Drivers on I-80 next week will see something no one has ever seen before on Nevada’s roads. 80 miles per hour speed limit signs. It’s a first for the Silver State. The new speed limit between Fernley and Winnemucca will be posted beginning early next week, but it will remain 70 or 75 miles an hour on other sections of I-80 due to the elevation changes near the mountain summits. Installation of the new 80 miles per hour signs starts this Monday May 8th.
