 Project Description

 
​​During the 2020 construction season, ODOT will construct a Restricted Crossing U-Turn (RCUT)
intersection at U.S. 42 and C.R. 75 (Spring Valley Paintersville Road - SVPR) in Greene County. The existing intersection is stop controlled on SVPR with existing overhead flashers and has experienced a high number of crashes related to left turns and crossing movements. After evaluating alternatives and conducting public involvement, ODOT has determined that constructing an RCUT intersection will provide the most effective safety improvement for this intersection.

 What is an RCUT?

 

A Restricted Crossing U-Turn (RCUT) is a non-traditional intersection that can ease traffic movements and enhance safety. In an RCUT, side-street (minor cross street traffic) is prohibited from turning left or traveling straight through the mainline intersection. Instead, motorists on the side street will turn right onto the mainline and do a legal U-turn at a nearby crossover. In addition to allowing for a more efficient movement of traffic, RCUT intersections reduce the total number of conflict points, thereby limiting collision opportunities and, most typically, the severity of such collisions that may occur.

 

 Why Build an RCUT?

 

Also known as J-Turns, RCUT-style crossings are cost-effective measures that reduce the number of vehicle-vehicle conflict points, reduce the number of turning and angle crashes, and simplify driver decisions. In comparison to signalized intersections and interchanges, construction and maintenance of RCUTs are less costly, easier to maintain and provide a more efficient movement of traffic on the mainline route.

In a recent study of the intersection of U.S. 42 and SVPR, ODOT determined that a total of 52 crashes occurred at the intersection from 2007 to 2017. Of which, twenty-nine, or about 56%, resulted in injuries. The study determined that the most prominent trend of crashes involved left turning and angle crashes.
 

Although several short-term improvements were implemented, crashes were still occurring at this intersection. In 2018, twelve additional crashes occurred at the intersection, eight of which resulting in injury. In the most recent high crash rankings, this intersection is ranked #29 among rural intersections and is the highest ranked rural intersection in Greene County on ODOT’s priority list.

As a proven countermeasure, RCUTs have shown to reduce injury crashes by more than 40% and fatal crashes are reduced by 70% compared to traditional intersections. The safety benefit of the RCUT is that the number of conflict points at the intersection are reduced from 32 to 8.

 Frequently Asked Questions

 
Will the intersection accommodate large vehicles?
Yes, the U-turns have been designed to accommodate emergency vehicles, agricultural farm equipment, and semi-truck traffic.
 
Are there other RCUTs in operation?
Yes, this intersection type has been implemented throughout the country. In fact, the Federal Highway Administration (FHWA) added Reduced Left-Turn Conflict Intersections (which included RCUTs) to their limited list of Proven Safety Countermeasures. 
 
What other alternatives did ODOT consider?
During project planning, ODOT determined that a roundabout is not appropriate for this intersection at this time based on the traffic volumes and roadway characteristics. ODOT also determined that simply adding left-turn lanes would not address the left-turn and angle crash trends. In addition, ODOT has demonstrated that a traffic signal would increase crashes at the intersection.
 
Why not just lower the speed limit in this area?
Speed limits are set by Section 4511.21 of the Ohio Revised Code. While the speed can be lowered through an engineering study, studies have shown that raising or lowering the speed limits does not have a significant effect on speed.
 
Will this project impact the intersection of Old 42?
ODOT completed traffic simulation of the project and determined that the operations of the intersection of Old 42 will not be degraded. Also, the project will add a short northbound left-turn lane on U.S. 42 at Old 42.
