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.

TBM Stuck on Pittsburgh North Short Connector Project
ENR reports that a Tunnel Boring Machine or TBM is stuck for the second time in two weeks on Pittsburgh’s light rail expansion project dubbed the North Shore Connector Project. As we described in a previous post, the project will consist primarily of a tunnel underneath the Allegheny River. The drilling began the week of March 3 and has been progressing at a rate of 30-ft/day or 5-ft/day faster than the original goals. Read on for a location map of the project, or download the Google Earth KMZ file showing the project area. (File photo of TBM)

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.
