F Line (RTD)

The F Line was a light rail line, part of the rail system operated by the Regional Transportation District in the Denver-Aurora Metropolitan Area in Colorado.

Route
The F Line's northern terminus is at 18th Street in downtown Denver. It shares track with the D Line from 18th Street to I-25 & Broadway, then runs along the Southeast Corridor to Lone Tree.

On September 20, 2020, Regional Transportation District suspended the F Line due to the ongoing coronavirus pandemic. The line never returned to service and was officially eliminated ahead of the January 2023 service change.

FasTracks
The 2004 voter-approved FasTracks initiative included the Southeast Corridor extension for the E and F Line, which extended the lines by 2.3 mi to southern Lone Tree. The extension cost $223 million to construct and was opened on May 17, 2019. It included three new stations, Sky Ridge, Lone Tree City Center, and RidgeGate Parkway, the latter with a 2,000-stall parking facility.
