March 2016 will be a big month for Capitol Hill transit. If everything goes to plan — and it has, mostly, through four years of work so far — Broadway’s Capitol Hill Station and the 3.1 mile University Link extension of Sound Transit’s light rail network will begin “revenue service” a year from now.
In the agency’s “2015 Service Implementation Plan” (PDF), Sound Transit planners lay out the timeline for the $1.8 billion project to begin carrying passengers next March as part of its regular schedule of service changes through its various bus and rail services.
Trial runs on the line are expected to begin “in Fourth Quarter 2015,” according to the document produced last December. “Testing for the University extension is expected to begin either at or sometime during the September 2015 service change,” the document notes elsewhere in the plan.
UPDATE: We’ll let you parse this response from a Sound Transit spokesperson:
We really don’t know that U Link will open in March, 2016. All we know right now is that it will be in the first quarter – could be anytime Jan-March at this point. The service changes that the SIP referred to are any changes that happen as/after U Link opens, not the usual service changes that happen in February.
The spokesperson tells us that Sound Transit is planning to update the document “to say U Link opens in Q1 next year.” The original wording? “Testing for this alignment will begin in Fourth Quarter 2015 with revenue service anticipated to begin with the March 2016 service change.”
