Low Bridge Alert System
Safety-first mobile app for truck drivers in the UK
Project Overview
We developed a mobile app for a UK-based logistics company to help prevent bridge strikes, a major risk for high-clearance vehicles. The goal was to provide silent, always-on protection to drivers without distracting them from the road.
The app tracks live location and alerts drivers of approaching low bridges with increasing urgency. It also integrates with the company’s fleet software to automatically track height of the currently used vehicle. The app is used daily by over 100 drivers across the UK and provides centralized reporting for admin teams.
Key Features
- Live GPS tracking with alert zones around every UK bridge
- Two-tier alerts: standard at 500m, critical at 100m with sound
- Extensive, up-to-date database of 14,000 low bridges across the UK
- Integrates with fleet software to sync vehicle height automatically
- Admin panel with alert logs and access control
- Fully functional offline, syncs data when reconnected

The Challenge
Bridge collisions are costly, dangerous, and often preventable. The client needed a tool that would work in low-signal areas, adapt to each truck's height, and keep the driver focused on the road while being protected at all times.
- Live GPS tracking without draining battery
- Reliable offline functionality and bridge data updates
- Seamless integration with 3rd-party fleet software
- Deliver alerts without disrupting driver's attention
Our Solution
We created a purpose-built mobile app with background tracking and adaptive notifications. Built with rural coverage in mind, it uses offline bridge data, syncing only when connectivity is available.
- Silent background operation with precise GPS polling
- Custom notification engine with proximity triggers
- Monthly offline bridge data refresh with audit sync
- Secure login with email-based driver access
- Admin dashboard and webhook connection for reporting
