As of 5:42 PM, CHP reported that the center lanes had reopened, but the far right lanes remained blocked. Chopper footage showed multiple CHP units and Caltrans trucks stopped in the area with officers appearing to communicate with someone on the other side of the bridge railing.

All lanes had reopened by 6:20 p.m., but the traffic backup on westbound I-80 was bad enough that drivers would likely be seeing residual delays for some time.
