So, yes, you can drive through the Blackwall Tunnel for the grand sum of zero pounds. But don’t celebrate too loudly—that free entry comes with a side of existential dread and the very real risk of your sat-nav screaming, “Recalculating!” as you emerge in a completely wrong part of South London. It’s the only tunnel where you pay with your nerves.
To sum it up: No charge. No cost. Just a free, damp, slow-moving ticket to the other side of the river. And if anyone ever tells you they paid a fee for the Blackwall Tunnel, they’re either lying, deeply confused, or they paid a man in a van to push them through during a traffic jam. Save your money for a coffee afterwards—you’ll need it after that trip.
