Eckert Road Bridge and Intersection Project
Eckert Road is an important corridor helping people get to nearby neighborhoods, Barber Park, the Greenbelt, and the Boise River. To make travel safer and easier, ACHD is planning several improvements in this area.
The project includes building a new Boise River Bridge that will serve everyone—drivers, walkers, and bikers—for many years. ACHD will also build a new bridge over the Ridenbaugh Canal and add a roundabout at the Boise Avenue and Eckert Road intersection.
The project is on an accelerated schedule due to the aging bridge structures and construction is anticipated to begin Fall 2026.
Project Highlights
- Construct new bridges over the Boise River and Ridenbaugh Canal.
- Add a multi-use pathway for pedestrians and bicyclists on the west side of Eckert Road between the Greenbelt and Boise Avenue.
- Add a greenbelt tunnel under Eckert Road to connect the existing and future Greenbelt and the Dallas Harris Legacy Walkway.
- Update the Barber Park driveway access.
- Construct a single-lane roundabout at Boise Avenue and Eckert Road with Rectangular Rapid Flashing Beacons (RRFBs).
Project Coordination and Funding
ACHD has coordinated with local, state, and national agencies and conservation easement holders to avoid or mitigate impacts to wetlands, wildlife, and conservation easements.
ACHD is also partnering with the City of Boise. The City is funding the Greenbelt Underpass portion of the project, supporting safe and continuous access along the Boise River Greenbelt.
The Boise River Bridge portion is funded through state funds administered by the Local Highway Technical Assistance Council (LHTAC) via the Leading Idaho Local Bridge (LILB) Program.

Your commitment to investing in Idaho’s aging infrastructure through the Local Highway Technical Assistance Council (LHTAC) is a testament to your vision, leadership, and unwavering dedication to the communities we serve.
A prime example of the impact of this initiative is the funding provided for the reconstruction of the Eckert Road Bridge—an essential connection for residents, businesses, and emergency responders in Ada County. Originally scheduled for replacement in the coming years, recent inspections revealed rapid deterioration, making an accelerated reconstruction imperative. Thanks to the funding made available through the Leading Idaho Local Bridge Program, we can expedite the replacement of this critical bridge while minimizing disruptions to other essential infrastructure projects throughout the county.
The significance of this investment cannot be overstated. Infrastructure is the backbone of our communities, facilitating economic growth, safety, and connectivity. By prioritizing the replacement and improvement of Idaho’s bridges, our state leaders have demonstrated a deep understanding of the long-term needs of a growing population. Their foresight ensures that our bridges remain safe and functional, supporting Idahoans today and for generations to come.
This proactive approach to infrastructure funding is a model of responsible governance—one that acknowledges the importance of maintaining and enhancing critical the transportation network, ultimately protecting the safety of the public. The ability to address essential bridge repairs and replacements in hundreds of communities large and small, reflects the wisdom and responsiveness of Idaho’s leadership.
On behalf of ACHD and the residents we serve, we thank you for your continued support, partnership and commitment to strengthening Idaho’s transportation system. The Leading Idaho Local Bridge Program is not just an investment in infrastructure—it is an investment in the future of our communities, our economy, and our shared prosperity.

We are pleased to share that the Local Highway Technical Assistance Council (LHTAC) has voted to accept and fund ACHD’s application for the Eckert Road Bridge replacement under the Leading Idaho Local Bridge Program. This means that both the design and construction costs for the new bridge will be covered by state funds set aside specifically for projects like this. ACHD will work closely with LHTAC as they administer the contract to ensure this critical project moves forward efficiently.
At this time, we are still working to determine the exact dollar amount of funding that qualifies for the project. Additionally, we do not yet have a finalized timeline for reconstruction, but we will provide updates as soon as more details are available.
ITD and ACHD are also looking into potential interim solutions that could reinforce the bridge while planning for its replacement. ACHD staff will fully explore its feasibility and potential impacts. More information on this will be shared next week.Finally, we want to remind the public that Barber Park remains accessible. The entrance to the park is open, and we have provided an updated map to show the location of access into the park.ACHD appreciates the patience and support of the public as we work through the next steps. More updates will be provided as information becomes available. Please continue to check this page for the latest developments.Eckert Bridge – February 7 Update

ACHD has announced the immediate closure of the Eckert Road Bridge following findings from a recent inspection that revealed widespread structural decay.
A press conference will be held today, Friday, January 31, at 3 p.m. in the auditorium at ACHD headquarters (3775 N Adams St) in Garden City to discuss the situation with media. Members of the media who would like to participate must RSVP to communications@achdidaho.org.
Following findings from an inspection report, ACHD was informed of significant deterioration affecting the bridge's load capacity. Specifically, the consultant’s assessment found moderate to severe decay on 22 out of the 48 bridge pillars. Additionally, on the center pier, five out of six timber piles exhibited severe decay.
Based on these findings, the Idaho Transportation Department recommended an immediate weight restriction of three tons. In the interest of public safety, ACHD has opted to close the bridge to all motor vehicle traffic, effective immediately. The bridge will remain open to bicycle and pedestrian traffic.
This morning, the ACHD Commission held a special meeting to approve the bridge closure. A link to the meeting is available on ACHD’s website for public access.
ACHD installed road closure signs along the bridge today, and will install advanced warning signage to help commuters navigate alternate routes.
The duration of the closure remains uncertain. ACHD will provide more information to the public on the timeline as it becomes available.
For further updates and detour information, please visit achdidaho.org/eckertbridge.
STREAMING INFORMATION: The meeting will be livestreamed and can be accessed at achdidaho.org/live for those who wish to watch virtually. The meeting will also be posted on ACHD's website and YouTube.January 31, 2025 | 2:30PM
