The Utah Department of Transportation is raising speed limits on four interstate highways, with some changes going into effect Wednesday and others by June 1.
For one of them - I-70, where changes seem inevitable - officials have not yet worked out details of the new limits.Changes were approved after the department conferred with the Utah Department of Public Safety, the Utah Transportation Commission and municipalities throughout the state, said UDOT spokeswoman Andrea M. Packer.
Utah's only freeway not affected is I-215. Officials cautioned drivers that because sign-changing may take some time, they must obey the posted limits until the new signs are up.
Changes are:
- I-15: 75 mph south of Spanish Fork and north of the 12th Street exit in Ogden. It will remain at 65 mph between those two points.
- I-80: from the Utah-Nevada border to 5600 West in Salt Lake County, 75 mph; from there to Wanship, Summit County, 65 mph; from Wanship to the I-84 interchange at Echo, Summit County, 70 mph; from Echo to the Wyoming border, 75 mph.
- I-84: from the Utah-Idaho border to I-15 junction near Tremonton, 75 mph; from I-15 junction near Riverdale, Weber County, to the Mountain Green interchange in Morgan County, 65 mph; from there to I-80 junction at Echo, 70 mph.
Changes under consideration for I-70 are from the I-15 junction near Cove Fort to a point eight miles west of Utah Route 24, 75 mph; from there to the junction of U-24, 60 mph; from the junction of U-24 to the Colorado border, 75 mph.
