Road curve signs along several streets in Connecticut are being reviewed by the state Department of Transportation. One of the projects that will be systematically reviewed is along Route 53 in Redding.  The signs along the scenic road will be looked at to see if any need to be upgraded, or if more need to be installed.  The purpose is to reduce the number of fatal and serious injury crashes at curves with consistent treatment based on national best practices.  But the DOT says signs on curves that are no longer warranted will be removed.  All of the work will be performed in the state's right of way.  The project is not slated to begin until the Spring.
