List of AC Transit routes

A Van Hool bus on Route 72M in Jack London Square, Oakland.

AC Transit is a public transit agency that operates 131 bus lines throughout the East Bay region of California. The agency also administers the Dumbarton Express lines, but operation of those lines was transferred to MV Transportation on December 19, 2011. AC Transit provides extensive local bus service to 17 cities in Alameda and Contra Costa counties and the city of Milpitas in Santa Clara County. Transbay bus service is also provided to San Francisco in San Francisco County, San Mateo in San Mateo County, and Palo Alto and Santa Clara in Santa Clara County.

Route summary

AC Transit bus routes are arranged in seven categories (six numbered, one lettered). Since its inception in 1960, AC Transit has used both numbers and letters to distinguish routes. Many Transbay rail lines were inherited from the Key System and converted to bus routes, and AC Transit continued to use letters to identify the routes. Many Transbay routes continue to follow the original Key System alignments to some degree. The number and letter ranges listed below do not mean that all numbers or letters within a range are in use.

Numbered routes operate within the East Bay:

• 1-99 primarily serve the northwestern part of Contra Costa County and most of Alameda County.
• 200-299 serve the southern part of Alameda County and Milpitas.
• 300-399 serve combined portions of other bus lines, usually only at certain times of day or certain days of the week.
• 600-699 operate primarily on school days only.
• 700-799 are Early Bird Express lines, which are replacing early-morning BART service during a seismic retrofit of the Transbay Tube
• 800-899 are part of the All Nighter network, which provides bus service during owl hours and at times when BART is not operating.

One- and two-digit route numbers are sometimes used as a "base" number for three-digit route numbers. For example, Route 339 is "based" on Route 39.

Lettered routes (A-Z) provide Transbay service (i.e., service across a bridge) between the East Bay and San Francisco, San Mateo, and Santa Clara Counties.

Suffixes (also lettered) are used to distinguish variations in route alignments. Currently, A, B, C, L, M, R, S, and X are used. Some suffixes have specific meanings:

• C denotes Combined service, where portions of two or more routes are combined into a single route. Used on Routes LC and NXC.
• L denotes Limited stop service, where not all local stops are served. Used on Routes 46L and NL.
• R denotes Rapid service, which is limited-stop service with some bus rapid transit characteristics. Used on Route 72R.
• X denotes Express service, where portions of the main route are skipped entirely. Used on Routes NX, NX1, NX2, NX3, NX4, NXC, and OX.

Supplemental numerical suffixes are used to differentiate route variations for lines that already use a lettered suffix. This is the case with the NX lines listed above.

Note: Routes listed below are current as of 19 January 2019. (must be updated for 2020 changes)

Local service

An AC Transit bus operating as Route 70 at the Richmond BART/Amtrak Station.

These routes serve various cities, towns, and attractions in Alameda and Contra Costa counties. One route also serves Milpitas and Santa Clara in Santa Clara County. Several routes provide deviations on select trips, where a bus serves a particular business or school that is not on the regular route.

Historically, Route 51 has been considered the busiest bus route in the East Bay, connecting the cities of Berkeley, Oakland, and Alameda. However, this route was split into Routes 51A and 51B in March 2010.

In early 2015, following several rounds of community meetings, AC Transit announced a proposal for a radical rerouting and redesignation of many lines throughout their service area due to extra funds made available by the passage of Measure BB in November 2014. Called AC Go, the program looks at redesigning bus lines throughout the system to reflect the changing traveling habits of its residents by providing more frequent service on its busiest lines while rerouting others to better serve adjoining communities.

Tempo is the branded bus rapid transit service operated by AC Transit. There is one additional Rapid route.

Route	Route Name	Direction	Terminals		Days of Operation	Cities and Communities Served	Connecting BART Station(s)
			North/East Terminal	South/West Terminal
1T	Tempo	North-south	Uptown Transit Center	San Leandro BART	Daily	Oakland, San Leandro	19th Street/Oakland, 12th Street/Oakland, Fruitvale, San Leandro

These routes provide the following amenities and features:

• Frequent service
• Stop spacing every 1⁄4–1⁄2 mile (0.4–0.8 km)
• Passenger shelters with Tempo or Rapid branding
• Transit Signal Priority (TSP) so buses spend less time waiting at traffic signals

Broadway Shuttle

The Broadway Shuttle, also known as The Free B, is a free shuttle service operating along Broadway in downtown Oakland as part of the Meet Downtown Oakland program. Service is operated by AC Transit under contract with the City of Oakland. Funding is provided by the City of Oakland, Alameda County Transportation Commission, and Bay Area Air Quality Management District with additional sponsorships from Jack London Square, Jack London Improvement District, Downtown Oakland Association, and Lake Merritt-Uptown District Association.

The Broadway Shuttle began in August 2010 and was expanded twice, first in July 2011 and again in December 2014. Late-night Friday and all Saturday service was discontinued in August 2017. The B operates two routes:

Route	Map Color	Terminals		Days and Hours of Operation	Service Frequency
		North Terminal	South Terminal
Day	Orange	Grand & Webster	Webster & Embarcadero	Weekdays, 7 AM - 7 PM	Every 10–15 minutes
Night	Blue	Broadway & 27th Street	Webster & Embarcadero	Weekdays, 7 PM - 10 PM	Every 12 minutes

Special service

Several special service routes, numbered between 300 and 399, cater to various purposes:

• The only currently operating rout combines popular segments of two or more regular routes and operate evenings and/or weekends when ridership is insufficient to support the regular routes.

Route	Direction	Terminals		Days of Operation	Service Notes	Cities and Communities Served	Connecting BART Station(s)
		North/East Terminal	South/West Terminal
376	North-south	Pinole (Pinole Vista Center)	El Cerrito del Norte BART	Daily	Serves portions of Routes 70, 71, 74, and 76. Route provides bi-directional service between Contra Costa College and El Cerrito del Norte BART, then operates as a one-way loop via Pinole and Hilltop Mall.	Pinole, Richmond, San Pablo, North Richmond, El Cerrito	Richmond, El Cerrito del Norte

FLEX service

In 2016, AC Transit started operating two FLEX services that provide on-demand van service to riders in Castro Valley and Newark. These services require passengers to book their trips online, using a smartphone app, or by telephone (up to three months in advance), and vans arrive within 30 minutes after the reservation is made. Customers boarding at a BART station do not need to reserve a trip and can just tell the operator their final destination. Fares are identical to the local fares, and Clipper cards are accepted. These services operate Mondays to Fridays from 6am to 8pm (except holidays).

Route	BART Terminal	Departure Times	Communities Served	Service Notes
Castro Valley	Castro Valley	Hourly at :30 past	Castro Valley	Operated alongside former Route 48, with expanded service to surrounding neighborhoods in northern Castro Valley
North Newark	Union City	Every 30 minutes, at :10 and :40 past	Newark	Operates around the general area of currently suspended Route 275, with additional service to Ardenwood Park & Ride and Newark Senior Center

Early Bird Express

On February 11, 2019, the beginning of BART service on weekdays was changed from 4:00 am to 5:00 am for a three-year period to allow for overnight seismic retrofit work in the Transbay Tube. Thirteen Early Bird Express routes, of which six are operated by AC Transit, were created to provide service between 3:50 am and 5:30 am. The AC Transit-run routes provide Transbay service to the Temporary Transbay Terminal.

Route	Terminals
	Outer terminal	Inner terminal
701	Pittsburg/Bay Point station	Temporary Transbay Terminal
702	Pleasant Hill station	Temporary Transbay Terminal
703	Dublin/Pleasanton station	Temporary Transbay Terminal
706	Bay Fair station	Temporary Transbay Terminal
707	Fremont station	Temporary Transbay Terminal

Transbay service

These routes cross San Francisco Bay and connect the East Bay with San Francisco, San Mateo, and Santa Clara Counties. All routes except Route 800 are lettered. (Route 800 is part of the All Nighter network and is listed in its respective section.) Most Transbay routes operate weekdays only during commute periods; two routes operate throughout the day on weekdays only and three routes operate daily. Most commute-only routes operate westbound from the East Bay in the morning and eastbound to the East Bay in the afternoon, but some service is provided in the reverse commute direction.

Serving San Francisco

All bus routes serving San Francisco cross the San Francisco–Oakland Bay Bridge and terminate at the Salesforce Transit Center (at the third floor).

AC Transit operates one route between the East Bay and Santa Clara County via the Dumbarton Bridge. Additional bus service across the Dumbarton Bridge is provided by Dumbarton Express, which is a Transbay bus service provided under a consortium of five transit operators (AC Transit, BART, SamTrans, Union City Transit, and VTA). Dumbarton Express was operated by AC Transit through December 16, 2011 before being transferred to a contractor.

School service

A series of routes serve a variety of public and private middle, junior high, and high schools in Alameda and Contra Costa Counties. These routes generally operate only when school is in session. While these lines are open to all riders at regular fares, they do not operate during most school breaks and holidays. Some regular local bus routes also provide supplemental school service to nearby schools. These routes are usually timed to match the morning and afternoon bell schedules of all schools served.

There are 46 school routes numbered between 600 and 699: 604, 605, 606, 607, 611, 617, 620, 621, 623, 624, 625, 626, 628, 629, 631, 638, 642, 646, 648, 649, 650, 652, 653, 654, 655, 657, 658, 660, 662, 663, 667, 668, 669, 671, 672, 675, 676, 677, 679, 680, 681, 682, 684, 687, 688, and 696.

All Nighter service

Several transit agencies in the Bay Area, including AC Transit, participate in the All Nighter program. All Nighter buses provide overnight bus service when BART and Caltrain are not operating. AC Transit Route 800 is the backbone of this network, serving eleven or thirteen BART and four Muni Metro stations en route.

All AC Transit All Nighter routes provide timed transfers at Broadway and 14th Street in downtown Oakland. Most routes operate daily including holidays, generally from midnight to 5:00 AM. Weekend morning service on Routes 800 and 801 extends until 6 AM on Saturdays and 8 AM on Sundays, corresponding to the start of BART service for the day.
