Reviewing the project is not a great solution for reducing cost either. Delaying construction will result in higher costs in the long run especially if the economy picks up again.
Being that the proposed line is so long that they could start at opposite ends - simultaneously - and work towards the downtown and meet in the middle and that would take less time overall to get it built

Construction on public transit rail lines usually happens at multiple locations in parallel, limited generally by the construction bandwidth and sometimes logistics around transportation line disruptions. They are not building a 46km tunnel, so this concept of starting 46 km apart and joining in the middle isn't as realistic as you may think. The current phased approach, with hope of new funding opportunities, will indeed target continuous build-out all the way, but will allow a strong usable portion that can be operating before continuing to phase 2/3.

Yep. They're building a new 40+km subway line right past where I live in Shanghai, and it's very easy to follow the line's route just by looking at where the construction sites are located. Pretty much every station location has related above-ground construction, though the amount of surface construction really depends on the density of the surrounding area - areas with high density have less surface construction.
