**State Route 84** (**SR 84**) is a [state highway](/source/State_highway) in the [U.S. state](/source/U.S._state) of [California](/source/California) that consists of two unconnected segments, one in the [San Francisco Bay Area](/source/San_Francisco_Bay_Area) and the other primarily in the [Sacramento–San Joaquin River Delta](/source/Sacramento%E2%80%93San_Joaquin_River_Delta) area.

The first section is an east–west [arterial road](/source/Arterial_road) running from [SR 1](/source/California_State_Route_1) in [San Gregorio](/source/San_Gregorio%2C_California) to [Menlo Park](/source/Menlo_Park%2C_California), across the [Dumbarton Bridge](/source/Dumbarton_Bridge_(California)) through [Fremont](/source/Fremont%2C_California) and [Newark](/source/Newark%2C_California) and ending at [I-580](/source/Interstate_580_(California)) in [Livermore](/source/Livermore%2C_California). The segment between Marsh Road and the Dumbarton Bridge has been upgraded to an [expressway](/source/Limited-access_road) and is known as the Bayfront Expressway. The segment from the eastern end of the Dumbarton Bridge to the interchange with I-880 has been upgraded to a freeway.

The other section is a north-south arterial road that begins at [SR 12](/source/California_State_Route_12) in [Rio Vista](/source/Rio_Vista%2C_California), passes through [Ryer Island](/source/Ryer_Island) (where it connects to [SR 220](/source/California_State_Route_220)), and ends in [West Sacramento](/source/West_Sacramento%2C_California). The [Ryer Island Ferry](/source/Ryer_Island_Ferry) provides the crossing over Cache Slough from Rio Vista to Ryer Island. The ferry is a diesel-powered boat operated by [Caltrans](/source/Caltrans), and is in operation twenty-four hours per day and charges no toll.

There are no plans to connect the two unconnected segments of SR 84 at this time. A proposed toll road called the **Mid-State Tollway** along the proposed route was abandoned in 2001 due to local opposition.

## Route description

### Southern section

The route begins at [SR 1](/source/California_State_Route_1) on the [Pacific](/source/Pacific) coast near [San Gregorio](/source/San_Gregorio%2C_California). It then heads northeast through [San Mateo County](/source/San_Mateo_County%2C_California), following San Gregorio Road and La Honda Road and crossing the [Santa Cruz Mountains](/source/Santa_Cruz_Mountains). As it enters [Woodside](/source/Woodside%2C_California), it intersects [SR 35](/source/California_State_Route_35), also known as Skyline Boulevard. From the juncture of La Honda Road with Portola Road to US 101 it follows Woodside Road. It then passes through downtown Woodside. After intersecting [I-280](/source/Interstate_280_(California)), it enters [Redwood City](/source/Redwood_City%2C_California), where it intersects [SR 82](/source/California_State_Route_82), which carries [El Camino Real](/source/El_Camino_Real_(California)) through the South Bay. A few miles later, it interchanges with [US 101](/source/U.S._Route_101_in_California), which it overlaps for a few miles.

Upon routing eastward, it enters the city of [Menlo Park](/source/Menlo_Park%2C_California) as an [expressway](/source/Limited-access_road), called the **Bayfront Expressway**, which features traffic signals at Menlo Park streets, at [driveways](/source/Driveway) serving [Meta](/source/Meta_Platforms) headquarters, and at intersections with [SR 114](/source/California_State_Route_114) and [SR 109](/source/California_State_Route_109). The Marsh Road intersection, in 2013, was the site where a car struck cyclist Sam Felder, a Facebook employee, after he ran a red light. He died 3 months later.[3] The SR 114 (Willow Road) intersection was the site of a car crash in which author [David Halberstam](/source/David_Halberstam) was killed on April 23, 2007.[4]

SR 84 then becomes a freeway at the south end of San Mateo County as it crosses as the [Dumbarton Bridge](/source/Dumbarton_Bridge_(California)) over the [San Francisco Bay](/source/San_Francisco_Bay). Midway over the bridge, it enters [Alameda County](/source/Alameda_County%2C_California). In [Alameda County](/source/Alameda_County%2C_California), it runs northward through the city of [Newark](/source/Newark%2C_California), where it begins a concurrency southwards with [I-880](/source/Interstate_880_(California)) for about one mile. Both interchanges with I-880 are [partial cloverleaf interchanges](/source/Partial_cloverleaf_interchange). Upon separation, however, the route is not built to freeway standards as it enters the city of [Fremont](/source/Fremont%2C_California), following the streets of Thornton Avenue, Fremont Boulevard, Peralta Boulevard, and Mowry Avenue, which after, it has a short concurrency northwards with [SR 238](/source/California_State_Route_238).

SR 84 then leaves Fremont through the historic [Sunol Valley](/source/Sunol_Valley). Parts of the valley are extremely narrow and are referred to as [Niles Canyon](/source/Niles_Canyon); this part of the route is officially a [scenic route](/source/Scenic_route).[5] The section is known as **Niles Canyon Road**, and there are legends of a [Niles Canyon ghost](/source/Niles_Canyon_ghost) inhabiting the area.[6]

After exiting the valley, it begins an overlap with [I-680](/source/Interstate_680_(California)). After separating, it runs through Vallecitos Valley. It then goes over grasslands until it reaches a pass, then enters the city of [Livermore](/source/Livermore%2C_California) with Ruby Hill development on the left. SR 84 then runs along Isabel Avenue until it meets [I-580](/source/Interstate_580_(California)), as the end of its southern section. SR 84 is unconstructed from I-580 to [SR 12](/source/California_State_Route_12).

### Northern section

Ryer Island ferry

The second section of SR 84 starts in [Rio Vista](/source/Rio_Vista%2C_California) at SR 12. It then follows the [Ryer Island Ferry](/source/Ryer_Island_Ferry), which carries the route across the [Cache Slough](https://en.wikipedia.org/w/index.php?title=Cache_Slough&action=edit&redlink=1). When it leaves the ferry, it intersects [SR 220](/source/California_State_Route_220). It continues northward and meets the end of state maintenance at the [West Sacramento](/source/West_Sacramento) city limit, about six miles east of an intersection with [CR E19](/source/County_Route_E19_(California)). It then enters the city of [West Sacramento](/source/West_Sacramento%2C_California) in [Yolo County](/source/Yolo_County%2C_California). It then interchanges with [I-80 Business](/source/Interstate_80_Business_(Sacramento%2C_California)), also signed as [US 50](/source/U.S._Route_50_in_California). As it continues northward, it ends at [I-80](/source/Interstate_80_in_California). From north of West Sacramento, SR 84 has been relinquished and was given to the city of West Sacramento in 2003.[7]

SR 84 is part of the [California Freeway and Expressway System](/source/California_Freeway_and_Expressway_System),[8] and from I-280 to the eastern Fremont city limits and from the southern terminous of Isabel Avenue in Livermore to I-580 is part of the [National Highway System](/source/National_Highway_System_(United_States)),[9] a network of highways that are considered essential to the country's economy, defense, and mobility by the [Federal Highway Administration](/source/Federal_Highway_Administration).[10] SR 84 is eligible for the [State Scenic Highway System](/source/State_Scenic_Highway_System_(California)),[11] and is designated as a scenic highway by the [California Department of Transportation](/source/California_Department_of_Transportation) from SR 238 to I-680 in Alameda County,[12] meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community.[13]

## History

### Original routing

Until recent years, all of CA-84 consisted of narrow, two-lane roads in California. This has remained almost unchanged except for urban areas and the CA-84 widening project in the Tri-Valley.

### Modern history

#### Mid-State Tollway

Route 84 is legally defined to continue from I-580 to [SR 4](/source/California_State_Route_4) in [Antioch](/source/Antioch%2C_California), but there are currently no plans in place to bridge the gap at this time. A plan to build a $600 million [toll road](/source/Toll_road) called the **Mid-State Tollway** along the proposed route was suspended in 2001 due to local opposition.[14]

#### CA-84 widening project

In the late 2000s and 2010s, a widening project began on Route 84 from I-680 near Sunol to I-580 in Livermore. This included a better connection between Stanley Boulevard and Isabel Avenue.[15] The project was to be done in five phases:

1. Isabel Avenue/I-580 interchange

1. Jack London Boulevard to Concannon Boulevard, including connections to Stanley Boulevard

1. Concannon Boulevard to Vallecitos Road intersection and southern Ruby Hill entrance

1. Northern side of pass

1. Southern side of pass to I-680

Costs were estimated to be between $400 and $500 million.[16]

As of mid 2019, phases 1, 2, 3 and 4 are complete. This still leaves the southern section of CA 84 in its original condition.

#### Ryer Island Ferry

Both the Ryer Island Ferry and the [Howard Landing Ferry](/source/Howard_Landing_Ferry) along [Route 220](/source/California_State_Route_220) are the only state-run ferries, and there are no plans to replace them with bridges due to the low traffic numbers around Ryer Island.[17][18][19] The only road bridge connecting Ryer Island is on its north side, which results in longer commutes for residents if one or both ferries shutdown.[20]

## Major intersections

Except where prefixed with a letter, [postmiles](/source/California_postmile) were measured on the road as it was in [1964](/source/1964_state_highway_renumbering_(California)), 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 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](/source/California_postmile#Official_postmile_definitions)).[21] 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.
