.  The milling and paving will be done between Route 35 on Main Street and Bloomer Road. Construction will be done between 7am and 4pm.  Traffic control personnel will be at the work zone helping guide cars through the area, but drivers are urged to remain alert and proceed cautiously.  Residents should expect delays due to alternating traffic and plan accordingly.  The state delegation, at the request of First Selectman Rudy Marconi, called on the DOT to pave the entire length or road as the roughest part is outside of the project area.
