Project Overview

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.
