The state legislature has approved a deep bored tunnel to replace the Alaskan Way Viaduct, and Cascadia Center was instrumental in educating decision-makers. This recent article highlights our role. Read More ›
.....As recently as last December, the bored tunnel was dismissed as too expensive by the viaduct project team. But then the Washington State Department of Transportation realized it could build a tunnel with a single bore instead of a double bore, and the cost estimate fell by almost $900 million. “It's less labor, less materials, one machine versus two,” said John White, viaduct program director for WSDOT.
...Last year two 51-foot diameter tunnels were built in Shanghai, China, according to a report by Arup that was commissioned by the Cascadia Center, which is part of the Discovery Institute. A forceful advocate for the bored tunnel, Cascadia paid Arup $35,000 for that report, according to Cascadia's policy director, Bruce Agnew. In early December, while the viaduct project team was eliminating the bored tunnel from its list of possibilities to replace the viaduct, Cascadia brought together a group of tunneling experts who wrote a letter to WSDOT saying its cost estimates for the bored tunnel were too high. The group wrote to WSDOT Deputy Secretary David Dye and said a bored tunnel could be “completed in the 60 months period with a price of $2 billion or less.” That letter was authored by Richard Prust of Arup, Vladimir Khazak of HNTB, Dick Robbins of the Robbins Co., independent consultant Kern Jacobson and Gerhard Sauer of the Sauer Corp.
