Baker-Barry Tunnel for kids
The One-Lane Tunnel. The true story of the Baker-Barry Tunnel, near Sausalito, CA, told for kids.

Read along
Uh oh, see that traffic light? This tunnel is so skinny that only one direction of cars can go through at a time! So we take turns, and sometimes we have to wait up to five whole minutes for the green light. The army dug this tunnel through the hill about one hundred years ago, so soldiers could travel between Fort Baker and Fort Barry on the other side.
Here's a game for the wait. Let's count to one hundred, super slowly, and see if the light turns green before we finish. Ready? One...
two... three...
