Interstate 84

SOUTH WEBER — The Utah Department of Transportation is wrapping up a study that could result in a new, multimillion interchange at the intersection of Interstate 84 and U.S. Highway 89.

During a recent Utah Transportation Commission meeting, Utah Department of Transportation Program Manager Nathan Peterson said the study, which cost $225,000, is looking at options to improve the current I-84 interchange at U.S. 89, near the mouth of Weber Canyon. Peterson said preliminary estimates suggest the work could cost as much as $66 million, but the project has not yet been funded.

The interchange may eventually be impacted by a large-scale reconstruction plan for U.S. 89.

UDOT plans to rebuild the highway along a 9-mile stretch between Farmington and Interstate 84 in South Weber, transforming the road into a six-lane freeway-type facility.

As part of the project, the road will be widened from four lanes to six, with signalized cross-street intersections eliminated and new interchanges added at 200 North in Kaysville, 400 North in Fruit Heights and at Oak Hills Drive, Gordon Avenue and Antelope Drive in Layton.

UDOT will also build two overpasses, crossing over Nicholls Road in Fruit Heights and Crestwood Road in Kaysville. The plan also includes new side roads, pedestrian bridges, a multi-use trail and bicycle improvements.

The project is valued at more than $473 million — a total that does not include the proposed interchange at I-84.

“Traffic is increasing there and that interchange was designed a long, long time ago,” UDOT Region One spokesman Vic Saunders said of the tentative project. “And with the U.S. 89 project, we know we’re going to deliver even more traffic to the area.”

A construction date for the U.S. 89 reconstruction has not yet been determined, though the state had originally planned to start sometime this year. The project is involved in an ongoing legal battle, which could possibly impact construction time frames.

Saunders stressed that the possible I-84 interchange is merely being studied at this point, with no funding currently tabbed for the project.
