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. 

  • Phase 1 includes the two bridges and some earthwork.
  • Phase 2 includes the remaining roadway expansion and is expected to be substantially completed by Spring 2021.
