MDOT installing permanent J - turn in Clarkdale

The Mississippi Department of Transportation (MDOT) recently began work on a permanent J-Turn intersection at the U.S. Highway 45 and State Route 145 median crossover in Clarke County.

 “This J-Turn intersection will improve safety for motorists on Highway 45 and State Route 145,” said Commissioner Tom King, Southern Transportation District. “Turns and cross-traffic will now be more controlled and allow for safer traffic flow.”

 A temporary J-Turn was installed in 2017 to allow MDOT to evaluate the change and its impact on traffic flow. MDOT added other safety enhancements, including updated roadway striping and rumble strips, at this intersection before the J-Turn.

 In 2009, MDOT installed additional stop signs on each side of the roadway entering the intersection and installed flashing beacons over the stop signs. Following these improvements, MDOT then increased the size of the stop signs from 36 inches to 48 inches.

 In June 2017, the traditional stop signs were replaced with illuminated LED stop signs, and divided highway signs were added. The existing stop ahead signs were also replaced with new signage to improve reflectivity.

 The construction of the permanent J-Turn began in March 2018. MDOT estimates the approximately $2 million safety project will be complete in summer 2018.

 “MDOT’s number one priority is safety,” King said. “This J-Turn will make this intersection safer for the traveling public. Employing non-traditional traffic configurations like J-Turns, roundabouts and diverging diamonds allows for safer and often more efficient travel for Mississippi motorists.”

 “As the construction of this intersection continues, please remember to be safe in work zones,” King said. “April is Work Zone Awareness month, and drivers are reminded to pay attention and avoid distractions while traveling through work zones.”
