City council has approved the Centre Street Green Line alignment option that would link the northern and southern segments through an underground tunnel.

At the center of the debate was the $1.95-billion dollar price tag.

The Green Line tunnel would begin at 16th Ave north to just south of the CP Rail tracks and feature three underground stations.

The cheapest option was $450-million less and would have seen the LRT travel over the existing Centre Street Bridge.

There is uncertainty around how the project will be funded, since higher levels of government have yet to voice a solid financial commitment.

A final decision, based on available funding dollars, is expected to be made in June of next year.
