Thomas Heatherwick's proposal for a Garden Bridge across the Thames has reached another milestone with the signing of a construction contract for the project. If you haven't been following the project, Heatherwick has proposed a new green bridge in central London. The amount of trees and soil proposed on this bridge are quite substantial and will require a feat of engineering to support the weight. To explain the scale of what they are trying to do, they have generated an infographic.
There are a lot of different aspects to the project. Other news outlets (like CNN) are making a big deal about the project's inspiration derived from the movie Titanic. But there is also a concern about how much green space will be lost to make this artificial green space.
