Plans were recently announced for a $4 billion revamping and extension of the public transportation system in Ottawa.
"The city of Ottawa has unveiled its proposal for a revamped and extended mass-transit system that focuses on two light rail lines, buses, and a transit tunnel running east-west under the downtown core."
"If it goes ahead, work could take up to 23 years and cost as much as $3 billion to $4 billion. It would be, by far, the biggest construction project in the city's history."
"The proposal unveiled March 3 contains several options - mostly dealing with emphasis and scheduling - whether the first big push should be the tunnel, for example, or completion of the present bus transitway system, or development of a light rail system."
