SR 246/Alamo Pintado Road traffic operational improvement project is located on SR 246 between US 101 and SR 154 in Santa Barbara County within the City of Solvang.  The existing intersection experiences recurrent congestion during peak traffic flows.  Vehicle queuing develops during the A.M. and P.M. peak hour commute, at mid-day, and in the early afternoon periods when the Santa Ynez High School is let out.

It is proposed to improve traffic operations of the existing intersection by widening the roadway, using a roundabout or signals as a traffic control treatment at the intersection, and widening the Alamo Pintado Road Bridge.  Three build alternatives ranging in cost from $6,410,000 to $10,770,000 and a no build alternative have been considered.
