SR-39 Huntsville Roundabout
SR-39 Huntsville Roundabout
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, the Utah Department of Transportation (UDOT) is constructing a new roundabout. Project completion is expected by late fall 2025.
During construction, crews will strive to maintain all-way traffic through the intersection. Drivers should expect intermittent turn lane closures, flagging operations and minor travel delays. To help minimize delays on weekends, no traffic restrictions will be in place from 2 p.m. on Fridays through 5 a.m. on Mondays. All travel lanes will also be open during holiday timeframes.
The new roundabout will feature 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 will be built to accommodate larger recreational traffic and trailers that travel frequently through the area.
The project will make history as the first roundabout constructed on a state road by UDOT’s Region One, which includes the six counties north of Salt Lake City.

Ogden Valley pedestrians and cyclists are advised that the Pineview Loop Path is closed on the northwest corner of the Main Street (100 South) and SR-39 intersection in Huntsville.
