Climate change activists Insulate Britain have blockaded the M25 for the eighth time in three weeks.
Protesters targeted junction 30 near Thurrock in Essex at around 8am in the morning and glued their hands to the tarmac.
Essex Police said they had arrested nine people on suspicion of obstruction of highway.
An earlier post on their Twitter account added: “We are currently on scene of disruption on the M25 at J30 for Thurrock.
"We were called to reports of people blocking the road and officers responded within minutes.
"We are currently working to resolve the situation as quickly and safely as possible."
The force added: "We know this will be frustrating for people using the road but we appreciate your patience and understanding."

The incident marks the eighth day of action by the group on Britain’s busiest motorway in the last three weeks.
Insulate Britain, which is calling on the Government to insulate all UK homes by 2030 to cut carbon emissions, said in a statement: "We are raising the tempo this week as, despite the urgency of the situation, there has been no meaningful response from the Government to our demands."
On Wednesday members of the group blocked the same section of the M25 twice in a day.
They descended on Swanley Interchange, at around 7.30am in the morning, before returning at 1pm.
Drivers were seen arguing with the activists as they blocked the roundabout, with one motorist appearing to attempt to drag a protester out of the way.
Kent Police said 16 people were arrested during the second demonstration on the M25 on Wednesday, after 11 were detained earlier.
A force spokesperson said: "Officers arrived on the scene within three minutes of the report and arrested 16 people on suspicion of obstructing the highway and conspiracy to commit criminal damage.

Ministers are set to seek a new blanket injunction against protesters to halt their continued court-defying blockades of the M25.
Government sources said they would be asking the judge to do away with having to serve injunctions on the protesters individually.
The move would expand the injunction already in place but which the protesters have defied to continue their protests on the M25.
