The Gotthard Base Tunnel (in Switzerland) has opened. It is currently the world’s longest tunnel. The thought crossed my mind as to what contingency plans were put into place to evacuate people should something bad happen. According to Wikipedia, there are cross-access points every 1066 ft. for emergency stops and evacuation. Those areas also house air conditioning  apparatus, etc.

I think the tunnel was a great idea and will do much to alleviate traffic on overused, preexisting routes, but I don’t think it will be much of a draw for sight-seeing tourists. A rail ride through this tunnel would certainly be unique, but about as interesting a  theme park ride in a windowless submarine. 35.5 miles of boredom. Bring something to read.
