Work Continues Along Route 7

Construction activities will be ongoing along Route 7 through the spring and summer months. Surface paving will continue, and traffic shifts will occur in the Lewinsville Road area in preparation for the permanent configuration at the Route 7/Lewinsville Road intersection. Please see the project website for information on upcoming lane shifts and other roadway impacts.
