The Delaware Department of Transportation announced a new traffic pattern on state Route 1 southbound at Clapham Road and Buffalo Road, along with a new traffic signal to be activated Dec. 20 at the intersection of Buffalo and Clapham roads, Little Heaven.

State Route 1 southbound ramps A and B will be open to motorists.

These ramps will provide access to Buffalo Road and Clapham Road from state Route 1 southbound.

The next phase of this project will be the closure of Clapham Road, south of the Buffalo Road intersection. A date will be announced later regarding this road closure with detour information.
