Two semi-trucks carrying hay caught fire on northbound Interstate 5 Friday afternoon.
Around 3 p.m., reports came in of a semi-truck hauling hay having caught on fire. The first truck was traveling north about four miles north of Williams at the time.
Thick black smoke started billowing out from the burning hay, causing visibility issues for all lanes of traffic. The smoke was reportedly able to be seen from five miles away.
Around 15 minutes later, a second semi-truck caught fire. It is unclear as to what caused the second hay-bearing truck to catch fire, though wind appears to be the suspected reason.
Immediately both lanes of northbound I-5 were shut down due to the size of the fire and potential spread due to wind, as well as the possible explosion from the fire reaching the gas tank. Minutes later, officials announced the closure of southbound I-5 as well.
The fires have caused massive traffic delays in the area, and all drivers are being detoured to use Highway 20 all the way to 99 instead.
FOX40 will have more on this story as it develops.
