## What is OpenBridge?

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.

### 5/5 — WoW merci!

*2026-07-29*

Tellement heureuse d’avoir cette application qui me simplifie vraiment la vie au quotidien!

### 5/5 — Application efficace!!

*2026-07-29*

Enfin une application efficace! J'habite dans le coin depuis de nombreuses années et cette application est la seule à prévoir d'avance la levée du pont. Je ne m'en passerais plus!

### 5/5 — Très bien fait

*2026-07-29*

Milles merci d’avoir réalisé cette belle application tellement plus facile maintenant!

### 1/5 — Site

*2026-07-23*

Le site de la ville de Valleyfeild offre la même chose a 0$

**Developer response:** Bonjour, merci pour votre retour.

Petite précision : le site de la Ville indique l'état actuel du pont. OpenBridge anticipe les levées longtemps d'avance en suivant les navires en approche, et vous avertit avant même de partir via une alerte, un widget sur l'écran d'accueil ou directement dans CarPlay.

C'est la différence entre constater et éviter. Si vous voulez qu'on vous aide à configurer tout ça, écrivez-nous, on est là.
