Many Calgarians say construction can't start soon enough on the newly-approved Green Line.

The city's next bus-only transitway will run from the city’s far north to the new hospital in the far south and is expected to shorten the commute for about 400,000 people.

"The impact on my life would be daddy would be home sooner, so that would be a good thing," she laughed.

Council voted Wednesday to use $52 million from 2015-2024 to fund the project.

It's being touted as the next best thing to an LRT line.

"But with rubber tires, so to speak, where they can move a lot quicker through the city without delay in a more reliable manner," said Calgary Transit director Doug Morgan.

Buses could avoid usual traffic congestion

The first stage would allow a bus-only lane that would avoid the usual traffic congestion.

It runs from Harvest Hills in north central Calgary through the core out to the southeast community of Seton.

The city says it could eventually be converted into an LRT line.

The new transit line is expected to cost the city $764 million, but costs would escalate even more if the LRT conversion happens.

Because the project wasn't the top priority in the 30-year RouteAhead plan set out by the city, it means other transit projects can go ahead in the near future.

Transportation planners are already moving ahead with mapping out the new line and work could begin as early as next year.

Here is a map of the three proposed stages for the transitway:
