2025 Project Highlights

Construction Update | Sept. 4, 2026

Labor Day Holiday 

To accommodate holiday traffic, construction activities will pause from Friday, Sept. 4 at 12 p.m. though Tuesday, Sept. 8 at 7 a.m. During this period, all travel lanes will be open. 

10,000 Tons of Asphalt - and Counting!

Crews have placed approximately 10,000 tons of asphalt as part of the roadway restoration work in Logan Canyon to date. That's more than 20 million pounds, the equivalent of approximately 400-500 typical asphalt truckloads.

Conduit installation along US-89 in Logan Canyon will provide a protected pathway for the new fiber-optic line. 

CAUTION: CYCLISTS

Construction activities are continuing near the mouth of the canyon. Cyclists are reminded to stay out of active work zones, follow posted signage and lane directions through the lane closures. The work zone contains heavy equipment and active construction operations. Entering the work zone can result in serious injury. 

Upcoming Construction Activities

Following the Labor Day holiday, crews will resume conduit preparation, fiber installation, and remaining roadway crossings throughout the project area. Crews will continue approximately 13 miles of underground conduit to make sure it is clear and ready for the new fiber line. They will also complete roadway crossings that connect to the conduit to junction boxes and communication equipment on the opposite side of the highway. Paving and restoration of impacted areas will continue as work progresses.

Lane closures will be present as work continues in the following locations:

• Milepost (MP) 466 to 467 (Near Guinavah-Malibu Campground)
• Milepost (MP) 480 to 482 (Near Tony Grove)

Travel Information:

• Drivers can expect additional delays due to heavy traffic flow going through the canyon
• Drivers can expect no lane restrictions every weekend
• No shoulder work is scheduled, allowing for normal travel conditions outside of intermittent work areas listed above
• Travelers may encounter impacts from other UDOT projects in the area 

Please slow down, watch for crews and equipment, and follow all posted traffic control through the work zone.

CAUTION: Motorcyclists, Cyclists, and Drivers

There are trenches, uneven road surfaces, and loose gravel throughout the corridor. Please use caution and prioritize safety while travelling through the construction area. Reduce speed, follow posted signage, and be alert of crew members and equipment.

The project is utilizing one-way traffic systems to manage vehicle flow through the work zones. Drivers utilizing turnouts within the project area are advised to wait until seeing vehicles traveling in the same direction of your destination before safely re-entering the travel lane.
