The Galipeault Bridge has reopened in both directions.
The bridge linking the western tip of the island to Île-Perrot along Highway 20 has been closed since Saturday due to elevated waters levels.
Transport Quebec said it doesn’t expect water levels to rise this weekend as was initially feared.
Tolls were eliminated on Highway 30 during the closure, and will remain free until midnight Thursday.
Train service was offered free on weekdays during the closure to avoid congestion.
