A Granite-led venture has won a $348 million design-build contract for the US-89 Farmington to I-84 project in Davis and Weber Counties, Utah.
Granite says the US-89 Farmington to I-84 project will improve safety and mobility on US-89 by widening the roadway as well as adding interchanges and bridges. This includes extending the existing frontage road system to help local traffic access new interchanges and crossings more efficiently, the company adds.
The scope of work includes the widening of nine miles of US-89 in each direction to three lanes, the addition of four interchanges and two grade-separated intersections. In addition, crews will excavate two million cubic yards of material and relocate 150 miles of utilities. Approximately 300,000 tonnes of hot-mix asphalt and 100,000 tonnes of base rock will be provided by Granite facilities.
The venture, Oak Hills Constructors, was chosen by the Utah Department of Transportation.
Oak Hills is a 60/40 joint venture with Granite and Ralph L. Wadsworth Construction. Construction is expected to begin in early 2020, continue into 2023.
