Ottawa, Ontario.
Ottawa is replacing a section of its Transitway (BRT) from Tunney’s Pasture Station (in the west) to Blair Station (in the east). Called the Confederation Line, it will consist of 13 stations and will be 12.5km long.
Construction is expected to be completed in late 2017 in honour of the 150th Anniversary of the Canadian Confederation. Service will begin in 2018.
Currently Transitway buses drive through mixed traffic through the downtown, resulting in a conga line of buses during peak. To mitigate traffic, (from west to east) a tunnel will go under Queen Street, curve northwards along Rideau Street and curve south along Waller Street. The downtown tunnel will have three stations; Lyon, Parliament, and Rideau.
A fourth underground station will be located at St-Laurent Station (a bus tunnel).
