Challenge Design-Build Project Delivery Addressed

The Washington State Department of Transportation (WSDOT) considered traditional delivery options but decided that the design-build model was a perfect fit for this project because design-build did several things: it allowed fast-track delivery of the new bridge replacing a vulnerable structure, it allowed greater innovation and potential cost savings to WSDOT, and it shifted appropriate project risk components to the design-builder.

Summary

The SR 520 Floating Bridge and Landings Project designed and built the world’s longest floating bridge, creating a safer, more reliable link between Seattle and the growing high-tech cities east of Lake Washington. With HOV lanes, full shoulders for disabled vehicles, a cross-lake bicycle and pedestrian path, and the largest, heaviest, and strongest bridge pontoons ever built, the new, 1.5-mile-long floating highway dramatically improves the movement of people and freight in the Central Puget Sound region.
