High Quality Content by WIKIPEDIA articles! U.S. Route 199 (US 199) is a U.S. highway in the U.S. states of California and Oregon. The highway was established in 1926 as a spur of U.S. Route 99, which has since been replaced by Interstate 5. US 199 stretches 80 miles (130 km) from U.S. Route 101 near Crescent City, California northeast to Interstate 5 in Grants Pass, Oregon. The highway is the northern portion of the Redwood Highway. In Oregon, US 199 is officially known as Redwood Highway No. 25. The majority of the road in California is the Smith River Scenic Byway, a Forest Service Byway. This route is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System. The first roadway, a plank road, from Crescent City was established in May 1858, and before the US 199 designation was applied to the highway, the roadway was designated Highway 25 and Route 1.
