In 1924, the Petitcodiac Tidal Power Company proposed a tidal power project. This called for a dam to be built between Hopewell Cape and Fort Folly Point. The company sold shares to raise funds for the project and a series of on-site and airborne studies were conducted by the federal government, but the project fell through by 1928. As rail transport became more common, it displaced river transportation around the Great Depression. In addition, the Greater Moncton International Airport offered an airmail service from Moncton to Montreal by 29 December 1929. These factors further marginalised the Petitcodiac.
