Bridge Status

NEW: Bridge lift info is now available on Waze and Google Maps.

Please click on the links to access bridge status applications:

• St. Catharines / Thorold
• Port Colborne
• Salaberry / Beauharnois / Suroît Region
• Montreal South Shore
• Kahnawake

We encourage St.Catharines / Thorold bridge users to “TAKE THE GREEN” as bridges highlighted in green should remain available for the next 15 minutes. When bridges need to close for longer periods of time (i.e. for maintenance purposes) a message to this effect will be visible.
