A truck loaded with car tyres caught fire in a tunnel in Prachin Buri late on Thursday night, and the north-bound road was still closed to traffic on Friday.
The blaze began in the tunnel between Khao Yai and Thap Lan national parks in Na Di district of Prachin Buri about 11.35pm and was initially thought to have been put out, but the fire started again on Friday morning.
The truck was destroyed.
Fire trucks and crews sent to the scene saw thick smoke coming from the tunnel. The front section of the truck was on fire. Firefighters took more than one hour to bring it under control.
According to the driver, the fire started without warning while it was inside the tunnel. He tried to continue to the end of the tunnel, but had to abandon the burning vehicle.
After the flames were extinguished, the truck was later towed out of the tunnel for investigation and left near the entrance.
Around 10.30am on Friday, the fire suddenly erupted again, this time in the cargo container. Firemen were again battling the flames.
