FULL OVERNIGHT CLOSURE OF HIGHWAY 9 NEAR
BOULDER CREEK SET TO TAKE PLACE WEDNESDAY, JULY 1
SANTA CRUZ COUNTY — Travelers on Highway 9 near Boulder Creek will encounter a full overnight closure on Wednesday, July 1.
This full closure will take place from 8 pm to 6 am at Kings Creek Bridge from Pool Dr. to Primavera/Old County Hwy as crews begin the process of setting new precast girders for the southbound portion of the new bridge.
A detour will be available via Highway 17. Message and directional signs will alert travelers in advance of the areas under traffic control. Please allow for extra time for your travels through the area. Community members in the area can expect noise overnight associated with this closure.
The current temporary signals will return to 24/7 signalized one-way control the morning of July 2. The one-way traffic control supports the Highway 9 San Lorenzo River and Kings Creek Bridge Replacement Project taking place north of Boulder Creek and involves the full replacement of these bridges for the safety of the traveling public. Crews are in the first phase of the project where they close the southbound lane to replace the southbound portion of the bridges below.
King’s Creek Bridge Replacement / Post Mile 15.41 to 15.55
San Lorenzo River Bridge Replacement / Post Mile 13.58 to 13.69
This is one of several full overnight closures to take place during these two bridge replacement projects. Updates will continue to be provided as these closures take place.
