Highway 400 was closed in both directions between Highway 88 and Highway 9 after a transport truck lost its load Thursday afternoon.
The tractor trailer collided with another vehicle near Canal Road around 1:30. Then a highly flammable liquid which was believed to be paint thinner began to leak from the trailer.
The area was evacuated while the cleanup took place.
Later in the evening a fatal collision closed the south bound 400 near at Rutherford.
