"We're going to work to make as much of that happen at night as we can," Pope said. "Unfortunately, we do have some residential areas that will be a little bit impacted by the noise, so we are limited in what we can do there at night."

All of the asphalt — on the road, shoulders and on- and offramps — will be replaced.

UDOT will be do similar preservation work on a four-mile stretch of I-84 between U.S. 89 and the Mountain Green exit. Ten- to 15-minute delays are possible as traffic there also will be restricted to one lane in each direction.

And between Mountain Green and Morgan, UDOT will complete a $25.5 million project it began last year on an 11-mile segment. Fifteen- to 20-minute delays are possible.

• I-15, at U-232 — Interchange, ramp and signal improvements are planned for the Hill Field Road interchange.

"Right now, it's a very congested area. The signals are not tied together; they are not coordinated real well," Pope said. "So we're putting in some state-of-the-art coordinating ability at the interchange to go from the frontage road on the west side of I-15 up into Layton."

Additional lanes will be added and the intersection's turn lanes will be modified to improve traffic flow and safety. Because the area is used extensively during the day, all work will be performed at night.

• I-15, exit 332 — The I-15 interchange at Antelope Drive/Syracuse Road will be enhanced with ramp, turn-lane and signal improvements. No restrictions will be in place during peak hours, but there will be "moderate delays" through the area, Pope said, during off-peak hours.

Pope said the improvements at the Antelope Drive and Hill Field Road exits will not take place at the same time. Most likely, he said, the contractor will complete the Hill Field Road project first.
