[the urban politician]

I have a question:

If we are basically building some boarding islands, painting (maybe?) some lanes, and (I hope) introducing signal priority, why does this project cost millions and millions of dollars?

Heck, I'm rehabbing a building right now and the concrete floor slab is only a couple thousand bucks.

So many millions?

I'm really not trying to be a smart ass, but I guess I just don't understand the infrastructure involved with this project to justify the price. If anybody could explain I would appreciate it.
