The protestors are blocking access to the second-largest petrochemical complex in the world.
700,000 barrels of the Oil pass under the bridge on an average day.
According to activists, the purpose of the blockage is to bring attention to climate change.

Earlier this year, the U.S. briefly became the largest oil exporter in the world before Saudi Arabia took that title back.
