The first 6 of 33 pontoons under construction in Aberdeen were floated out into Grays Harbor tonight. These include some of the first world-record-breaking-360-foot-long longitudinal pontoons that will form the backbone of the new floating bridge. Here’s a photo sequence, courtesy of WSDOT/OxBlue construction cams:
The first of 44 supplemental (“water wing”) pontoons were floated out of Tacoma last week.
UPDATE Monday 10pm: New information from the Aberdeen casting site via Seattle Times reporter Mike Lindblom’s Twitter feed:
