Indeed! But looking at the EDP site - I'm from Norwich, so nostalgia? - I saw this and wondered if it might have any bearing on my upcoming slog northward as a potentially typical example of current British road situations.
On an aside note, the main concern I have is how to avoid missing a strategic turn on my route and ending up on a motorway, so wondering about the conditions shown in the photo, I posted my plaintive worry, here.
For example: one line on my cue sheet is:
'A sort distance along the road bends to the left with 'Cedars House' in front of you and Wells Cathedral School. Turn R at the bend in the road down the one-way-street at the "School sign".
What happens if the "School sign" as disappeared, or Cedars House' is now a migrant centre called Alibaba?
For example: On the day I travel the 114 miles from Street to Bewdley - over the Bristol Channel - there are 100 cue changes of direction. Very easy to miss one - or more cues and finish up on the 'Safe Lane' of a motorway.
Rather than be dismissive, as some other posts have been, I'll try to help.
The first point is to emphasise it would be incredibly difficult to join a motorway but not impossible. I wouldn't worry about this. Saying that only yesterday as I joined the M65 (a local motorway) near Preston a car came towards going the wrong way on the motorway! Scary!
As for general navigation your cue sheet suggests you've used mapping software of some form. Can you put this on a GPS unit? It will be the simplest solution.
I once rode from home to Bordeaux without using a GPS unit. I carried maps. Each evening I would study the next day's route, noted the road numbers and village names and approximate distance between each village in a small note book (about 2" x 2"). I carried the notebook in my jersey pocket and simply referred to it when needed.
It sounds to me as though your cue sheets offer every minute detail, possibly the routing is diverting on to very quiet or traffic free lanes. I would advise against carrying reams of paper. If you do get lost, miss a turn it will quickly become apparent and quick reference to a map will correct you.
Going back to cycle lanes. In the UK we have a huge range of cycle paths varying from very good to utterly disastrous. My buddies and I do use them if it suits us. We would ignore the example you posted.
The good ones will be fairly obvious. Broadly speaking the decent ones will be signed on the lines of these below. The signage is generally good but can be difficult to spot. I rode the Pennine Cycleway, 350 miles, using only the signage. I had maps as backup but hardly used them, if at all.
