Lougheed Town Centre station was opened in 2002 as part of the original Millennium Line project.
[2] An unfinished third platform had been roughed in on the east side of the station during its construction, in anticipation of a future connection for a SkyTrain extension to Coquitlam.
The provincial government suspended plans for the extension in the early 2000s, and in the interim TransLink decided to use light rail technology for the alignment instead of Bombardier's Advanced Rapid Transit technology (as used on SkyTrain's Expo and Millennium Lines), which would have rendered the roughed-in platform and the adjacent switches obsolete.
In 2012, construction began on the Evergreen Extension, which included the third platform at Lougheed Town Centre station.
[4] When the Evergreen Extension opened on December 2, 2016, Lafarge Lake–Douglas station became the eastern Millennium Line terminus.
