RIGBY - Reduced visibility caused by blowing dust has closed Interstate 15 between Idaho Falls and Roberts, the Idaho Transportation Department announced.

I-15 closed from milepost 119 to 134.5 at 3:08 p.m. today (Monday, April 29).

Northbound traffic is being detoured from I-15 to U.S. 20 in Idaho Falls and then from U.S. 20 in Rigby to Idaho 48, which runs to Roberts and I-15.

Southbound traffic is being detoured from I-15 to Idaho 48 in Roberts and then from Idaho 48 to U.S. 20 in Rigby, then south to I-15 in Idaho Falls.

The transportation department estimates the interstate will reopen late tonight, when the wind is expected to subside. The National Weather Service forecasts sustained winds of 35 to 45 mph this afternoon and evening, with gusts of up to 60 mph.

Motorists should drive with extreme care and observe traffic signs and signals. High winds make for highly dangerous driving conditions. Drivers are encouraged to visit 511.idaho.gov or call 5-1-1 for the latest highway conditions.
