Utah’s Transportation Department has just completed speed studies on several rural freeway sections and crews installed new 80 mph speed limit signs earlier this week.

The speed limit has been increased to 80 mph in several areas of the state.

Those areas are:

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

The speed limit increase is the result of a bill passed during the 2013 legislative session, which allowed the department to study and establish speed limits higher than 75 on interstate routes.
