The new 5 metre timber bridge at Bishton is over an ancient drainage ditch known as a 'Reen' synonymous with the Gwent Levels which is essentially the corridor of flat-ish wetland adjacent to the Severn Estuary that spans three counties. It is steeped in history and much of it has been designated as a SSSI.

Part of the Llanwern Hill circular walk, this Bison Bridge has been installed as part of a project to promote and protect this area of land.
