On December 23, we took an important step toward replacing the vulnerable State Route 520 floating bridge. We announced the contractor team with the apparent best value for building the new SR 520 floating bridge concrete pontoons in Grays Harbor County.
Kiewit-General Joint Venture submitted a $367.3 million bid, which is $180 million less than the state engineer’s estimate for the project. The team had the best combination of bid price and technical score, which reflected proposed plans for a pontoon construction facility, how quickly the new pontoons could be built, and environmental protections.
By combining design and construction in one contract at a fixed price, taxpayers are assured that costs are controlled and the contractor team has more opportunities for innovations.
Building these pontoons prepares us to respond to a catastrophic failure of the SR 520 floating bridge should it fail in a windstorm or earthquake. Web site.
To all of you following the SR 520 Pontoon Construction Project, we appreciate your interest. We’ll be back in the New Year with more news and progress. Happy Holidays!

The pontoon project is estimated to support more than 2,000 direct and indirect jobs. We look forward to breaking ground in Grays Harbor County late next year, and a new SR 520 bridge is scheduled to open in 2014. For more details about our projects, check out our
