WSDOT had a drawing to select a few members of the public to get a tour of the 520 bridge. I entered and won! I was so happy that they opened the bridge while we were out there, I had always wanted to see how it worked. It was just as cool that we got to go down inside one of the pontoons. Those things are crazy, like a mix of the hatch from lost with an old level from Quake or something. Seriously, if you design video games you must check this place out.
