PERRYSBURG, Ohio (AP) — Authorities in Ohio say a load of nails spilled on a roadway during rush hour, leaving about a dozen commuters with flat tires.

State troopers say one lane of traffic on Interstate 475 just south of Toledo was closed for over an hour Wednesday morning to clean up the spill.

Troopers estimate that there were about 200 nails scattered across the roadway.

The spill happened at around 7 a.m. between Perrysburg and Maumee (maw-MEE’). No one was hurt.
