Tunnel

There are two ways to get to Rodeo Lagoon in Marin County: the Marin Headlands road and the half-mile long Baker-Barry Tunnel. This is a one-way tunnel, that is, one way at a time. For five minutes traffic goes in one direction and for the next five minutes, it goes in the other direction. Truly - five minutes - there is a red light at each end of the tunnel and traffic takes turns. Drivers turn off their engines while waiting their turn. There are bike lanes on each side of the one lane and the bicyclist can punch a button before entering to activate a flashing light so that motorists will know there is a bicycle in the tunnel.
