New 80 MPH Speed Limit on Nearly 300 Miles of Utah Roadways

In a week or so — or as soon as work crews get the speed limit signs installed — drivers on certain roadways in Utah will be able to drive 80 miles per hour, thanks to House Bill 83, just approved by that state’s legislature, adding a total of 289 miles of roads with the new speed limit.

That bill — which followed an extensive study by the Utah Department of Transportation (UDOT) — established speed limits exceeding 75 mph on portions of Interstates 80, 15 and 84.

Areas included in the higher limit include:

  • Interstate 80, from the Nevada border to state Route 36
  • Interstate 15 between North Leeds and Santaquin (with sections of 75 mph zones through two mountain passes and Cedar City)
  • Interstate 15 and Interstate 84 from the Brigham City North Interchange to the Idaho border.

The St. George News said UDOT’s data from speed studies of existing 80 mph zones showed that vehicle crashes have dropped slightly over the past three years. It attributes the drop to more vehicles traveling at the same speeds and less variation in the speed of surrounding vehicles.
