Yikes. Looking at the pictures, I see a structural failure. It's not something that's likely to be fixable; likely it's a full replacement. That means they'll have to demolish the bridge, reassess the geography, design a new bridge (with all the safety and environmental considerations that entails under law), and then build it.

Having a break in Highway 1 is going to be a big hit to the tourism based economy of the Central Coast for some time to come. Not to mention the daily living of local residents.
