Topic: Breaking New Ground with a Displaced Left Turn Intersection and a Rural Roundabout Intersection
Speaker: Mary Hoy, PE, ODOT District 7Traffic Engineer
In 2010, the first Displaced Left Turn (DLT) intersection in Ohio was opened at the intersection of SR 741 and Austin Boulevard. Approximately 50,000 vehicles travel through this intersection every day and nearby development is rapid and continuous. Even with an innovative intersection design, there have been – and continue to be – many challenges associated with the ever-increasing traffic volumes.
In 2014, possibly the first roundabout on the state system with a 55 mph speed limit on all approaches was installed at the intersection of SR 41 and SR 235 in Clark County. Despite a long history of safety improvements, prior efforts had been unsuccessful in addressing severe crashes. This made the intersection a good candidate for a roundabout with their proven ability to effect major reductions in serious injury and fatal crashes.
