Based on ITA data, the yearly average of constructed tunnels is 3,200 miles, with expen- ditures in excess of $100 billion dollars in 2016. ertainly on the upswing. There are major rail and transit projects with under- ground components in the planning or design stages across the continent. The list includes the usual suspe os Angeles – but also Dallas, San Jose, C olis. De- mand is also high for sewer, water and highway tunnels. A quick look at some of the projects that may be coming out over the next decade includes several multi-billion projects, in- cluding: California WaterFix (shafts/tunnels >$7 billion), BART 2nd Transbay Tube ($12-15 billion); BART Silicon Valley Santa Clar erconduct- e B&P Tunnel (~$4.5 billion); ateway Tunnel (~$12-13 billion for tunnel and related structur cond Avenue Subway Phase 2 (~$6 billion); and the Hampton Roads Bridge-Tunnel (~$3.3 billion). Combined with "smaller" tunnel projects and programs throughout the continent, the future looks promising. Big Bores It is interesting to see in the wake of SR 99 project in Seattle, that agencies are not shying away fr or urban projects. Of cours erformed as expected after a long and costly delay due to a mechanical failure, so perhaps it is being viewed as a success story. bly, the Santa Clara Valley Transportation Authority (VTA) and the Bay Area Rapid Transit (BART) in April approved a plan to proceed with a single-bore tunnel as part of its expan- sion project into San Jose. Planners were deciding between using a large single bore or more traditional twin-bore tunnels under San Jose. The single-bore proposed for San Jose would use one 45-ft di- ameter tunnel b onstruct a 5-mile long circular tunnel structure. The boarding platforms will be con- structed one above the other inside the tunnel bore without con- struction disruption at the surface. This would be the first use of a large-bor or a subway proje In Calgary, planners are embracing a similar approach to the Green Line proje onstruct 2.5 miles of tunnel downtown. Project manager Paul Giannelia told the Calgary Herald that the single bore option could reduce dis- ruption as well as cost. To the east, two new highway tunnels will be using large diam- eter tunnels in place of immersed tube tunneling that had been the most prominent method in the past. Dragados/Schiavone will be using a 42-ft Herrenkne ore the 1-mile Chesapeake Bay Bridge-Tunnel, while in the Hampton Roads area, the Virgin- ia Department of Transportation selected the bored method over immersed tube. The project is currently in the bidding phase. There were plenty of other developments and exciting projects happening in 2018. We look forward to bringing you all the cover- et in 2019 and beyond!
