A load of nails were thrown across the M62 after a crash today.
The nails and other scrap metal were shed from a trailer as the vehicle towing it overturned between Junction 22 at Rishworth and Junction 21 at Milnrow.
It meant Highways Agency staff had to shut down two lanes of the busy motorway until the vehicle can be recovered and the motorway swept clean.
The driver of the Toyota Hilux which was towing the trailer was taken to hospital.
He is not thought to have serious injuries.
The crash happened between the two junctions shortly after 12 noon.
The Toyota Hilux was in collision with a Vauxhall vectra. The Toyota ended up on its roof and the trailer careered off the motorway into a ditch. The Vauxhall Vectra was also damaged.
Police and ambulance crews were called to the scene.
A Highways Agency spokesman sauid: “The vehicle was towing a trailer loaded with what was described to us as a portable car scrapping machine.
“The trailer has shed its load and we believe that included a lot of nails which have been spread across the carriageway.
“We have closed lanes one and two of the westbound carrigaeway and they will remain closed for some time.
“We are having to wait for a recovery vehicle to come and right the Toyota and we have also asked for a sweeping machine to come in to clear the affected stretch of the motorway.
“We hope we can have lane two open within an hour or two but lane one will stay closed for some time.”
