We get a weekend of Link back

As the first stage of the project to connect the East Link track to the existing line, Sound Transit planned three weekend closures to build a temporary center platform at Pioneer Square. ST needs it to continue operations during a 10-week project to actually build the track switch, from January to March 2020.

The second of these weekend closures finished the platform, so that ST could cancel the third closure yesterday. The closure would have been November 9-10.

Each closure involved a bus bridge serving stations from Sodo to Capitol Hill. Usually a feature of unplanned service disruptions, the bridge will return for three complete closures next year. They were supposed to run in pairs every 7 minutes.

I had bus alternatives (and, in one pinch, a car) and didn't miss Link much on a quiet weekend. How did others think ST and Metro did with the bridge? How was signage, frequency, crowding, and reliability?
