COLUMBIA, Mo. (AP) — Spilled nails led to backed up traffic on Interstate 70 in central Missouri.

KOMU-TV reports that traffic was snarled Monday morning on westbound I-70 after thousands of nails spilled along the highway in Columbia, creating a possible hazard.

Columbia police estimated that about 200 boxes of nails spilled, and each box contained about 2,000 nails. Police were still looking for the truck that spilled the nails.

Officials said the line of backed up traffic extended several miles, but the area was cleared and traffic was moving by mid-morning.
