It's time to head towards the Severn Bridge.
We ended up on the Northern side of the bridge despite very obvious signs and the fact the correct path was painted red! The Southern side seemed to be better connected and offered better views, so we backtracked a bit to go under the motorway onto the other side.
The bridge looked as if it were very steep, but in fact we only stopped a couple of times to take pictures, but otherwise it wasn't hard at all to ride up the bridge.
Just as the diversion ended, we made a bit of a mistake — we wanted to see the Severn estuary, so we took the path which seemed to go closer to it, but in fact it just went along a very busy road.
At some point we returned to the 41 but soon I made a navigational mistake and we ended up on the Port Way cycleway, which was very far from being pleasant, as it followed a very busy dual carriageway along the river Avon, while the 41 went across the river under the trees.
Anyway, we made it into Bristol, albeit much later than we originally planned.
