Told you it was the busiest weekend of the year...... hope it clears soon!
It took nearly 7 hours to get down to south Devon on Friday
3.5 hrs from Carbis Bay to just outside Exeter , where had a stop off at a relative & 3.5 hrs from there home. The first but was abt an hour longer and I suspect had I followed the satnav, I’d have saved that time. As usual, the traffic just disappeared past the “hold up”.
A30 in or out of Cornwall on a weekend over the summer months is always solid. Much better plan is to go there and back on a midweek day.
