Project Overview:

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.

Project Schedule:

Preliminary design and public outreach efforts were conducted throughout 2021. Final design is nearly complete and currently undergoing state and federal agency review. Additional public presentations of the final design will be scheduled for March 2023 for both virtual and public venues. Additional information and links to plans will be provided in the next month.

After final plan review, the project will be advertised for construction bids. Construction is expected to begin in the summer 2023 and continue through 2024. 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 during daytime and evening work activities.

Utility Relocations and Site Preparation:

Utilities are currently being relocated in advance of roadway construction. Gas main relocation and service connections in JC-73 have been ongoing since November 2022. Gas work is expected to be completed by the end of January 2023. Electric line relocations and improvements have also been started in areas east of JC-73 near Evergreen Library. Additional electric work in JC-73 will occur later this spring.

Site preparation will also commence in February as structure demolition across from Evergreen Fire Department occurs.

UTILIY RELOCATION UPDATE

Xcel crews continue to work on new residential gas line relocations in the vicinity of JC-73 and Buffalo Park Road.

Crews will temporarily shut down during the week of January 17, 2023 for winter snow storm conditions. Work is expected to resume during the week of January 23, 2023.

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 pan 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.
