Freeze-thaw cycles prompt speed, weight restrictions on state highways in eastern Idaho starting Monday
RIGBY - Freeze‑thaw cycles prompt speed and weight restrictions on state highways in eastern Idaho starting Monday (March 8), the Idaho Transportation Department announced.
The first restrictions will be on Idaho 22, which runs between its junction with Idaho 33 nine miles northeast of Howe and Dubois (milepost 24 to 68).
The speed limit for trucks on this two-lane road will be 30 mph, with a weight limit of 16,000 pounds per axle or legal weights, whichever is less.
Speed and weight restrictions do not apply to emergency vehicles and school buses.
Transportation department officials will place restrictions on other highways in eastern Idaho later in the spring.
Speed and weight restrictions reduce pavement deterioration caused as roads soften from thawing in and beneath the pavement with the onset of warmer temperatures.
Restrictions will be in place until further notice and posted on the Idaho Traveler Services Web site and phone system: 511.idaho.gov or 5-1-1 from phones within the state. Outside Idaho, dial toll-free (888) 432-7623. Information is updated as conditions change.
