State Highway 325, also known as OK-325 or, officially, SH-325, is a state highway in Oklahoma. It is assigned the highest number currently in use for state highways (unsigned Interstate 444 in Tulsa has the highest number of any type of highway in Oklahoma).

OK-325 runs for 38.1 miles (61.3 km)^[1] through Cimarron County, Oklahoma, from the New Mexico border west of Kenton to the traffic circle in Boise City. Along the way it provides access to Black Mesa State Park, near Black Mesa Mountain, the highest point in the state of Oklahoma.

[edit] History

OK-325 was once part of U.S. Route 64. After it was rerouted the number OK-325 was assigned because it used to connect to New Mexico's Highway 325. After New Mexico renumbered its highway system, old NM-325 became NM-456, which OK-325 still connects to.^[2]
