ROY — The year’s first big road project is scheduled to begin this week on Interstate 15.
Utah Department of Transportation crews are set to start a project that will add an auxiliary lane on northbound I-15, between 650 North in Clearfield and 5600 South in Roy, a distance of about 4.5 miles.
UDOT Region One spokesman Vic Saunders said the first phase of the $7 million project will be conducted on the right shoulder of the freeway as crews work on the area around 1200 North.
Initially, lane restrictions will be limited, but the project will eventually impact traffic on the freeway.
The auxiliary lane will serve traffic flow between two Hill Air Force Base entry gates — the West Gate, which receives heavy daily traffic, and the Roy gate, where large shipping and equipment trucks enter the base.
The construction work will include installation of improved storm water drains and concrete traffic-control barriers, as well as the paving of the new asphalt lane.
Saunders said the project will be ongoing through the spring and summer and should be completed some time in September.
Auxiliary lanes are becoming a growing priority for the state. UDOT recently finished two new auxiliary lanes in Davis County, one in each direction on the interstate between Antelope Drive in Layton and Bernard Fisher Highway (State Road 193) in Clearfield.
The state also constructed a new auxiliary lane on northbound I-15 between 500 West in Bountiful and Parrish Lane in Centerville.
Saunders said the lanes benefit overall traffic flow because they allow people getting on the freeway enough time to build speed and give extra time to motorists getting off the freeway.
The freeway has similar auxiliary lanes in Layton near the Antelope Drive and Hill Field Road exits and in Ogden near the Riverdale Road, 31st Street and 12th Street freeway exits.
UDOT officials say the lanes have improved traffic flow in those busy spots.
