This does seem crazy, but I don’t know what else a metropolitan area can do.

ALISO VIEJO, Calif. – Traffic is so bad along the eastern rim of Los Angeles’ suburban ring that regional planners are considering the once unthinkable — an 11-mile tunnel through a mountain range in earthquake country.

I guess they could stop building houses, but that’s seems rather unlikely. I’d hate to drive into that 11-mile tunnel.
