Plum Creek Boulevard and Crystal Valley Parkway Roundabout

In anticipation of the future construction of the new Crystal Valley Interchange and increased local traffic volumes, the existing intersection of Plum Creek Boulevard and Crystal Valley Parkway will be improved with a roundabout. This project will decrease congestion and increase safety for motorists along the corridor.  

The Plum Creek Boulevard and Crystal Valley Parkway roundabout is in alignment with the suggested roadway improvements along the southern corridor of Town, as identified in the Transportation Master Plan.

Project background

Town staff reviewed a variety of roadway improvement options to identify one that meets the most elements valued by the community: high safety, low lifecycle cost, low downtime, low environmental impacts, and reliability. The roundabout option was determined to be the most effective over traffic signal and stop sign options.

The project will implement the following:

  • Improved access to the new Crystal Valley Interchange from the southeast areas of Town
  • Bicycle lanes and improved pedestrian crossings
  • Reduced speeds at the intersection, which assists with improved safety

Project timeline

The roundabout design is scheduled to be complete by fall 2022. The construction phase is estimated to begin shortly after design completion. Construction is anticipated to be complete by summer 2023.
