In an effort to improve traffic flow and safety at the intersection of state Route 39 (SR-39) and Main Street (100 South) in Huntsville, we have built a new roundabout.

The new roundabout features a free right-turn (no stop required) for northbound SR-39 traffic to eastbound SR-39 towards Monte Cristo. Also, a little larger roundabout design than is typical was built to accommodate larger recreational traffic and trailers that travel frequently through the area.

The project makes history as the first roundabout built on a state road by UDOT’s Region One, which includes the six counties north of Salt Lake City.

*Construction schedules are subject to change due to weather conditions, equipment/supply issues and other unforeseen circumstances.

• The SR-39/Main Street intersection is open to all-way traffic in the new roundabout configuration.
• The speed limit approaching the intersection has been reduced to 20 mph. Please reduce speeds and use caution while navigating the roundabout. 
• Ogden Valley pedestrians and cyclists are advised that the Pineview Loop Path has reopened on the northwest corner of the Main Street (100 South) and SR-39 intersection in Huntsville.
• Construction is wrapping up for the winter season. Crews will return in spring 2026 to complete a chip seal on the new asphalt surface, final roadway striping and right-of-way fencing,
