E Line (RTD)

The E Line is a light rail line which is part of the rail system operated by the Regional Transportation District in the Denver metropolitan area in Colorado. The line was added to the system on November 17, 2006, with the completion of the Southeast Corridor as part of the T-REX Project. It is one of four routes that are part of the RTD's service plan for the corridor.

Currently, the E Line is operating at a 60 minute headway due to repairs of the coping panels on the Southeast Corridor. This is a reduction from the line's typical 15 minute headways.

Route
The E Line's northern terminus is at Union Station in downtown Denver. It shares track with the D Line from Union Station to I-25 & Broadway, then diverges by a level junction onto a flyover, and then parallels Interstate 25 from there to Lincoln Avenue in Lone Tree. On May 17, 2019, it was extended south by 2.3 mi to RidgeGate Parkway station in Lone Tree.

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 1,300-stall parking facility.
