The Dartford tunnel has been partly closed after activists staged protests at multiple locations on the M25 around London.
Essex Police said someone climbed a gantry over the road at junction 31 on the northbound carriageway at Thurrock at about 07:00 GMT.
It said it was working to remove the protester and its team was at the scene.
Both northbound tunnels were closed earlier, but one has since reopened.

Earlier, police said the protest would cause “major disruption” to motorists using the M25 to cross from Kent into Essex.

“Due to the dangerous position in which the protester has placed themselves it is likely to be necessary to close the remaining two lanes of the London-bound track of the M25”, it said.
Just Stop Oil activists said about 15 of its supporters were on gantries at “multiple locations”.

Hertfordshire Police said it had responded to reports of “protest activity” at junction 20 (Kings Langley), junctions 21a (Bricket Wood) and junction 22 (London Colney) of the M25.
It had closed some lanes for officers to assess the situation, it added.
It asked drivers to avoid the area and find alternative routes.
Surrey Police said its officers were dealing with protesters who have climbed on to motorway gantries between junctions eight and nine (Reigate), and junctions 12 and13 (Staines).
“Traffic is currently stopped in both directions at these junctions,” the force said.
