Downtown Eagle Mobility Improvements: Eagle Road and State Street
This project is substantially complete.
The Eagle Road and State Street intersection is the gateway to the City of Eagle and an important part of the downtown core. As a gateway, it serves vehicles, bicyclists and pedestrians of all ages who want to access local businesses, neighborhoods, the elementary school, and the senior center.
The Ada County Highway District (ACHD), working with the City of Eagle, is currently designing improvements to Eagle Road and State Street and the connecting roadway network which includes Olde Park Place, Plaza Drive and Aikens Street.
Goals
The goal of the street network improvements is to improve safety and mobility for all users while accommodating future traffic growth and creating a welcoming downtown environment.

Begins Tuesday, September 2EAGLE — Beginning Tuesday, September 2, the intersection of Eagle Road and State Street (Old State) along with westbound State Street (Old State) between Eagle and Olde Park Place will reopen as a controlled three-way stop as crews move into the final phase of the Downtown Eagle Mobility Improvements project.
As part of this work, State Street (Old State) will be closed between Eagle Road and 2nd Street. Drivers can use Plaza Drive to the south or East Idaho Street to the north to get around the closure. (See detour map.)
Access to local businesses will remain open throughout the closure.
This work is part of ACHD’s Downtown Eagle Mobility Improvements project, which is expected to wrap up this Fall.
All work is weather dependent.

History
The design was the outcome of the Eagle Road and States Street Concept Design, an effort that began in 2012. After working with the community and the City of Eagle to evaluate multiple alternatives, the ACHD Commission approved the City's request to design and construct the Quadrant Alternative. This alternative best balances the need to safely accommodate the expected traffic growth, minimize impacts to adjacent properties and parking, and make downtown Eagle more walkable and bikeable, as well as being respectful of downtown's history and small town feel.
