The Green Line will be a new C-Train line stretch across the City of Calgary in Alberta, Canada, from North Pointe to the southeast community of Seton, adding 40 km to the existing 59 km LRT (Light Rail Transit) system. The northern part of the line will run on Centre Street. For the downtown link to connect the north end and the southeast portion the city examined five possible routes, with various combinations of elevated, street level, and underground routes for the Green Line. An evaluation of environmental sustainability, technical feasibility, cost, alignment with existing city policies, urban development, and public input led city staff to conclude Option D-full-tunnel route was the best way forward. An underground line will have fewer impacts to the transportation network due to its physical separation and will not limit future street-level development of the transportation network. On 18.04.2016 the announcement that the city is leaning toward the $1.8 billion full-tunnel route: the LRT line will run underground from 20 Avenue North all the way south to the Beltline in a tunnel beneath both the Bow River and downtown Calgary.  In the coming months, the Green Line team will explore three potential routes in the Beltline, using the same evaluation process as was used for the Centre City.
