State Route 3 (SR 3) is a state highway in the U.S. state of California. It runs from State Route 36 north along the shore of Trinity Lake, Fort Jones and Etna. The route approaches Yreka, intersecting with Interstate 5, and turns east to Montague. The road was numbered SR 3 in 1964, and most of it has been part of the state highway system since 1933.

Route description[edit]

SR 3 is part of the California Freeway and Expressway System[4] and is eligible for the State Scenic Highway System.[5] Caltrans has subsequently designated it as a scenic highway for its entire length.[6]

State Route 3 begins at the junction with State Route 36 south of the town of Peanut in Trinity County. SR-3 is also known as Bramlot Road from its southern terminus to Hayfork. This stretch of road through the Shasta-Trinity National Forest parallels the Hayfork River. Once SR-3 reaches the town of Hayfork, it travels along Hyampom Road east and snakes through the mountains to Douglas City and the junction with State Route 299. From there, SR 3 runs concurrently with SR 299 north to the town of Weaverville.[7][8]

Trinity Dam in Trinity Lake north of Lewiston

SR 3 then departs from SR 299, providing access to the Whiskeytown-Shasta-Trinity National Recreation Area and Trinity Dam along Lewiston Lake. SR 3 passes through the towns of Covington Mill, Trinity Center, and Wyntoon before paralleling the Trinity River as Weaverville-Scott Mountain Road[7][8] and crossing the Scott Mountains and the Pacific Crest Trail at 5,205 feet (1,586 m) into Siskiyou County.[1]

In Siskiyou County, SR 3 passes through Callahan, Etna, Greenview, and Fort Jones as it turns northeast to intersect with Interstate 5 in Yreka. At this point, State Route 263 continues in the northerly direction towards State Route 96; SR 3 turns east to its northern terminus in the incorporated city of Montague.[7][8]

Junction of SR 3 and A28 in Montague


The short piece from SR 36 north to Peanut was added to the state highway system in 1907 as part of the Peanut Road,[9] which became Route 35 in 1917.[10] Route 35 was extended north from Peanut to Route 20 (SR 299) near Douglas City in 1933, and simultaneously a new Route 82 was created, running from Route 3 (I-5) in the Yreka area southwest to Etna and east to Montague.[11][12] The gap between Douglas City and Etna was filled in 1959 with an extension of Route 82 south to Route 20 near Weaverville; at the same time, the portion between Weaverville and Yreka was added to the California Freeway and Expressway System, which identifies the main routes of transportation in the state of California.[13] The State Route 3 designation was applied to the Peanut-Montague roadway in the 1964 renumbering.[14] The overlap with temporary I-5 (along the portion where SR 3 runs concurrently with Interstate 5 today) near Yreka was removed when the new I-5 bypass was built; the legislative definition was updated to reflect this in 1974, soon after the building of the bypass.[15]

Major intersections[edit]

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see the list of postmile definitions).[3] Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
