SAN DIEGO — A rockslide on Interstate 8 in rural East County is impacting traffic for drivers between San Diego and Imperial counties.

According to Caltrans, a large boulder and rubble was blocking traffic on I-8, near In-Ko-Pah Park Road Sunday.

One-way traffic control was put in place by Caltrans crews as they work to clear the rockslide from the freeway. As of noon Monday, these measures were still in effect.

“Caltrans crews on EB I-8 near In-Ko-Pah trying to remove the boulders that are about as big as a school bus,” Caltrans said in a post on X, formerly known as Twitter.

Officials said to expect delays in the area and to avoid unnecessary travel if possible.

Around 1 a.m. on Tuesday, Caltrans said in a post on X that the westbound lanes were back to normal in the area and that one eastbound lane had reopened.

According to Caltrans, crews worked through the night to reopen SR-78, SR-94 and other storm-related road closures as Tropical Storm Hilary swept through the region with powerful winds and heavy rain.
