The Norwegian government wants to build a tunnel linking two fjords that would be large enough to pass 16,000 tonne cargo and passenger ships. The treacherous stretch of waterway has seen 46 accidents and 33 deaths since World War II. The 1.7 km Stad maritime tunnel would cost about 1.6B kroner ($274M USD).

Comments Off on 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)
