The purpose of this app is to give drivers an indication of traffic conditions on and around the bridge. There are six web cams available, two on the Runcorn side, two on the Widnes side and two in Ditton.
Both the approaches to the bridge and the bridge itself are covered by the web cams.
(Please note that in the UK, it is illegal to use mobile phones whilst driving. This app is intended to be used only whilst it is legal to do so.)
