The SR 99 tunnel will replace the existing elevated highway that was in need of replacement in the wake of the Nisqually earthquake in 2001.

April 22-28, the World Tunnel Congress (WTC) will convene in San Francisco, marking the first time the International Tunneling Association (ITA) has held its annual event in the United States since 1996, when it was held in Washington, D.C. It is a time for the United States to showcase some of its many contributions to tunneling technology made over the past two decades.
For the past several years, we here at TBM have kicked off the New Year by inviting a panel of tunneling professionals to share their views on the North American tunneling market in the coming year(s). Most are in agreement that the market is still growing, albeit slower than in recent years and slower than in some other parts of the world.
