Jefferson County is planning improvements to JC-73 between Buffalo Park Road and Plettner Lane beginning mid-2023. Benefits to the public will include:
- Safety enhancements to the intersection of Buffalo Park Road and JC-73;
- Left Turn Lanes;
- A Concrete Pedestrian Trail;
- Drainage and Flood Controls; and
- Bridge Replacements at Cub Creek.
The project will be funded in part with a grant of $8.75 million from the Federal Highway Administration (FHWA). Jefferson County's share is estimated to be $2.19 million.

Preliminary design and public outreach efforts were conducted throughout 2021. Final design is nearly complete and currently undergoing state and federal agency review. A public meeting was held on April 18, 2023 at Evergreen High School. A virtual option is posted below.

After receiving final clearances, the project will be advertised for construction bids. Construction is expected to begin in the fall of 2023 and continue into 2025. Construction is planned to progress from Plettner Lane to Buffalo Park Road in several phases. Traffic impacts should be expected throughout the construction project as JC-73 is reduced to a single lane, on and off, during daytime and evening work activities. Two lanes of traffic will be maintained during the peak hours of 5:30 a.m. to 8:30 a.m. and 3:30 p.m. to 5:30 p.m..
Utility Relocations and Site Preparation:
Xcel Energy crews will repair one more failed asphalt patch in the northbound lane of JC-73 near the Assist-2-Sell realty office (south of Little Cub Creek Road). Work will occur Tuesday, May 30 from 9:00 a.m. to 2:00 p.m.
Thank you for your patience as crews continue to work with the recent moisture damage to the roadway.
Stakeholder Engagement Process:
Public involvement and feedback provided in 2021 were incorporated in the final design. Jefferson County will continue to develop a public information plan to implement during construction. Efforts are currently underway to identify and incorporate the needs of Evergreen Schools, Evergreen Fire Department, Jefferson County Sheriff's Office, Evergreen Parks and Recreation, the Evergreen Chamber of Commerce, and area businesses. The information plan will focus on ways to: (1) Reduce traffic congestion, (2) Communicate planned work events, and (3) accommodate fire and emergency response. This plan will be implemented and refined throughout construction.
Evergreen Lake North Trail Project:
The county is coordinating with Evergreen Metro District and the Colorado Department of Transportation (CDOT) to mitigate the traffic impacts from construction of Evergreen Lake North Trail Project on JC-73 and CO-74. See Evergreen Park and Recreation District's project webpage, call the project information hotline at 720-356-4440, or email the project team to learn more.
Your feedback is valuable in the decision-making process. For questions, please email Transportation and Engineering.
