2025 Project Highlights

Construction Update | November 20, 2025 

Upcoming Construction Activities 

All activities on US-89 are paused for the winter season. Construction is scheduled to resume in early Spring 2026, as soon as weather conditions permit.

During the Winter Months

• The corridor will be routinely maintained
• Crews have removed all traffic control lights throughout the canyon
• Pothole repairs or other roadway maintenance may occur due to winter conditions
• If you observe any concerns along the corridor, please contact the Public Involvement Team using the information below.

Please note: This will be our final email update for the winter season. Our hotline and email will continue to be monitored throughout the winter months.

CAUTION: Motorcyclists, Cyclists, and Drivers

The project is not yet complete and additional roadway improvements are still needed. Please drive carefully in snowy or icy conditions throughout the canyon, and use extra caution around snowplows during the winter months.

2025 Fun Facts

The project team has been hard at work! See the information below for some fun facts about the project this year.

• 22 crew members installing conduit on the field and approximately 48 team members behind-the-scenes
• 325 junction boxes installed
• 700 feet of directional drilling completed under the Logan River
• Approximately 28 miles of conduit installed (including different depths of trenches)
• Clean fast rock saw operation – 26" deep, 88,000 feet (fiber only)
• Rock saw trench – 48” deep, 16,000 feet (fiber + Rocky Mountain Power)
• Primary running line – 60” deep, 10,000 feet (fiber + City of Logan Power)

How does weather impact paving activities?

Weather plays a crucial role in paving operations. Paving requires stable and favorable conditions to ensure that asphalt properly bonds with the ground and reaches the right density.

When conditions are too cold or fluctuate significantly, the asphalt can cool too quickly, leading to issues like cracking, erosion, and reduced pavement durability. For this reason, paving schedules are carefully planned around optimal weather periods to ensure long-lasting, high-quality roads.

What is HDPE Conduit?

High-density polyethylene (HDPE) conduits deliver a powerful blend of flexibility, strength, and reliability—making them a top choice for underground cable installations. Whether it's powering homes, connecting internet lines, or supporting utility networks, HDPE has become one of the most widely used materials for cable protection—and for good reason.

• Superior Flexibility – Unlike rigid materials that crack under pressure, HDPE bends and flexes with the ground. It can handle shifts from frost, earthquakes, or construction without breaking—making it a dependable choice for long-term use.
• Thermal Stability – Withstands temperatures as low as -75°C without becoming brittle or losing ductility. At the other end of the spectrum, HDPE conduit can be rated to operate in temperatures up to 105°C. 
• Waterproof and Chemically Resistant – HDPE doesn’t rust or corrode. It stands up to moisture, chemicals, and harsh soil conditions, keeping cables safe and dry for years to come.

Why is the conduit coming out of the road?

You might notice some colorful tubes or exposed conduit during construction– that’s all part of building the fiber optic network. The tubes contain the actual fiber optic lines that connect to internet services. They’re brought to the surface at key spots so technicians can carefully join them together or link them to equipment like distribution boxes or service points for easier access.
