The State Route 99 tunnel, also known as the Alaskan Way Viaduct replacement tunnel, is a bored highway tunnel between Downtown Seattle and Lake Union, stretching two miles. It was deemed to be failing and the fear of an earthquake placed priority on a solution in 2009, due to the weak infrastructure.

The City of Renton was needing a main sewer line cleaned, inspected, and remnants transported and disposed of. The big challenge of this project was that the line was five to twenty feet under water in Lake Washington. There was also the installation of coffer dams to install new pipe access points. Coffer dams are a unique environmental and engineering challenge to ensure the work crews will have a dry work area for the install.
Customers: City of Renton, Tetra Tech Engineering and Ballard Marine
