In 2012, three at-grade intersections along US 63—a four-lane expressway in central Missouri—were identified for improvements by a multi-disciplinary team of engineers, technicians, law enforcement officers, and others who were performing Road Safety Assessments (RSA) on the route between Columbia, MO and the Iowa state border. The three intersections to be improved were those with the highest crash severity of the 11 initially studied: at Hinton Road north of Columbia in Boone County, Routes B and P near Clark in Randolph County, and Route M near Atlanta in Macon County. Among the numerous severe-injury crashes at these locations were four fatal collisions that took place prior to the sites being upgraded.
