Today on KUOW 94.9 FM's "The Conversation," Ross Reynolds and reporter Deborah Wang took on a comprehensive reporting assignment to look at the deep-bore tunnel--the transportation option chosen in 2009 by Seattle, King County and Washington State to replace the aging Alaskan Way Viaduct. 

Cascadia Center and Discovery Institute have been front and center on the idea of a deep-bore tunnel since the beginning of the debate. And Cascadia Center director Bruce Agnew provides an abundance of context and background for the KUOW report. 

KUOW's report summarizes the history, policy and dynamics of replacing an aging, elevated highway with a highly advanced and technical tunnel. Listen to the report here.
