The line runs south (upriver) on the west side of the Platte River to Lakewood Gulch. Prior to 2007, the line continued west along Lakewood Gulch (approximately West 13th Avenue) and ran on the old interurban shortline tracks of the Denver and Intermountain Railroad to Sheridan Boulevard. The line currently stops near where RTD built their new west corridor of the FasTracks light rail project, which opened on April 26, 2013. Future plans for the trolley include expansion into the planned redevelopment of Lower Colfax. On April 22, 2013, the Denver City Council approved the Sun Valley Neighborhood Decatur-Federal Station Area Plan; as part of the redevelopment of Lower Colfax, the Platte Valley Trolley will be extended all the way to the Decatur-Federal Light Rail Station.
