was still completely unimproved between Crescent City and Waldo, Oregon. (Oregon changed the Grants Pass-Crescent City Highway name to Redwood Highway in May 1924.) A new highway between Gasquet and Kerby was completed by the two states in September 1926, and in June 1929 the new Hiouchi Bridge over the Smith River was dedicated, bypassing the remainder of the old road over Howland Hill. In 1948, US 199 became part of the Winnemucca to the Sea Highway, organized to promote the route that has largely become Nevada State Route 140 and Oregon Route 140 from I-80 at Winnemucca, Nevada to Crescent City. One major improvement to the highway's alignment was made after 1929: the Collier Tunnel replaced the winding route over Hazel View Summit in California on July 20, 1963. Neither of the early designations — Highway 25 and Route 1 – was marked (signs posted by the California State Automobile Association used the Redwood Highway name), but in 1926 it became U.S. Route 199, a branch of US 99 from Grants Pass to US 101 in Crescent City. Oregon moved the Pacific Highway No. 1 from present OR 99 to I-5, which bypassed Grants Pass, in 1959, and the Redwood Highway No. 25 was extended north through downtown Grants Pass to I-5. A proposed branch on M Street to I-5 east of downtown was also included in Highway 25, but this was moved to the E and F Streets one-way pair in 1961. (I-5 here was built in the early 1960s, but US 99 remained on the old alignment.) On the California side of the state line, US 199 was added to the California Freeway and Expressway System in 1959 and the State Scenic Highway System in 1963; in the 1964 renumbering the Route 1 designation was dropped, making Route 199 the legislative number. Although US 299 and US 399 became state routes in 1964, the shorter US 199, which crossed a state line, remained. US 99 has since become Oregon Route 99 through Grants Pass, and US 199 now ends at I-5. The spur east from downtown Grants Pass to I-5 was built at the same time as I-5, and in 1991 it was moved from E and F Streets to bypass downtown on the new Grants Pass Parkway.
