LONE TREE, Colo. — Denver’s Regional Transportation District has opened a 2.3-mile extension of its light rail system, extending the Southeast Rail Line with three stations in Lone Tree.
The $238-million project, which opened Friday, is expected to spur development of 2,000 acres of mostly open land east of Interstate 25 — one reason Lone Tree and local stakeholders contributed $25 million to the project, the Denver Post reports. Construction of the extension began in 2015.
It is the sixth opening of an RTD service in a three-year period, which RTD General Manager and CEO Dave Genova called “unprecedented,” KDVR-TV news reports.
