Update: One lane of the eastbound 10 Freeway was open as of 9:30 a.m. Thursday, according to Caltrans.

Eastbound lanes of the 10 Freeway in Riverside County were washed away Wednesday evening when heavy rainfall delivered a flash flood.

The flooding occurred just before 8 p.m., impacting the 10 Fwy south of Joshua Tree National Park, Caltrans said.

Initially, both directions of the freeway were closed. Westbound lanes, which were not impacted, reopened a short time later.

Photos and video captured by @devincroft showed water flowing through a wide, deep gash in the eastbound lanes, along with sections of drainage pipe that were overwhelmed and scattered by the floodwaters.

Caltrans recommends the following detours:

“If commuters are looking to get to Blythe or AZ, use SR86/111 to I-8 from the 10 or I-15 to I-40 into Needles. Crews working on cleanup efforts for other routes,” Caltrans tweeted Thursday morning.
