Putting commuter trains on the Interstate 90 bridge will require protecting the structure against damage from stray electrical current and may require innovative ways to attach the rails to avoid damaging the span, a panel of experts told state lawmakers Wednesday.
A Sound Transit project manager said the trains would likely have to slow for a few seconds while crossing joints between the floating bridge and its approaches. And who would pay for what part of the project is still being worked out.
“This is very new to us, the idea of putting light rail on a floating bridge,” said state project manager Theresa Greco.
I think the idea of transit in general is new to our state’s Department of
Highways Transportation. These guys see that center span as theirs, and they look at any project that doesn’t rely on cars or buses as suspect.
During the meeting, Rep. Judy Clibborn compared installing light rail on I-90 with The Big Dig. Really? Putting rails on a floating bridge is the same as the most ambitious public works project in American history? Making “Big Dig” comparisons is a sort of “Godwin’s Law” of transportation arguments: every project you oppose is the same as the “Big Dig.”
How can something be a “Big Dig” when we’re not even digging?
