Sure, but you have to start somewhere. Why waste money digging up the same street over and over, as most cities do? It seems more efficient to do it once and be done for a long time thereafter.

Here in Seattle, we spend $$$$ buying a tunnel boring machine, bore a transportation tunnel for a section, and then ...

It's like setting up a giant printing press to print a newspaper, and then printing 10 copies.
