The incident was initially reported as a police chase after a recreational vehicle was seen driving erratically on the interstate, Caltrans spokeswoman Terri Kasinga said.
The vehicle was stopped after the CHP deployed a spike strip in the area, located about halfway between Indio and Blythe, just after 10:30 a.m. The agency issued a SigAlert, according to an incident log.
The CHP would not give details on why the freeway was closed for so long, but another CHP dispatcher previously said the shutdown was the result of a pursuit termination.
