Both directions of traffic are now open more than an hour after Interstate 40 lanes were shut after a tanker fire.
A truck fire has shut down part of Interstate 40.
Arkansas State Police said a commercial vehicle was reported on fire in the westbound lanes near Kerr, which is east of Little Rock, in Lonoke County.
