By the end of 2022, pedestrians and cyclists will be able to utilize a 36-mile C-470 trail that connects users north to Golden and south to the Cherry Creek Regional Trail, all without having to cross the busy intersection of Yosemite Street and C-470 in Lone Tree.

In December 2021, Douglas County began a trail improvement project which included the installation of a pedestrian bridge with an extension of a multi-use trail and sidewalk on the north side of Yosemite Street and the C-470 off-ramp.

During construction, the existing trail access will be closed with a detour for users. The route will include Yosemite Street, Parkway Drive and will rejoin the C-470 Trail from both the east and west. Motorists can expect intermittent single lane traffic with flaggers directing motorists through the work zone Monday through Thursday from 7 a.m. to 5 p.m. and on Fridays from 7 a.m. until 2 p.m.

The bridge construction is expected to begin mid-year. During that time, there will be overnight full lane closures and full ramp closures.

“As a route organizer for our cycling club, I’m constantly seeking ways to avoid as many major cross streets as possible,” said Neil Alvarado, Castle Pines Cycling Club organizer. “This improvement helps our club’s goal of providing our riders with safer opportunities to ride.

In recent years, many cyclists have traded their road bikes for mountain bikes, partly to avoid dealing with cars. I’m encouraged to see Douglas County making this a priority for Coloradans. These projects will continue to reinforce our state’s reputation of being active and healthy residents,” Alvarado continued.
