Indigenous activists briefly blocked a Mercier Bridge access ramp in a show of solidarity with opponents of a pipeline project in North Dakota, Kahnawake Peacekeepers said Friday night.
The activists erected a blockade on Highway 132 around 5 p.m., preventing motorists from taking one of the South Shore on-ramps.
The protest ended around 7 p.m., Peacekeepers said.
The protest was in solidarity with the Standing Rock Sioux, who have been holding a series of protests in recent months against the Dakota Access pipeline in southern North Dakota.
Riot police broke up a protest camp there on Thursday, drawing condemnation from Indigenous groups across the U.S. and Canada.
