'''State Route 139''' ('''SR 139''') is a [state highway](/source/state_highway) in the [U.S. state](/source/U.S._state) of [California](/source/California). Running from [SR 36](/source/California_State_Route_36) in [Susanville](/source/Susanville%2C_California) north to [Oregon Route 39](/source/Oregon_Route_39) at the [Oregon](/source/Oregon) state line, it forms part of the shortest route between [Reno, Nevada](/source/Reno%2C_Nevada), and [Klamath Falls, Oregon](/source/Klamath_Falls%2C_Oregon). SR 139 cuts through much of [Modoc National Forest](/source/Modoc_National_Forest) and passes near [Antelope Mountain](/source/Antelope_Mountain) and [Tule Lake](/source/Tule_Lake). North of SR 299 near [Canby](/source/Canby%2C_California), SR 139 was built by the [federal government](/source/Federal_government_of_the_United_States) and turned over to the state in about 1940; the remainder was built by a joint highway district of [Lassen](/source/Lassen_County%2C_California) and [Modoc](/source/Modoc_County%2C_California) Counties, completed in 1956, and given to the state in 1959.

==Route description==
[[Image:Modoc-map.png|thumb|left|SR 139 through the [Modoc National Forest](/source/Modoc_National_Forest)]]
State Route 139 begins at [SR 36](/source/California_State_Route_36) in [Susanville](/source/Susanville%2C_California), and heads northeast up [Antelope Mountain](/source/Antelope_Mountain) along the eastern edge of [Susanville Ranch Park](/source/Susanville_Ranch_Park) before turning north and descending into the [Eagle Lake Basin](/source/Eagle_Lake_Basin), passing along the eastern edge of [Eagle Lake](/source/Eagle_Lake_(Lassen_County)) and later the [Said Valley Reservoir](/source/Said_Valley_Reservoir). The highway continues north and northwest through valleys and over hills and through a part of the [Modoc National Forest](/source/Modoc_National_Forest), through the community of [Avila Place](/source/Avila_Place%2C_California), and then enters the east end of the [Big Valley](/source/Big_Valley_(Pit_River)), where it begins to [overlap](/source/overlap_(road)) [SR 299](/source/California_State_Route_299) through [Adin](/source/Adin%2C_California). The combined routes continue northerly through another part of the forest and over [Adin Pass](/source/Adin_Pass) into the [Warm Springs Valley](/source/Warm_Springs_Valley), where SR 139 splits to the northwest near [Canby](/source/Canby%2C_California).<ref name="maps" /><ref name="gmaps" />

SR 139 runs northwest and north over mostly flat terrain through the center of the national forest before turning northwest. The route continues through [Newell](/source/Newell%2C_California) before cutting across the intermittent [Tule Lake](/source/Tule_Lake) as the Lava Beds Highway through the city of [Tulelake](/source/Tulelake%2C_California). During this segment, SR 139 passes directly through the former [Tule Lake Segregation Unit](/source/Tule_Lake_Unit%2C_World_War_II_Valor_in_the_Pacific_National_Monument), used to house Japanese-Americans during WWII. After passing through the former internment camp, SR 139 continues to the [Oregon](/source/Oregon) state line at [Hatfield](/source/Hatfield%2C_California). At an intersection right on the state line, [SR 161](/source/California_State_Route_161) begins to the west, and [Oregon Route 39](/source/Oregon_Route_39) continues northwest towards [Klamath Falls](/source/Klamath_Falls%2C_OR).<ref name=maps>{{cite map|publisher=ACME Maps|title=ACME Mapper 2.0|url=http://mapper.acme.com/?ll=41.19886,-120.94414&z=8&t=M|access-date=January 6, 2012}}</ref><ref name="gmaps">{{Google maps | url = https://maps.google.com/?ll=41.191056,-120.036621&spn=1.831155,4.284668&t=m&z=8&vpsrc=6 | title = SR 139 | access-date = January 11, 2012}}</ref>

==History==
In 1925, a state-created "California Highway Advisory Committee" recommended a number of additions to the state highway system; among these was a route from [Susanville](/source/Susanville%2C_California) to the [Oregon](/source/Oregon) state line towards [Klamath Falls](/source/Klamath_Falls%2C_OR), via [Bieber](/source/Bieber%2C_California). This would be part of a road connecting [Reno, Nevada](/source/Reno%2C_Nevada) and Klamath Falls east of the [Sierra Nevada](/source/Sierra_Nevada), which would attract heavy traffic and improve access to [Crater Lake](/source/Crater_Lake_National_Park) and [Lassen Volcanic](/source/Lassen_Volcanic_National_Park) [National Park](/source/National_Park_Service)s.<ref name=1925report>California Highway Advisory Committee and Arthur Hastings Breed, Report of a Study of the State Highway System of California, California State Printing Office, 1925, p. 98</ref> A local [county road](/source/county_road) already followed this path, but it was an [unpaved road](/source/unpaved_road), mostly [dirt](/source/dirt_road) and [gravel](/source/gravel_road) but with sections of rock and bad sand. This was close to the present SR 139, with notable deviations around the areas of [Hayden Hill](/source/Hayden_Hill%2C_California), Bieber and [Lookout](/source/Lookout%2C_California), and [Malin, Oregon](/source/Malin%2C_Oregon) (as [Tule Lake](/source/Tule_Lake) covered SR 139's current location).<ref>{{cite book|title=Official Automobile Blue Book Volume Eight|url=https://books.google.com/books?id=Mt0NAAAAYAAJ|pages=266–268|year=1918}}</ref>

By the mid-1920s, the main road southeast from Klamath Falls, still unimproved in California, headed southeast to [State Highway Route 28](/source/Legislative_Route_28_(California_pre-1964)) (now [SR 299](/source/California_State_Route_299)) at [Canby](/source/Canby%2C_California) rather than south to Bieber. There travelers could head east on Route 28 to [Alturas](/source/Alturas%2C_California) and south on the present [US 395](/source/U.S._Route_395_in_California) (not a state highway north of Susanville until 1933) towards Reno.<ref>[Clason Map Company](/source/Clason_Map_Company), [https://web.archive.org/web/20200916015429/http://usautotrails.com/CaliforniaPage/ClasonsCaliforniaPage/image1.html Touring Atlas of the United States], 1925</ref><ref>[Rand McNally & Company](/source/Rand_McNally_%26_Company), [http://www.broermapsonline.org/members/NorthAmerica/UnitedStates/Southwest/California/unitedstates1926ra_072.html Auto Road Atlas] {{Webarchive|url=https://web.archive.org/web/20120212125333/http://www.broermapsonline.org/members/NorthAmerica/UnitedStates/Southwest/California/unitedstates1926ra_072.html |date=February 12, 2012 }}, 1926</ref> The California state legislature passed a law in 1939, providing for state takeover of the Canby-Oregon road if the [U.S. Forest Service](/source/U.S._Forest_Service) and [Bureau of Public Roads](/source/Bureau_of_Public_Roads) were to construct and pave it.<ref>{{cite CAstat|year=1939|ch=338|p=1677}}</ref> The road was in fact mostly paved by mid-1939,<ref>[Nevada State Journal](/source/Nevada_State_Journal), June 30, 1939: "A one-mile stretch at the Modoc-Siskiyou county line is gravel surfaced and from Tule Lake to the Oregon state line the oiled surface is broken and somewhat rough."</ref> and under construction or completed by mid-1940, when [Oregon Route 58](/source/Oregon_Route_58) opened, continuing the corridor northwest from Klamath Falls.<ref>[Reno Evening Gazette](/source/Reno_Evening_Gazette), August 2, 1940: "With the opening of the new Willamette highway in Oregon, connecting U.

The balance of this route is entirely paved and in excellent condition."</ref> In 1943 the legislature gave it the Route 210 designation;<ref>{{cite CAstat|year=1943|ch=964|p=2849}}: "Route 210 is from Route 28 near Canby to the Oregon line near Merrill."</ref> Oregon had added the short connecting [Hatfield Highway](/source/Hatfield_Highway) to its state highway system in 1937.<ref name=HSHO>[Oregon Department of Transportation](/source/Oregon_Department_of_Transportation), [https://www.oregon.gov/odot/ETA/Documents_Geometronics/ROW-Eng_State-Highway-History.pdf History of State Highways in Oregon], January 2007, p. 677</ref>

[Lassen](/source/Lassen_County%2C_California) and [Modoc](/source/Modoc_County%2C_California) Counties organized Joint Highway District No. 14 on December 21, 1929 to construct and maintain a road from Susanville via [Adin](/source/Adin%2C_California) to Oregon. However, since the state took over the part north of Adin, the district's scope was narrowed to Susanville-Adin.<ref>[Division of Highways](/source/Division_of_Highways_(California)), Sixth Annual Report to the Governor on the Activities of the Division of Highways for the Year July 1, 1951 to June 30, 1952, p. 124</ref> It finally completed work in 1956, and held a ceremony on August 26, in which it placed a monument at a point near [Eagle Lake](/source/Eagle_Lake_(Lassen_County)).<!--I can't determine where - it says "Colley Point" but that's not on USGS topos; it says it provides a scenic view of the lake and is about 22 mi north of Susanville--><ref>[Reno Evening Gazette](/source/Reno_Evening_Gazette), Lassen Highway Dedication Held, September 4, 1956</ref> The legislature added the road to the state highway system as Route 216 in 1959.<ref>{{cite CAstat|year=1959|ch=1853|p=4409}}: "Route 216 is from Route 20 north of Susanville to Route 28 near Adin."</ref> The portion south of Horse Lake Road became an extension of [Route 20](/source/Legislative_Route_20_(California_pre-1964)) instead;<ref>{{cite CAstat|year=1959|ch=1062|p=3116}}: "Route 20 is from:...(c) Route 29 near Susanville to Route 73 near Ravendale."</ref> this route from Susanville to [Ravendale](/source/Ravendale%2C_California) (later [Termo](/source/Termo%2C_California)) was never constructed by the state, and was deleted from [SR 36](/source/California_State_Route_36) in 1998. Also in 1959, a spur of Route 210 west to [Dorris](/source/Dorris%2C_California) was added; this became [SR 161](/source/California_State_Route_161) in 1964.<ref>{{cite CAstat|year=1959|ch=1062|p=3118}}: "Route 210 is from: (a) Route 28 near Canby to the Oregon line near Hatfield. (b) A point on the highway specified in subdivision (a) of this section near Hatfield to Route 72 near Dorris."</ref>

By 1946, the Canby-Oregon portion had been marked as Sign Route 139, connecting with [Oregon Route 39](/source/Oregon_Route_39);<ref>[Rand McNally & Company](/source/Rand_McNally_%26_Company), [http://www.broermapsonline.org/members/NorthAmerica/UnitedStates/Southwest/randmcnally_ra_1946_018.html Road Atlas] {{Webarchive|url=https://web.archive.org/web/20120212125342/http://www.broermapsonline.org/members/NorthAmerica/UnitedStates/Southwest/randmcnally_ra_1946_018.html |date=February 12, 2012 }}, 1946</ref> it was extended south over [US 299](/source/U.S._Route_299_in_California) to Adin and Routes 216 and 20 to Susanville by 1960.<ref>[Oakland Tribune](/source/Oakland_Tribune), May 31, 1960: "Nichols was killed when his car missed a turn yesterday morning and overturned on State Highway 139, two miles north of Susanville."</ref> The number was legislatively adopted, replacing Routes 210 and 216, in the [1964 renumbering](/source/1964_renumbering_(California)).<ref name=law-renumbering>{{cite CAstat|year=1963|ch=385|p=1182}}: "Route 139 is from: (a) Route 36 near Susanville to Route 299 near Adin.
