Canada Line\'s tunnel boring machine (TBM) achieved another milestone on Tuesday, April 7, 2007 when it broke through the ground north of Pender Street at Granville, the future site of the Canada Line Waterfront Station.The arrival of the TBM into the Waterfront Station excavation pit marks the completion of the first of two bored tunnels beneath downtown Vancouver.\n\nThe TBM will now be disassembled and transported back to the 2nd Avenue worksite near False Creek to start the second tunnel, which will be completed in the spring of 2008.\n\nThe first tunnel is 2.5 kilometres long and has taken 10 months to complete. Approximately 10,000 pre-fabricated concrete lining segments have been used to make the tunnel walls. The tunnel is 5.3 metres in internal diameter and varies in depth between 10 and 30 metres.\n---------------------------------------- --------\nAt a length of nearly 19 km, the Canada Line will be an automated rapid transit rail service connecting Downtown Vancouver with central Richmond and the Vancouver International Airport -- linking growing residential, business, health care, educational and other centres in the region -- and adding transit capacity equivalent to 10 major road lanes. The Canada Line will connect with existing rapid transit lines at Waterfront Station and major east-west transit services, creating an enhanced transit network to serve the region in time for the 2010 Winter Olympics.\n\nThe line is expected to carry 100,000 passengers per day at launch and 142,000 passengers by 2021. Travel times southbound from downtown Vancouver will be 25 minutes to Richmond Centre and 26 minutes to the airport terminus. Northbound, trains will leave Richmond City Centre and YVRevery six minutes heading to Vancouver. The departures will be coordinated to allow for a train every three minutes on the main line in Vancouver. 2010, breakthrough, canada, line, olympics, rail, rapid, station, subway, tbm, transit, translink, tunnel, vancouver, waterfront
