Eastbound traffic was jammed Friday night as emergency crews responded to a vehicle fire on the H-1.
Officials say a tractor trailer ignited on the shoulder of the freeway around 8:30 p.m. HFD says the male driver wasn't aware the trailer was on fire until passing motorists alerted him.
All but one eastbound lane near the Gulick Overpass was closed as crews battled the flames causing a Black Friday traffic nightmare for some.
"I passed by on the Gulick overpass and saw the container enveloped in flames and HFD's engine company trying to extinguish the fire. There was no explosion but the fire was getting big, but HFD had it under control," witness Wayne Shinbara said.
HFD officials say the truck was being used to transport canned food and dried food items.
Fire crews extinguished the flames almost an hour later, around 9:20 p.m.
It's unclear what caused the trailer to ignite, but the fire started near the rear axel, officials said.
Emergency crews remained on scene well past 10 p.m. Roads were reopened around 11 p.m.
