ION Phase 2 - Cambridge's Light Rail Transit

[Bob_McBob]

I find it hard to believe regional staff and an independent private consulting firm are part of a conspiracy to inflate the cost of Stage 2. I would like to see significantly more details about how they arrived at the estimate as well as what comparable projects it's based on though. It's worth pointing out the actual estimate is $2.7 billion, or $3.25 billion with contingency, and would have been considerably less if the project was already under construction. There's an extra $1.2 billion added on entirely due to cost escalation while the region spends a decade planning and attempting to secure funding.
