|Route outline (key)|
Starts at Tower Hill, London EC4, on the A3211, then runs across Tower Bridge to meet the A2/A201 at the Bricklayers Arms junction. It's a primary route, part of the inner ring road, and consequently part of the Central London Congestion Charging Zone boundary. As such it is one of only three fixed link crossings between the Congestion Charging Zone and the eastern boundary of London - and that's assuming the bridge isn't open. The others are the A101 (Rotherhithe Tunnel) and the A102 (Blackwall Tunnel).
At the north end the change from A3211 to A100 apparently happens at the point where the former A100 (Great Tower Street, now unclassified) bears off. This puts a small section of the A3211 in the 1-zone.
Tower Bridge opened in 1894. Ever since then, it has been possible to buy a souvenir of Tower Bridge, making it one of the few roads you can buy in model form.
In 2003, it became a border of the London Congestion Charge zone.
