Switch heater installation will continue (and hopefully finish) this weekend, resulting in 30 minute headways from 10pm Friday through the close of business Sunday. Link will be operating single-track from between Columbia City and Stadium, so riders will be directed to one platform.
This resumes the work that began at the end of April. By taking a three-week break, Sound Transit avoided the entire Mariners and Sounders homestands, where weekend ridership is a bit higher.
The switch heaters are supposed to weatherproof the system in the event of another Snowpocalypse. We got a little lucky in that El Niño prevented any serious weather this winter.
