New wind detection signs are going up along U.S. 395 in the North Valleys. NDOT’s work will mean shoulder closures in both directions of the highway from 6 a.m. to 5 p.m. weekends starting Tuesday and lasting until May 22nd. When it’s done, there will be six wind warning signs-three in each direction-between Golden Valley and Bordertown-that will flash when wind gusts reach 45 miles per hour or greater. Vehicles over nine feet will be advised not to travel.
