Two new stop signs have been installed at a Ridgefield intersection creating a three way stop.  Ridgefield Police are alerting motorists to this intersection change at North Street and Copps Hill Road.  The stop signs were added for both north and southbound traffic on North Street.  Police say the change was made at the recommendation of the local traffic authority to improve roadway and traffic safety.  Earlier this month, a stop sign was added for southbound traffic on Grove Street at Sunset Lane making that intersection a three-way stop.
