UPDATE: The Globe got it wrong. What needs to be replaced is a 100-year old bridge near the new bridge.

Seems a bridge on the Greenbush Line could increase flooding in a big storm.

Speaking of commuter rail, that story also mentions that the T yesterday extended its contract with the MBCR for another three years. The consortium gets $50 million more a year. There are penalties for bad performance, but that's capped at a maximum $1.9 million a year.
