It's another milestone in the long-awaited $1.4 billion SkyTrain extension known as the Evergreen Line — construction is starting on public plazas at several stations in Port Moody and Coquitlam, B.C.

Today, B.C.'s Community Minister Peter Fassbender was joined by other officials at a groundbreaking event for the public plaza at Inlet Centre Station, which will be completed this summer.

The plazas are designed to be welcoming, functional public spaces with places to sit, bike racks, landscaping and public art, according to a release from the provincial government.

At this point, the Evergreen Line is considered to be 85 per cent complete, with tunnel boring and tracks finished and many station buildings complete too.

Last September, the province said the 11 kilometre line would be finished by the end of 2016, but a few months later officials said it would be early 2017 before the line is in service.
