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.

RidgeGate Pkwy from Meridian Village to Peoria St. (both directions) will have shoulder closures with heavy construction traffic entering and leaving the roadway.

This is a City of Lone Tree Project – please contact Steve Fletcher ([email protected])
