Specifically, the Pioneer Bridge that crosses the Sacramento River. Back in 2014, CalTrans tried resurfacing the roadway over the bridge, and it was ok for a little while, but soon after completion the new road surface started lifting and chipping away. The reason is because the new surface didn’t adhere properly to the old surface. This left crevices in the road, uneven and uncomfortable to drive over.
Well, they’re about to fix everything, but they’re doing a much more in-depth repair. They’ll be grinding away what’s left of the new, failed surface, and even going further into the old surface. We’ll save the details for their own website about the project (also will have scheduled closings on the page), but starting tonight around 10:00, they’re planning to close down some lanes for the whole weekend, set to reopen Monday morning around 5:00. Random on and off-ramp closures throughout the weekend too.
It sounds like there will be a couple lanes open, but there’s a ton of traffic through that area so expect to see delays all weekend, and plan to take other ways to your destination, like the I-5/80 interchange in Natomas, and they say even the Tower Bridge could be another way around, but that will likely be delayed due to the detours.
