If I were to phase it, I would do:
- Blue Line NE to Redstone
- Green Line S to South Hospital
- Green Line N
I think Green Line North probably is the best of those projects, however the first two are really low risk / high return in the immediate sense to really boost Green Line and Blue Line numbers.
But my list is thinking too small. Better yet, pick all three simultaneously and line up the project schedules to share resources, phasing, expertise and efficiency in delivery. Incrementally build out all of them at the same time so by 2030 we are done all of them and on to brand new projects.
