Last week Sound Transit released the Final Environmental Impact Statement (FEIS) for East Link. Press release here. After a group effort to look over the thing, there’s not a whole lot that’s particularly new, although over the next couple of weeks we might post on a few interesting details.
ST’s preferred alignment consists of alternatives A1, B2M, C9T or C11A, and D2A. The final decision on Segment C should come later this summer. The total cost is $2.3-2.7 billion (2007 dollars) for a surface alignment through downtown (C11A), or $2.6-3.1 billion for the tunnel option (C9T). C9T buys you an extra 1,000 daily riders (for a total of 50,000) in 2030.
The Executive Summary has one-pagers on each of the endless segment alternatives that ST considered.
