Bridges now open
Trail improvements increase safety, mobility near Park Meadows

A new Douglas County trail improvement project began on Dec. 13, 2021. Designed to improve safety along the trail, the project includes the installation of a pedestrian bridge with the extension of a multi-use trail/sidewalk on the north side of S. Yosemite Street and the C-470 on-ramp.

The old trail required pedestrians and cyclists to cross at the busy intersection of Yosemite and C-470. With the construction of the new overpass, the trail is rerouted over the intersection, creating a safer, more convenient connection for pedestrians and cyclists. Additionally, the new pedestrian bridge will improve mobility by reducing congestion and traffic delays on Yosemite Street related to C-470 trail users interfacing with motorists.

The total project is estimated at $5.5 million. The County was selected to receive $2 million in federal funds through the DRCOG project selection process.
