West LRT elevated guideway construction begins

The western skyline of downtown Calgary is about to change forever as construction begins on the elevated guideway for the West leg of the LRT.

The 1.5 kilometre long structure will be Calgary’s first elevated LRT guideway. It will feature Sunalta Station, which at 14 metres above ground will be Calgary’s first elevated LRT Station.

“Progress on the West LRT continues at a fast pace. The elevated guideway is just one of many components of the project which is making substantial headway,” said Mayor Dave Bronconnier.

Bronconnier, accompanied by Alana Delong, MLA Calgary Bow and Pierre Duhaime, President and CEO of SNC-Lavalin Inc., kicked off the construction of the West LRT elevated guideway today with the lifting of the first precast segment.

Since March 2010, the design-builder, SNC-Lavalin, and its partners have proceeded with roadworks and the relocation and installation of new underground utilities. Excavation work at Westbrook for the future underground station and along 17 Ave S.W. for the trench section and 45 Street Station is progressing.

The construction of the interchange at Sarcee Trail and 17 Ave S.W. is also underway. The new park and ride facility at Sirocco Drive opened in June 2010 while construction of the West Calgary High School is over 50 per cent complete and on schedule for September 2011 opening.

“Constructing the West LRT line will bring many benefits to Calgarians,” said Mayor Bronconnier. “It will be a safe, fast connection between downtown and west Calgary reducing traffic congestion. It’s an environmentally friendly alternative, which offers improved transit connections to a number of southwest destinations such Mount Royal University, West Hills shopping district and the future Westbrook Village Transit Oriented Development site.”
