Motorists are in for a long wait as the M1 is closed in both directions between junctions 25 and 26.
Notts Police said officers were called at 11.30am this morning (Friday, December 16) due to a police incident.
The road will be closed for some time.
A photograph of a man taking his dog for a walk among the stationary traffic was posted on Twitter by @simply_sport.
He posted: “Now that really isn’t a good sign. A bloke walking his dog on the M1, yes M1. I think I might miss kick off.”
