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.
Construction Impacts
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.
- A 4-way STOP has been implemented at the intersection.
- When flaggers are not present, drivers must STOP all ways at the intersection before proceeding.
- When flaggers are present, drivers should follow their instructions.
- Please reduce speeds and watch for flaggers and signage.
- 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.
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.
- No detour route is available around the work zone for trail users to access into Huntsville Town.
- To maintain public safety during the closure, trail users are not permitted through the intersection on the roadway as there will be excavation work and heavy equipment in the work zone. Thank you for your cooperation.
