Now that we all know April 29th is the date the tunneling machine is set to start going under the Alaskan Way Viaduct – closing it precautionarily for “about two weeks” – that date will be top-of-mind for a while. Something else that’s big for the city also starts two weeks from today: This year’s cruise-ship season. The first ship on the schedule, Holland America’s Nieuw Amsterdam, will be here that day. But it’s docking at Magnolia’s Pier 91, not the Viaduct-side Pier 66. According to a Port of Seattle fact sheet, this year’s season will bring the most passengers ever – just under 960,000. The 203 ship dockings aren’t a record, though; that number peaked in 2010, with 223. Last ship on the Seattle schedule this year will be the Star Princess, on October 21st.
