Biggest tunnel boring machine ever and we end up with a tunnel that has the same number of traffic lanes as the old. Progress!
It does have improvements such as a small provision for emergency vehicles to squeeze by or pulling a disabled vehicle out of the way, and hopefully it is resilient to quakes. Still... Lot of expense for the same 4 lanes.
