BOISE, Idaho — The Ada County Highway District held a ribbon cutting ceremony Monday morning commemorating the progress on the Cloverdale Overpass.

The overpass has been closed for a year after one of the worst interstate crashes in Idaho history. Almost a year ago to the day four people, including three Mountain Home airmen, were killed in a fiery seven-car crash in what was a construction zone under the bridge.

Now, one lane of travel in each direction is open. Construction during the summer will impact motorists until the project is finished.

This is a joint project between the Idaho Transportation Department and ACHD. ITD is replacing the overpass with a wider bridge with two travel lanes in each direction, bike lanes and a sidewalk.

ACHD is widening Cloverdale Road between Franklin Road and Camas Drive.

Work will be complete by September 2019.
