Black Lives Matter protesters have closed part of the M6 motorway after up to 100 people started walking in the road.
It has been reported that protesters began marching in the middle of the M6 southbound carriageway at around 5pm on Sunday.
Witnesses have described seeing a police helicopter and dog handlers attending the scene of the protest near junction three of the motorway near Coventry.
One road user said protesters used cones to bock off the road before police arrived the scene and a "rolling roadblock" stretching back as far as junction two was put in place.
Motorists said they had been left queueing for more than an hour as police managed traffic.
Speaking to Birmingham Live, an eyewitness said: "I was going 70mph then they just walked out into the road in front of me.
"They put traffic cones down and then sat down. I’d say there are 100 here. They came on at junction three of the M6 and now there’s a rolling roadblock to junction two.
"The traffic has been held both sides. The police helicopter is up and there is a police dogs team here as well. The group were chanting ‘Black Lives Matter’ over and over again."
Police in the area tweeted to urge motorists to avoid the area. They said: "We are receiving reports of pedestrian protesters at junction three of the M6 in the southbound carriageway.
"Southbound is now currently closed.
"Please seek alternative routes and be wary if you are traveling on the M6."
