New Electronic Speed Signs
New electronic speed limit signs are in place along Interstate 80 between Laramie and Cheyenne. The signs make it possible for the Wyoming Department of Transportation to remotely change the speed limit on the highway to match current road and weather conditions. WYDOT has installed more than three dozen signs along I-80 in southern Wyoming.
The signs allow the speed limit to be dropped incrementally to as low as 30 or 35 mph, with the ability to tailor the speed limit changes to road sections as short as two miles in length. Statistics indicate that the signs, combined with other improvements in maintenance strategies, resulted in fewer crashes and road closures.
