A SkyTrain extension from Lougheed Town Centre station to Coquitlam Town Centre was proposed when the original Millennium Line was built and the necessary junction tracks for such an extension were built at the station during its initial construction. At one point prior to 2008, the mode planned for the extension was changed to light rail instead of SkyTrain, which meant that the junction tracks would have remained unused. However, in February 2008, plans reverted to the use of SkyTrain technology for the extension, to facilitate higher ridership, shorten travel times and to integrate seamlessly with the existing SkyTrain network. As a result, the junction tracks and roughed-in third platform at Lougheed Town Centre station were used as part of the Evergreen Extension.
