The bridge was severely damaged and will be replaced with a higher-capacity structure
The Ada County Highway District and Idaho Transportation Department are constructing improvements to Cloverdale Road between Franklin Road and Camas Drive.
In June 2018, the Cloverdale Road overpass sustained extensive fire damage caused by a deadly crash on Interstate I-84. The Idaho Transportation Department (ITD) and the Ada County Highway District (ACHD) are partnering on the design and construction of the new bridge and roadway to address the long-term needs of the community.ACHD's full project (road and bridge) website
The new bridge will feature:
- Four 11-foot travel lanes for vehicles
- 2-foot shoulders
- Two 13'6" multi-use pathways for bicycles and pedestrians
- Protective fencing on top of bridge rails
1. What are the travel impacts to the public?
Cloverdale Road will remain closed between Franklin Road and Camas Drive during construction. There will be nighttime closures of I-84 between Eagle Rd. and the WYE interchange at critical milestones as the overpass is rebuilt. The public and media will be notified in advance of any closures and traffic will be detoured.
2. Why aren't ramps being added to the bridge for access to I-84?
Adding ramps at this location - turning the overpass into an interchange - would impact the entire roadway network in the area. Most importantly, it would reduce safety and mobility on I-84. Before such features would be constructed, extensive analysis is required to see if improvements on the local system and/or existing interchanges can improve traffic safety and mobility.
3. Are noise barriers being built as part of the project?
Noise barriers, also called soundwalls, are not being constructed as part of the project. Reconstructing the new overpass bridge at Cloverdale is essentially replacing what was there prior to the crash in June 2018 and will not result in a significant change in traffic volumes, patterns, or noise.

Crews have installed the girders for the replacement bridge and will soon begin to lay the deck on top of them.
