SR 299 is part of the California Freeway and Expressway System, and from US 101 to SR 3 and from SR 139 to the eastern junction with US 395 is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. Three sections of SR 299 are eligible for inclusion in the State Scenic Highway System: from US 101 to SR 96, from SR 3 to I-5, and from SR 89 to SR 139; however, none are officially designated as a scenic highway by the California Department of Transportation. History State Route 299, from the intersection with US 101 all the way to US 395 in Alturas, was U.S. Route 299 from 1934 to 1964. This was a spur of US 99 running East and West from the junction in Redding, now signed as CA 273 at the intersection of Eureka Way and Market St. The actual road has been realigned many times, mainly to make easier grades and curves through the mountains. In many places, especially in Trinity County, the old roadway can be seen beside the new road, and there are even several bridges visible from the current 299 that seemingly connect nothing to nothing nowadays, one of which is an arch bridge from 1923. In 1934, 299 was the original State Route 44.
