SALT LAKE CITY — Utah Department of Transportation crews canvassed the urban interstate across the Wasatch Front, replacing speed limit signs while officially changing the speed limit from 65 to 70 mph.
In an effort to optimize mobility and Keep Utah Moving, crews from UDOT Regions One, Two and Three spent all day on December 8th, changing out 99 signs from Spanish Fork to Ogden. In many instances, the crews simply placed a decal on the existing sign, but several of the older signs were replaced outright.
The speed limit increased on Interstates 15, 80 and 215. However, two sections of I-80 will remain at 65 mph, as engineering studies show the terrain doesn’t allow for a speed increase.
The choice to implement the new speed limits was based on several studies, and in response to last year’s legislation (H.B. 80).
Utah is not the first state to raise speed limits to 70 mph or faster. Nearly one-third of the United States has speed limits set at 70 mph or faster in urban areas, and more than two-thirds of states have increased them in rural areas.
