Canada Line on Track to Meet Olympic Deadline

In this article, the construction of the new Vancouver rapid transit's Canada Line that will shuttle persons from that city's downtown to the international airport is discussed. The line, set for completion prior to Vancouver's hosting of the 2010 Winter Olympic Games, will use 2.45 kilometer parallel tunnels with excavated stations throughout the heart of the city. The tunnel boring machines (TBM) used to excavate these tunnels are herein described. The TBM advance will be followed by a lining of rebar reinforced precast concrete at a 250 millimeter thickness. The excavation has had to change elevations and gradations a number of times, which are needed to clear the foundations of a number of high-rise buildings that are overhead. The TBM's progress is described positively. The article closes with a description of a cut and cover project for the same line that will house 7 kilometers of track.
