Ever been stuck at a raised bridge that won't come back down? Stressed about being late because a cargo ship is passing through?
OpenBridge predicts lift bridge openings on the Saint-Lawrence Seaway up to 3 hours in advance, combining official SLSMC announcements, real-time AIS vessel positions, and a continuous learning model calibrated on thousands of observed lifts.
ACTUAL ACCURACY (empirical measurements over 14 days)
Over 95% of Seaway lifts are announced in the app before they happen.
