Question 11:

Southwark Bridge may not be the most famous crossing over the Thames, but it has a glowing legacy - literally. When the original bridge opened in 1819, it was lit at midnight by 30 gas lamps, a striking innovation at the time. Today, the bridge is illuminated by dozens of modern lamps, continuing its tradition of lighting the way across the river.​
