A line of police blocked protesters from marching down a motorway as part of a Kill the Bill demonstration in Bristol.
Some demonstrators sat down on the M32, chanting “we are peaceful” along with “whose streets? Our streets.”
However, the protesters returned to the city centre around 10 minutes later after debating whether to keep the blockade in place, Bristol Live reports.
The Bristol march is one of dozens of demonstrations being held across the UK this weekend in opposition to the Government's Police, Crime, Sentencing and Courts Bill.
At just before 10pm, Avon and Somerset Police tweeted: "The group (around 100 protesters) have marched onto the M32 and are currently sat on the carriageway.
"The motorway has subsequently been closed to inbound traffic at Junction 3 in the interests of safety."
At 10.45pm, the force added: "The M32 at Junction 3 is now open in both directions. Protestors briefly obstructed both carriageways before turning around and marching back into the city centre."
Protests on March 23 and 26 in Bristol ended in clashes between the police and protesters.
Avon and Somerset Superintendent Mark Runacres said the force respected the democratic right to protest, however he urged people to find other ways to share their views during the pandemic.
The area commander for Bristol said: "We fully respect the fundamental democratic right of being able to protest and we have a long and proud history spanning many years of facilitating peaceful demonstrations.
"While we’re expecting significant numbers to attend, we’d still urge people to consider finding alternative ways to express their views given that we’re still in the midst of the pandemic.
"Restrictions may have eased but large numbers of people congregating together at any one time continues to present a risk of spreading Covid-19."
