State Route 70 (SR 70) is a

Forest Service Byway that parallels the ex-Western Pacific Railroad's Feather River Route
.

The

Interstate 80 (I-80). The road was renumbered SR 70 in the 1964 state highway renumbering
. Today, portions of SR 70 have been upgraded to a four-lane expressway, and even a freeway in a few locations.

Route description

State Route 70 begins at a partial

State Scenic Highway portion of SR 70 begins at SR 149, which is where SR 70 turns northeast out of the Sacramento Valley and into the mountains. The short SR 191 spurs north to Paradise, while SR 70 crosses the West Branch Feather River on the double-decker West Branch Bridge, with the Feather River Route below. A short four-lane section runs over the bridge towards Jarbo Gap, where the present SR 70 merges with the old road (Dark Canyon Road) that was used before the Feather River was dammed to create Lake Oroville in the 1960s.[3]

The Pulga Bridges over the Feather River Route (lower bridge) and North Fork Feather River

After crossing through Jarbo Gap, SR 70 drops down into the canyon of the

overlap southeast from that point, where the East Branch splits into Indian Creek and Spanish Creek.[3]

The highway heads southeast, partly along the latter creek, past

U.S. 395 at Hallelujah Junction.[3]

The portion of SR 70 west of State Route 89 near Blairsden is also eligible for the State Scenic Highway System,[4] but has not been designated as such by Caltrans.[5] The entire route is part of the California Freeway and Expressway System,[6] though it is mostly two lanes. SR 70 south of SR 149 is part of the National Highway System,[7] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[8] All of SR 70 is designated as the Feather River Scenic Byway, a National Forest Scenic Byway.[9]

History

Trails

Sierra Nevada at a lower elevation than the existing Donner Pass route of the California Trail. This split from the Truckee Route of the California Trail near Reno and roughly followed the present SR 70 to Quincy, but, rather than passing through the Feather River Canyon, it followed Oroville-Quincy Highway along ridges to Bidwell's Bar.[10] A company was incorporated on July 23, 1855, to build the Quincy and Spanish Ranch Wagon Road, which bypassed the older trail from Quincy west to Spanish Ranch and began collecting tolls in November. The Pioneer Wagon Road, another toll road, was built in 1856 and 1857, continuing the improvements southwest to Buckeye (just before the Butte County line). An 1866 law authorized Plumas County to improve the portion from Quincy east to Beckwourth. The county also improved the road east from Beckwourth over the pass as part of the Red Clover Wagon Road, which began at Genesee and was completed in the 1870s.[11]

The

Feather River Canyon. While building the railroad, the Utah Construction Company had created a dirt road through the canyon to assist with construction; citizens created the Plumas County Road Association in 1911 to push for improvements to this roadway and creation of a year-round route between Oroville and Quincy (the existing route over the ridges was closed for at least four months each winter). The first state highway bond issue, passed by the state's voters in 1910, included a Route 30 connecting Oroville with Quincy. Plumas County surveyor Arthur W. Keddie surveyed the Feather River Canyon route for the California Highway Commission in 1913, but the state announced in 1916 that the existing ridge route would be improved. After much debate, the state legislative road committee included the statement that this route would follow the Feather River in the 1919 amendment authorizing a third bond issue;[12] instead of keeping it as Route 30, the Highway Commission changed the designation to an extension of the short Richvale-Oroville (now SR 162) Route 21, which was also part of the first bond issue.[13][14]

Modern route

Westbound through the Arch Rock Tunnel, the westernmost of the three

Construction began on July 1, 1928, with

Route 3 (State Route 99) southeast of Chico, including the present SR 70 between Marysville and Oroville.[16][17] Route 87 from Woodland to Oroville and Route 21 from Oroville to east of Beckwourth Pass became a new State Route 24 in 1934;[18] State Route 24 was extended southwest from Woodland to Oakland by the end of 1937.[19]

Main article: Special routes of U.S. Route 40 § California alternate route

In 1954,

1964 renumbering. Southwest of Marysville, former U.S. 40 Alternate instead became State Route 113, and SR 70 ran south along former State Route 24 (Route 232) to a point north of Sacramento, where the new State Route 99 came in from the northwest and continued south.[26][27] Despite SR 70 always ending at State Route 99, it was once signed along State Route 99 (El Centro Road, Garden Highway, and the Jibboom Street Bridge) to Sacramento.[28]

Modern alignments

When it was originally built, the Feather River Highway northeast from Oroville followed the present Oroville Dam Boulevard (

freeways: north of SR 99 to Berry and Kempton Roads in the early 2010s; south from Marysville to the State Route 65 split in the mid-1950s, extended farther south in the late 1960s and late 2000s; and around downtown Oroville, built in the early 1960s.[32] In 2004, SR 70 was upgraded to a four-lane expressway between Feather River Boulevard north of the Bear River and the Yuba/Sutter county line to the freeway portion south of McGowan Parkway.[33] A freeway interchange was constructed in 2008 at Plumas Lake Boulevard for access to the Plumas Lake development previously served at an uncontrolled intersection with Plumas Arboga Road. The removal of this intersection effectively upgraded the expressway portion to freeway south to the Feather River Boulevard intersection.[34][35][36] In the early 2010s, the last two-lane segment of SR 70 south of Marysville was expanded to a four-lane expressway, with a freeway section bypassing the small town of East Nicolaus to the west. In 2015, the interchange with Feather River Boulevard in Plumas Lake was opened to traffic, eliminating the last signalized intersection between Sacramento (with SR 99) and Marysville.[37]

Future

Between Marysville and Oroville, SR 70 is being widened to a four-lane expressway, with a

center left-turn lane and eight foot wide shoulders on each side.[38] The project is estimated to be complete by 2024 with the portions between SR 162 and East Gridley Road already complete.[39]

Major intersections

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on primarily a south-to-north alignment (especially the freeway segment between State Route 99 and State Route 149), and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see California postmile § Official postmile definitions).[1] 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.
