Watford Gap, in the UK. Note the motorway (the M1) and railway (the West Coast Main Line) sharing the transit corridor, adn how much more space-efficient the railway is. That train is probably carrying more people than all the cars, and it does it faster!

Everyone always uses infrastructure, but no one truly appreciates it. In fact, most people don't even know the names of the freeways or railways that are right next to them!

That's way I created Quiz-frastructure, a combination of quiz and infrastructure, to help teach people about all types of infrastructure, from roads and railways to culverts and dams.

Take a look around, and appreciate the infrastructure that surrounds us!
