RIGBY - The speed limit on Idaho 43 south of Ucon will be reduced starting Tuesday (June 18), the Idaho Transportation Department announced.

The speed limit immediately south of 105th North in Ucon will be lowered to 35 mph, while the speed limit one-third of a mile south of 105th North will be lowered to 45 mph. The speed limit one-half-mile south of 105th North will remain 55 mph.

Changes to the existing speed limit of 55 mph along the route stem from a speed study that shows motorists travel at speeds lower than 55 near 105th North because of traffic and accidents in the area.

Posted speeds are the maximum allowed under favorable weather conditions and supplement driver judgment of a reasonable speed under conditions that are less than ideal.

The Idaho Transportation Board approved the speed-limit change May 16.

Motorists should watch for road crews on the shoulders of the highway during sign installation.

Idaho State Police and local law enforcement officers will patrol the route during and after the transition.
