No Quick Fix for Montecito Bridges Damaged in Jan. 9 Debris Flows

Repairs to 6 spans estimated to take 8 to 12 months, due in part to need to relocate utilities

Numerous bridges over creeks in Montecito that were damaged or destroyed during the Jan. 9 debris flows likely will take eight months to a year to be repaired or rebuilt.

That means long-term detours for motorists traveling along Highway 192 in Montecito.

“This is the firmest construction schedule to date issued by Caltrans (the state agency responsible for Highway 192),” Matt Dobberteen of the Santa Barbara County Public Works' Transportation Division said this week during a community meeting in Montecito. “The goal is to have construction simultaneously with all of the structures.”

Crews need to conduct utility relocation for five badly damaged spans, which may hamper the construction process.

“Utility locations are the key drivers of the schedule,” Dobberteen said. “Utility relocations greatly complicate the nature of the construction. You have to move gas lines, power, and water. They won’t be taking out the bridges until utility relocation is complete.”

Demolition of the bridges and construction are the next steps.

“You should see the roadway being open up in the areas within eight to 12 months,” Dobberteen said.

The County Public Works Department and Caltrans are repairing six bridges hit with mud, boulders and debris during the storm, according to Dobberteen.

Four bridges will need to be replaced entirely, and two will need new guide railings because they were washed away, Dobberteen said.

The bridges needing total replacement are at Montecito Creek and Highway 192, just west of Hot Springs Road; the Romero Creek bridge, just East of Sheffield Drive; the Toro Canyon bridge at Toro Canyon Road and Highway 192 intersection; and Arroyo Parida Creek near Carpinteria, just west of Cravens Lane at Highway 192.

Through traffic over the bridges needing complete replacement is closed except for emergency and utility vehicles, Dobberteen said. 

Rail replacement is underway, Dobberteen said, for the bridge at San Ysidro Creek and Highway 192, near Randall Road.

“This is the only structure with no utility conflicts,” Dobberteen said.

The Toro Creek (near Ladera Lane) bridge rail replacement has begun, according to Dobberteen.

The two bridges have one-way traffic control, he said, adding that drivers “should be able to flow across the bridges with minor, temporary closures” throughout the reconstruction of the railings.

Crews are using precast bridge decks to expedite construction, Dobberteen said.

“Rather a more complicated process, or instead of pouring concrete at the site, they are bringing precast panels that should make the construction process go faster,” he said.

Drivers ignoring roadblock signs and barricades Friday evening near the Montecito Creek bridge at East Valley Road and Parra Grande Lane were heading straight into a disaster zone, making U-turns since the road remains closed to traffic and bridge repairs need to be done.

County emergency officials have asked residents to remain patient as crews embark the projects.

“It’s going to take some time,” Matt Pontes, assistant county executive officer, said this week. “We have three county bridges, and the rest is Caltrans.”

Noozhawk Asks: What’s Your Question?

Welcome to Noozhawk Asks, a new feature in which you ask the questions, you help decide what Noozhawk investigates, and you work with us to find the answers.

Here’s how it works: You share your questions with us in the nearby box. In some cases, we may work with you to find the answers. In others, we may ask you to vote on your top choices to help us narrow the scope. And we’ll be regularly asking you for your feedback on a specific issue or topic.

We also expect to work together with the reader who asked the winning questions to find the answer together. Noozhawk’s objective is to come at questions from a place of curiosity and openness, and we believe a transparent collaboration is the key to achieve it.

The results of our investigation will be published here in this Noozhawk Asks section. Once or twice a month, we plan to do a review of what was asked and answered.

Thanks for asking!
