Full Description

Show more
The California Department of Transportation (Caltrans) proposes to improve the safety of SR 116 at the intersection of Green Valley Road in Sonoma County. SR 116 is a two-lane conventional highway, and the intersection is controlled by stop signs only on Green Valley Road in both directions of travel. This project discusses two build alternatives: a signalized intersection (traffic signals system) and a roundabout. The signalized intersection proposes to realign and widen the SR 116 and Green Valley Road intersection. The roundabout proposes to construct a 180-foot-diameter roundabout shifted about 35 feet southwest of the existing intersection. Both build alternatives would improve safety for the traveling public by reducing the potential and severity of collisions at the intersection.
