Certainly whoever was involved with the diversion signing around Reading when the M4 was closed at night between J10-11. I ended up heading back east towards London three times because the signs just seemed to disappear and my satnav (TomTom on my phone connected to my car via cable) just couldn’t show me a route to the M4 heading west on the other side of Reading.
I was getting ever more frustrated and angry, trying to find clear directions, because I’m not at all familiar with the roads around Reading, I think I’ve been there two or three times in my life, so I don’t know the area at all.
Eventually I found myself behind a van that seemed to be heading in the right direction, so stayed behind it, and several other vehicles joined the convoy, and ultimately I started to see diversion signs, and my satnav picked up the route. I didn’t get home until 3am, I lost around 45 minutes because of the farce that was the Highways signing.
