The Utah Department of Transportation has chosen a consortium led by Kiewit Construction and W.W. Clyde Construction to build a new east-west alternative to Main Street in Lehi.

The $380 million road, called Pioneer Crossing, will stretch from Redwood Road in Saratoga Springs through Lehi at about 1000 South to Interstate 15 in American Fork. It will link to the freeway with a first-in-Utah "diverging diamond interchange," a European-style interchange that speeds traffic through with only two traffic signal phases instead of the three or four at other interchanges.

"Pioneer Crossing is intended to address a real transportation need in northern Utah County for additional east-west alternatives," project manager Bryan Adams said.

The companies will design and build the project, and major construction will likely begin in January. The road is expected to be completed from Redwood Road to Lehi next November, with the rest finished by fall 2010.
