A proud team in front of the SR 520 pontoon casting basin in Tacoma
WSDOT engineers Mike Cross, Chris Stearn and Ernie Marinig take a moment to pose in front of the SR 520 pontoon casting basin in Tacoma, celebrating the start of another successful float-out operation.
Beginning July 27, 2013, crews floated eight supplemental stability pontoons out of the casting basin in which they were constructed, at the Concrete Technology Corporation site in Tacoma, WA. These pontoons are the third of six of cycles of pontoons to be completed at this site.
After each cycle, pontoons are inspected and temporarily moored prior to being towed to Lake Washington and used in assembly of the new SR 520 floating bridge.
