This byway is in northwest California near the Oregon border. The byway’s southeast access is in Yreka off I-5. It heads northwest, crosses into Oregon, and ends at the junction with US 199. State of Jefferson follows CA 263, CA 96, and Grayback Road. The roads are two-lane paved roads suitable for all vehicles. The byway is 108 miles long and is generally open year-round but temporary closure is possible during winter.
State of Jefferson has an interesting footnote in history. On Thursday, November 27, 1941, the State of Jefferson “seceded” from California and Oregon to form the 49th state of the Union. Several counties in northern California and southern Oregon proclaimed their independence to protest the lack of good roads and other basic services. Armed miners displaying the State of Jefferson seal stopped traffic at the “border” on US 99 (now CA 263) to distribute the “Proclamation of Independence.” The proclamation declared an intent to “secede each Thursday until further notice.” Movement for secession, however, was stopped abruptly by the attack on Pearl Harbor. Nowadays the byway traveler is free to cross this beautiful territory known as Klamath National Forest.
Much of the byway follows the meandering Klamath River, a National Wild and Scenic River. Anglers may wish to spend some time attempting to catch salmon or trout. The river is also enjoyed by rafting, canoeing, kayaking, and tubing enthusiasts. Several campgrounds are situated along the banks of the river. Among the wildlife inhabiting the area are deer, otters, geese, ducks, and bears. Bald eagles have occasionally been seen riding the wind currents.
