Last fall Sound Transit thought East Link construction would require three weekend closures in the 2nd Quarter of 2021 and two later in 2021 for testing.
In last month’s East Link Extension update (pdf), which has nice photographs of progress at each station, next quarter will now see five closures, two of which are for removal of the temporary platform at Pioneer Square. The two later closures will still be necessary.
The briefing didn’t name specific weekends. It’s unfortunate that the center platform is going away: while a center platform at Chinatown/International District Station would have been ideal for transfers between Link lines, Pioneer Square would at least provide an option for the mobility-challenged and those with a lot of luggage.
Alas, a permanent platform requires emergency egress and ADA accommodations. Still, if I were ST I’d just leave the platforms there and just not open the doors on that side in the hope that someday there could be a shovel-ready stimulus project to finish it.
In much better (and bigger) news, the project float is still intact, so pre-revenue testing should begin in early 2022, and if the float holds, service could begin later that year, well ahead of the formal target of September 2023.
