Any other airports in the world that you can walk to directly?

When I visited Pisa, Italy, I was amazed that I could walk right out of the airport right on to the road where my hostel was, ~12 minutes away by walking. I'd never experienced this before!

Are there are other airports in the world where this is also possible? I'm talking about a road with a sidewalk to the airport, as theoretically any airport could be "walked to" if you walked on a highway.

Edit: Maybe I should have specified, being able to walk there directly from the city center.
