Interstate-94 near Kalamazoo, Michigan is open to all traffic, two days after 200 cars and trucks were involved in a deadly pile-up.
The pile-up happened Friday morning during white-out conditions.
One truck driver from Canada was killed in the crash.
A semi-trailer carrying 40,000 pounds of fireworks crashed and exploded.
Another semi, transporting acid, created a challenging clean-up for crews that worked around the clock in sub-zero temperatures.
Crews were able to remove the last of the vehicles early Sunday morning and the pavement was checked for problems.
All lanes were re-opened to traffic by 4:30 a.m. Sunday.
