I'm not sure what the fascination with bridges and tunnels is, but the trips have been announcing every time we travel under a bridge. It started out as "going through a tunnel", but we have since corrected them and told them that we were just going under a bridge. So now each time we travel under a bridge, we hear a chorus of "goin under bridge!!" from the back seats. It's very cute, but can also get quite annoying on some stretches of road.
They've also carried this fascination over to play time. They have a little Thomas the Tank Engine set that has a bridge. Each time the trains go over the bridge or through the tunnel they announce it the same way they do in the car. Again, very cute, but it gets old really quick!!
