The west leg of the LRT will be open for business in Calgary on Dec. 10.
The city says this date meets the original start of service promised back in 2009.
"We want to provide all Calgarians with the opportunity to make Calgary Transit their preferred transportation option and this project is a major step towards that goal," said general manager of transportation Mac Logan.
Officials estimate more than 30,000 people will be using the new LRT run, which includes six new LRT stations along more than eight kilometres of track.
Construction on the project began in February 2010.
Completing the project involved major roadway upgrades, construction of a new interchange and moving a high school.
"This project required a great deal of expertise and co-ordination — its success speaks volumes about the hard work and dedication of everyone involved," said Logan.
