The westbound lanes of Interstate 70 at the Kansas River Bridge were shut down Thursday morning after a pallet of nails fell off a truck bed and spilled onto the highway.
Kansas Turnpike Authority spokeswoman Lisa Callahan said the accident happened at 6:05 a.m. just east of mile post 202.
Callahan said at least four cars received flat tires before crews could close the highway to clear the scene.
I-70 re-opened just before 9 a.m.
No one was injured.
