State Route 99 is an interesting highway. The northern portion of it provides access to Leupp from I-40, however there is a southern segment that runs from Winslow to the middle of nowhere where it just randomly ends and continues as a county road which eventually reaches the Apache National Forest.
SR 99's end is actually somewhat undefined. Both signage and the state highway system map shows the route ending just south of Thunder Road. However, most maps and many other sources say that the route goes all the way to the Apache-Sitgreaves National Forest border.
