Lone Tree Overpass Project
Improving mobility and safety with a new north-south roadway connection extending Lone Tree Road between Butler Avenue to the south and Route 66 to the north.
Preliminary Overpass Design & Proposed Improvements
The project team is currently working on final design completion with agencies and stakeholders. Design is anticipated to be complete by end of 2023. The public will continue to see field activities including utility locating and demolition of structures through the end of the year. A public meeting to discuss construction activities will be planned for early 2024.
The City of Flagstaff will be holding two public meetings to provide updates of the design and the Economic Impact Study and get input on project details including opportunities for public art, landscaping, and spaces for rest and recreation.

The project team will use the recommended alignment from the 2010 Lone Tree Overpass Study and the 2020 Final Report Update as the initial design concept. This base concept will be refined, stakeholder coordination will occur, and the right-of-way impacts will be refined. The design will begin in phases and will progress as stakeholder agreements are obtained and design decisions are made with the public and stakeholders.
