Route FF Intersection Improvements in Greene County

Will Route FF or Weaver Road be closed during construction?

Weaver Road will be closed at Route FF for short periods to construct the roundabout. Signed detours will be provided.

Will the roundabouts accommodate large truck movements?

Yes, roundabouts are designed with a truck apron to accommodate large vehicles, such as semi-trucks, school buses, and farm equipment. Additionally, oversized and overweight trucks frequently use the corridor; therefore, additional truck aprons have been included in the design.

Why were roundabouts chosen for this project instead of traffic signals?

The configuration of a roundabout forces traffic to slow down and eliminates right-angle crashes by directing all traffic in the same direction.  At the same time, roundabouts allow for a smooth flow of traffic and eliminate the unnecessary delays experienced at signals.

We have roundabouts throughout our 21-county district that are functioning well and providing the safety and traffic flow benefits we anticipated.  Other high-speed (45 mph or greater) locations include U.S. 60 and Route 43 near Seneca, Route 96 and Route 171 north of Carl Junction, Route 96 and Route 43 near Webb City, U.S. 166 at Downstream Casino, three locations along U.S. 160 in Willard, and Route M at Repmo Drive (Republic High School).  We also have numerous locations on roadways with posted speeds below 55 mph, including urban areas and interstate interchanges.  These roundabouts are designed specifically for each location, with some serving more truck traffic than others; however, they all provide improved safety and traffic flow.

All national studies and data indicate that roundabouts are the safer improvement.  Before-and-after studies based on multiple locations throughout the U.S. show that converting two-way stop-controlled intersections, such as U.S. Route 65 and Truman Road, to a roundabout leads to an 82% reduction in fatal and injury crashes. Our experience with roundabouts in our own district has also shown that to be true. 

Will any property be impacted?

The new construction will require the acquisition of right-of-way and temporary easements from numerous property owners. Please review the exhibits for additional information. A Right of Way representative will contact affected landowners to initiate the acquisition process. For more information on the acquisition process, please see the Pathways of Progress display above.
