Utah is making plans to rebuild a 7-mile stretch of Interstate 15 along the divide for Salt Lake and Utah counties.
The Utah Department of Transportation says the Point of the Mountain is last major stretch of I-15 that hasn't been improved in about 50 years, and it was prone to buckling in this summer's heat.
The $247 million project will start in spring and take nearly two years to complete.
Contractors will widen I-15 to six lanes from four or five and replace bridges at the Bluffdale interchange.
UDOT is assembling a project team to issue bid documents. It plans to select a contractor by early 2014. Highway planners say the goal is to maintain freeway capacity during construction.
