LEWISTON, ID - A system of radio transmitters relaying information to motorists on their car radio has reached the end of its life, and the Idaho Transportation Department says the state's Highway Advisory Radio communication system is being decommissioned. The use of the system was suspended on April 1. ITD is evaluating whether existing equipment and infrastructure can be repurposed to meet other needs.

There are 25 sites and 58 beacons located around the state, broadcasting emergency information on the am radio frequency. However, the equipment had reached the end of its useful life, and no longer met the technology security requirements of the state.

Surveys showed that the system, although once popular, was now ranked well behind other more viable sources for information distribution, such as calling 511 or roadside electronic message boards.
