The twin spans of the Blue Water Bridge cross the St. Clair River from Point Edward, Ontario, to Port Huron, Michigan. They are an unmistakable landmark, visible from across Sarnia, and the principal reason most travellers know the town's name. The pedestrian route along Centennial Park gives the best ground-level view of the bridges and the heavy lake traffic underneath.
For drivers, the crossing tends to move faster than the Windsor-Detroit bridges and tunnels to the south, especially mid-morning and late evening. Have your passport ready well before the booths — the queue is the only slow part.
