Map to the left shows the top limit of the Cwmbran stretch of the Monmouthshire and Brecon canal,( bridge 47 Solomans Bridge) just 230 yards above Bevans Lane.
Bridge 46 - Bevans Lane Bridge.
Bridge 45 - Cross Keys Bridge.
NB. Notice the Cwmbran tunnel between bridges 45 and 46 - a surprising number of people are not aware of it.
Also notice on the map - where Chapel Lane goes over the Afon Llewyd River - this is the top limit of The Cwmbran a.a. stretch on this river.
The letter L (as in L63 stands for lock number)
