The 14 Freeway northbound in the Acton area remains closed after a big rig over-turned, spilling airline fuel all over the freeway earlier this morning. According to current CHP estimates, this problem is not expected to be resolved for several hours. Consider using Sierra Highway as an alternate route for the time being if you need to get up to the Antelope Valley. KHTS will update you with new information, both on the air and on our website, as soon as we receive it.
