Arizona State Route 67

State highway in Arizona, United States
The northern segment of the highway is maintained by ADOT, who is responsible for maintaining SR 67 like all other highways around the state. As part of this job, ADOT periodically surveys traffic along its routes. These surveys are most often presented in the form of average annual daily traffic, which is the number of vehicles who use the route on any average day during the year. In 2009, ADOT calculated that around 1,100 vehicles used the route daily at its northern terminus in Jacob Lake. The Federal Highway Administration (FHWA) lists the highway as a National Scenic Byway, and the National Forest Service has also designated it a National Forest Service Byway. a system of roads in the United States important to the nation's economy, defense, and mobility. Due to the closure of park facilities on the north rim of the Grand Canyon during winter, winter maintenance is not undertaken after December 1, with the result that SR 67 is usually closed to vehicular traffic from December 1 until spring.

SR 67 existed as a route to reach the north rim of the Grand Canyon National Park as early as 1927 as a dirt road. By 1935, the road had been improved to a gravel road, and by 1938 it had been paved. In 1941, the road was designated as a state highway and signed as SR 67. In 1985, the highway received the designation of Kaibab Plateau – North Rim Parkway as an Arizona State Scenic Byway. The designation included SR 67 in its entirety as well as extending south into Grand Canyon National Park. Two years later, ADOT obtained the right of way for improvement of the highway from its northern terminus approximately 10 mile (16 km) south. In 1989, an additional right of way was acquired by ADOT from its southern terminus approximately 5 mile (8 km) north. By June of that year, the parkway received the designation of a National Forest Scenic Byway, and in June 1998, the Kaibab Plateau – North Rim Parkway received another designation, this time as a National Scenic Byway. Since establishment, the route has not been realigned and retains its original routing.
