The causeway, built in 1968, formed a wall blocking all but of water as the river flowed downstream toward the Gunningsville Bridge. Before the causeway's construction, the river's area would expand through Moncton, attaining a width of 1.6 km (one mile). A series of banks to both sides precede the 90-degree turn to the south, a feature that gave Moncton its original name, "Le Coude" (The Elbow). The river passes Dieppe on its eastern side and Hillsborough on its western side before it approaches its mouth.
