Bristol City Council has revealed the five-day "occupation" of Bristol by Extinction Rebellion in July cost the authority £6,000.
Hundreds of protesters seeking to raise awareness of the 'climate emergency' occupied the bridge from Monday, July 15 until Friday, July 19.
A camp for the activists was also set up in Castle Park during the week, which was part of a country-wide rebellion called Summer Uprising.
The action was to encourage the Government to change its recently-set target for zero carbon emissions from 2050 to 2025.
During the week of action the protesters moved around the city to take part in different demonstrations - and on Wednesday, July 17, a group of campaigners blocked the M32 for several hours causing traffic chaos.
At the time the head of Avon and Somerset police revealed that the cost of policing the operation was likely to be "upwards of £300,000".
Police and Crime Commissioner Sue Mountstevens said it was "taxpayers' money" being spent.
She said officers' rest days had to be cancelled and some had to work 14-hour shifts, while still dealing with hundreds of 999 and 101 calls on a daily basis.
Now Bristol City Council has revealed the cost of the operation to the authority, which is much less than the police, at around £6,000.
A spokesperson for the council said the majority of the cost came from the installation of concrete blocks on either side of Bristol Bridge to stop traffic from trying to drive through the area.
Bristol Bridge acted as a base for the protesters during the five-days of disruption. It became home to a huge pink boat emblazoned with the words "tell the truth" where a number of speakers and artists performed during the week.
