Petitcodiac causeway

This is the story of the remarkable campaign that brought about the restoration of the Petitcodiac River, situated on the Bay of Fundy in the province of New Brunswick. In 1999, the battle to restore free flow to the Petitcodiac by opening the gates of the controversial causeway was entering its fourth decade. The local community was still bitterly divided and elected officials, just as content to leave matters alone, mostly avoided getting involved or tended to side with the more affluent lobby of residents living along the 21 km long artificial headpond, created in 1968 when the Petitcodiac causeway was built. By 2000, massive silt deposits covered 95 percent of the river near the City of Moncton and extended 35 kilometres downstream to Shepody Bay.


Between 1999 and 2010, Riverkeeper set out to reverse the situation by implementing a series of ground-breaking actions in environmental communications and environmental law enforcement. Ultimately, these efforts prevailed, leading to the opening of the gates of the Petitcodiac causeway in April 2010, the end of Canada’s longest environmental battle and the commencement of North America’s largest river restoration project.
