Yes! It looks like London is getting a little more European, making a huge roundabout at the Hale and Trafalgar intersection. This will be London's biggest construction year ever! You can check out this PDF of all the projects this year, even if it's almost over. It's pretty exciting!
I know theoretically how to drive into one, but to actually try it out ... we will see :)
It might just be a disaster like the Griswolds in European Vacation "Look Kids! Big Ben, Parliament!". Click here to see the clip, as I couldn't embed it! It's a classic :)
