[6] A five-mile section of SR 305 is the site of a yearly human-powered vehicle (HPV) speed record competition conducted by the IHPVA (International Human Powered Vehicle Association),[7] with the record set to 89.59 mph (144.18 km/h) on September 17, 2016.
During repaving in 2009, special attention was paid to the five mile stretch to make sure it was the flattest and smoothest road in the world.

In this process, the Austin – Battle Mountain Road segment of SR 8A was reassigned to a new State Route 305.
