So you’re paid up. Nice. Now you have to actually drive through the thing. The southbound bore is the scary one – it’s single-lane, narrow, and damp. It looks like a villain’s lair.
And the height limit? 4.0 metres (13 feet 1 inch). If you’re in a tall van, check your roof. The tunnel loves to say “hello” to your roof rack. It won’t be a friendly hello.
Also, no bicycles. No pedestrians. No horses. Just cars, vans, and your newly paid-for anxiety. You’ll come out the other side blinking like a mole, but you’ll be legal.
