The London Tower Bridge is one of the most beautiful bridges in the world. The model in the World Buildings Line was quite large and expensive, so I'm proposing a smaller model of the Tower Bridge, in the architecture line. It will still be as impressive, measuring 48 studs long and containing about 250 bricks. Something to be aware of: as this was designed on LDD, it was next to impossible to create the cables on the bridge, but if this is to become a set it should include them.
The bridge includes opening and closing drawbridges.
It also has the arch to allow vehicles to pass through.
If anyone knows how to build the cables in LDD, feel free to make a suggestion!
