About this app

Which Bridge is designed to allow people living in the South West of the UK to keep up to date with closures on the M48 and M4 bridges (Severn Bridges), otherwise known as the Severn Crossing.

The primary benefit of this app is that it'll send push notifications to your mobile device (and watch) when there's a closure or re-opening on one of the bridges. No more forgetting to check before you leave! This app offers you a view of planned closures over the next 7 days, all on one beautiful screen! In addition, we've added a feature that will send you a notification when traffic is building on the bridges and we'll send you a notification to keep you up to date about expected delays on your journey over the M4 or M48 Severn Bridges in South Wales/England. We even tell you how long to expect your journey over the bridges to take! The app now also uses AI to monitor current wind conditions to predict when a closure might happen!

But that's not all...Introducing "Commute Briefs"! The know before you go pro option that allows you to schedule daily notification briefs to give you the real time status of one or both bridges before you head out the door for work or back home from the office. Pick a time, pick the days, it's up to you!

But it doesn't even stop there! "Cheapest Fuel Finder" helps the app pay for itself by showing you where to save at the pump, anywhere in the UK.. That's smart!

Which Bridge? is a must have for anyone who makes regular journeys to England/Wales over the Severn Bridges.

It happened this morning, on the app was showing the bridge (M48) is closed, and I had to rush to work and by my surprise it was opened. So asking money for something that is not really accurate or giving real time information is not a great option. Fix that please.

Thanks for your feedback, and my apologies. Over the past few days there have been unusual events where traffic has been stopped due to incidents on the bridge rather than normal “bridge closed” events and this has broken my code. Happy to say I’ve already put measures in place to deal with these types of events in the future. Many Thanks, Josh

update - seems ok now. Very useful, I have staff who travel from Bristol to Chepstow so planning and checking are vital. V4.1: just installed but can't get past the welcome 3 screens. The done button doesn't work, skip button neither. keen to update this review to 5 stars when it's fixed! V4 1.1 skip and done buttons are still v low and clash with native triangle circle square at base of screen?
