Signals will receive a variety of upgrades, including new or upgraded vehicle-detection systems, upgraded signal cabinets, control panels and electronic components, and several existing left-turn signals will be replaced with flashing yellow arrow signals.

Additionally, 69 signals throughout the Magic Valley will see replacement of the signal head back plates over the coming months.

Most of the work should be completed without delays or affecting the normal flow of traffic. Drivers are reminded to watch for short-term traffic control measures for the different operations, including shoulder and lane closures. Four-way stop signs and flagger-controlled intersections will be used if signals need to be shut off or put into flash mode.

Cache Valley Electric, of Salt Lake City, is the contractor for work the $802,000 project. Work is expected to be completed through the winter months.
