RidgeGate Widening

Project Description

The City of Lone Tree will widen RidgeGate Parkway to provide two additional thru-lanes in each direction (between I-25 and Meridian Village Pkwy), building new bridges over Badger Gulch and Happy Canyon Creek, installing 8-foot wide sidewalks (pedestrian) and a 12-foot wide cycle track (bicycles) along this corridor. A portion of the Project will utilize a split alignment.

This Project is split into two phases. Map of RidgeGate Parkway expansion

Construction began in April 2019 and is anticipated to be substantially completed in Spring 2021.
