The excitement is building: the State Route 99 tunnel is still on track to open to traffic next Monday Feb 4. This Saturday & Sunday, some 100,000 people are expected to take part in a fun run, a bike ride and a walk (that would be me), through the tunnel.
It’s been a long arduous time since Oct. 2011. That is when part of the south end of the Alaskan Way Viaduct was demolished to establish the south portal of the tunnel, and install the ‘Bertha’ tunnel borer. Then there was the breakdown of Bertha in Dec. 2013, after just 1,000 ft of boring. After all the setbacks, though, the cost overrun on a $3 billion project was only in the hundreds of millions. (These infrastructure projects are notorious for huge cost overruns. The Boston Big Dig started out as a $3 billion project, and ended up costing some $15 billion).
