A group campaigning for fathers' rights has ended its protest on the Clifton Suspension Bridge.
The protesters are campaigning for better access to their children
Three members of Fathers-4-Justice, dressed as comic book superheroes, scaled the bridge early on Monday morning and remained in place until just before 0900 GMT on Tuesday.
The bridge is now open to traffic and pedestrians.
The protesters have been arrested on suspicion of causing a public nuisance and will be taken to Weston-super-Mare police station.
On Monday night, protest spokesman Jeff Skinner said: "It's cold and it's wet but we are staying put and are not giving up. We will be here for the foreseeable future."
Mr Skinner said the men wanted to raise awareness of the "unfair" system of child access.
"All motorists have been denied access to the Suspension Bridge... as all our members are denied access to their children," he said.
Four protesters originally climbed the bridge, but one came down on Monday afternoon as he was feeling unwell.
