Ridgegate Parkway Widening

The City of Lone Tree will widen RidgeGate Pkwy to provide 2 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-feet wide sidewalks (pedestrian) and a 12-feet wide cycle track (bicycles) along this corridor. A portion of the Project will utilize a split alignment.

This project is split into two phases. Phase 1 included the installation of two bridges and some earthwork has been completed.  Phase 2 includes the remaining roadway expansion and is expected to be substantially completed by June 30, 2020.
