Police stated less than an hour later that all northbound traffic would be forced to exit at Dimond Boulevard.

Across town, police closed the westbound lanes of 15th Avenue at Gambell Street for another collision.

APD is advising all drivers to use caution.

KTVA meteorologist Carlos Faura said drivers can expect areas of patchy freezing fog, dense at times, in Anchorage Friday night and through Saturday morning.
