Authorities say a car crash has closed the main route between Phoenix and Las Vegas.
Arizona Department of Transportation officials say the northbound lanes of U.S. 93 northbound are closed south of Interstate 40 due to Thursday evening's accident.
Light rain has been falling most of the day in the Phoenix area, but it's unclear if the crash was weather related.
Details aren't immediately available.
ADOT officials say there is no estimated time to reopen the northbound lanes, but the U.S. 93 southbound lanes are unaffected.
They say drivers should postpone travel or consider an alternate route if possible.
