Plans are moving ahead to bore a 3-kilometer (1.9-mile) tunnel just blocks from Parliament Hill as Ottawa joins other Canadian cities hoping light rail is the answer to downtown traffic jams and deep commuter frustration. The $2.1-billion construction project will bring a 12.5-kilometer (7.8-mile) light rail line to the Canadian capital. Construction is scheduled to run through 2018. The city claims the project will reduce downtown bus traffic by 50% and reduce the city’s greenhouse gas emissions by 38,000 tonnes (42,000 tons) per year.
