The San Juan Road area was a choke point for interregional travel along US 101 for goods movement, commuters and visitors. US 101 in this area had a high crash history and very high traffic volumes of over 63,000 a day. The project improved the area by removing three at-grade intersections (Dunbarton Road, San Juan Road and Cole Road) and constructing one interchange near the Red Barn. The new interchange has improved safety and reduced the congestion along this heavily traveled stretch of US 101.
The project started construction in December 2012 and was completed in July 2015. To follow highway updates or to see project photos, please join the TAMC Facebook.
