Thousands of Calgarians rode the new west leg of the LRT to work on Monday morning.

The new C-Train line opened for commuter service at 5 a.m. MT, expected to carry 25,000 passengers along 8.2 kilometres between downtown and 69 Street S.W. in just 12 minutes.

Ridership is projected to grow to more than 40,000 passengers per day over the next few years, according to the city.

The new line cost $1.4 billion and was about three years in the making. The city says it is one of the largest infrastructure endeavours ever undertaken.

The inaugural run happened on Saturday morning, with politicians and City of Calgary representatives aboard.

During the celebrations, Alberta Transportation Minister Ric McIver also announced that in addition to the $332 million for the West LRT line, Calgary will receive $133 million for the purchase of at least 50 new LRT cars and $8 million for the pre-design of the Southeast Transitway project from GreenTRIP.
