Ever since the M4 motorway crossing the River Severn was built in 1966, there has been a bridge toll. Although this didn’t stop us going to Wales for the day, or longer periods, we were less inclined to pop over for a short visit when it would cost us an extra £6 or so. Now, though, the toll has been abolished, opening up new possibilities for, for instance, brief dog-walking sorties. Here we are, more-or-less opposite Portishead. The newer bridge, the “second Severn crossing”, is in the distance.
