A federal judge in Seattle dismissed a lawsuit Friday aimed at stopping construction of a tunnel replacement for the Alaskan Way Viaduct.
Judge John Coughenour said the people who brought the suit in September hadn’t established their standing. In his ruling he said they hadn’t specified how they’d be damaged by the lack of a full environmental-impact statement on all of the viaduct construction projects.

Devil’s Slide Tunnel Project Nearly Complete
The Devil’s Slide Tunnel Project was originally scheduled to open at the end of 2012, but it has been delayed slightly to an early 2013 opening. If you look at some recent photos, you can hardly tell that there is anything left to finish. I’ve been following this project since it started, since to me it represents the essence of geoengineering, with important roles played by geotechnical engineers, geological engineers, hydrogeologists, and of course geotechnical contractors and tunneling specialists. I thought it would be interesting to list a few of the posts I’ve written about the project over the years and present a bit of information I only recently learned. Click through for more.

New Water Supply Tunnels Underneath New York City
Urban miners have been busy constructing a new water supply tunnel underneath New York City to supply the megalopolis with the water it needs. The miners, or sandhogs as they are known, are about halfway complete with the new tunnel which is expected to be in service by the year 2020. Work on the 60-mile tunnel began in 1970 and the total projected cost is $6 billion and is widely regarded as one of the most complex public works projects in the western hemisphere. When complete, it will help deliver 1.2 billion gallons DAILY to 8 million New Yorkers. The city currently gets its drinking water from two water supply tunnels that were constructed in the early 20th century and have not been inspected or repaired since then. More after the break.
