......

In June, the Cloverdale Road overpass sustained extensive fire damage caused from a tragic crash on Interstate 84. As a result, the Idaho Transportation Department (ITD) will be replacing the overpass with a new structure. In coordination with this work, the Ada County Highway District (ACHD) will be improving Cloverdale Road between Franklin Road and Camas Drive.

Project Description

Overpass

ITD will replace the Cloverdale Road overpass with a wider bridge that will include:

  • Two lanes in each direction
  • Sidewalk, curb and gutter
  • Bike lanes

The structure will also have a higher clearance over I-84 and be built to accommodate a future fifth lane expansion of the Interstate.

Cloverdale Road

ACHD will redesign the approaches to the overpass to include:

  • Two travel lanes in each direction
  • A center turn lane
  • Sidewalk, curb and gutter
  • A raised bike lane
  • Upgraded school zone flashers
  • An upgraded pedestrian signal at Emerson Drive and Cloverdale Road
  • A wider bridge over the Ridenbaugh Canal

Schedule
While we anticipate moving quickly on this project, we are still in the initial stages of design. We expect to have roadway alignment and overpass design details to share with you in late summer. At that time we will know more about right-of-way impacts and what purchases will need to be made.

Once we have all the design details in place, the intent is to start construction as soon as possible. We expect construction could start as early as this winter, however timelines could change.
