Extinction Rebellion protestors have caused more traffic disruption with temporary blockades of the road outside the Ministry of Defence at Abbey Wood.
Activists used the same technique they displayed on the M32 on Tuesday, blocking the road completely for seven minutes at a time before letting the traffic flow freely for five.
Drivers faced heavy disruption, as the protests coincided with nearby road closures due to an ongoing hotel fire in Cribbs Causeway.
Action continued on Thursday afternoon with College Green in Bristol closed due to protests. A number of diversions are in place for public transport services around Anchor Road and Jacobs Wells Road.
The group positioned the blockade on the slip road from the ring road leading to the MoD, forcing traffic to redirect through Filton.
Congestion continued to build due to the A4018 Cribbs Causeway and surrounding roads being closed following the Premier Inn fire.
Travel West confirmed no trains were facing disruption, however First South West buses faced diversions and delays throughout the morning.
Local services were also affected by the disruption, with routes still facing knock on effects.
Southmead Hospital warned staff and visitors that journey times would need to be altered when travelling to the site.
