Mar 26 2019, 4:09 am

You may not see any tracks being laid quite yet, but the construction of Calgary’s newest CTrain line, the Green Line, is well underway.

According to a March 20 update, from the City of Calgary, the new transit line is currently facing two items that are at the forefront of planning: a four-kilometre tunnel through the downtown core and deciding where the line will extend to in future stages.

The tunnel is expected to run underneath the downtown core and Beltline, though the city still needs to determine whether they will be drilling a single-bore or twin-bore tunnel.

The update states that both construction methods are currently under review.

As for where the Green Line will go once its first stage is complete, the update stated that the committee will be “exploring different potential expansion options that are operationally viable and ready as funding becomes available.”

A Transportation and Transit Committee meeting will be held later this year to determine the Greet Line’s future stations and routes.

Construction projects across the city are currently underway in anticipation of the track being laid, and includes laying telecommunication infrastructure underground, moving shallow utilities underground, the temporary removal of the Jeffries Park playground, relocating utilities such as water and sewage from certain areas along the future track, and constructing a new road (90 Avenue SE) to connect 24th Street SE to Shepard Road SE.

The main construction of the Green Line is expected to begin in 2020.
