Hercules is a city in western Contra Costa County, California. Situated along the coast of San Pablo Bay, it is located in the eastern region of the San Francisco Bay Area, about 10 miles (16 km) north of Berkeley, California. As of the 2020 census, its population was 26,016, according to the United States Census Bureau. The site of Hercules was first developed in 1881 as a manufacturing facility of the California Powder Works for the production of its patented dynamite formulation, Hercules powder. In 1882, the Hercules Powder Company was incorporated and assumed responsibility for the Hercules site. It was one of several explosive manufacturers that were active along the Pinole shoreline in the late 19th to the mid-20th century. The small company town that grew up near the facility subsequently became known as "Hercules", and was incorporated at the end of 1900. Starting in the 1970s, Hercules was heavily redeveloped as suburban bedroom community that lies along the I-80 corridor in Western Contra Costa County. It has a very ethnically diverse population.

Rodeo (; Spanish for "Cattle roundup") is a census-designated place (CDP) located in Contra Costa County, California, in the East Bay sub-region of the San Francisco Bay Area, on the eastern shore of San Pablo Bay, 25 miles northeast of San Francisco. The population was 9,653 at the 2020 census. The town is named for the rodeos common in the late 19th century. Cattle from the surrounding hills were regularly driven down through the old town to a loading dock on the shoreline of San Pablo Bay for shipment to slaughterhouses, a practice which continued through the early 20th century. The town of Rodeo is served by the Interstate 80 freeway and State Route 4. The Southern Pacific Railroad main line passes through Rodeo. Rodeo has not been a stop on the railroad since the 1950s.

Hercules Transit Center is a major commuter hub in the western Contra Costa County city of Hercules, California. It is anchored by WestCAT bus services. The center was originally on San Pablo Avenue. In August 2009, the transit center was relocated to the other side of I-80 with additional paid parking. The transit center is a pulse (a timed and synchronized) transfer point for various local feeder bus lines from the adjacent areas of Hercules, Pinole, Rodeo, the northern Hilltop area of Richmond, Bayview-Montalvin, and Tara Hills. The feeder services feed express commuter bus service to El Cerrito del Norte BART station in El Cerrito, downtown Martinez (the county seat) and Martinez Amtrak station. These services provide transfers to AC Transit at Richmond Parkway Transit Center, shopping areas at Hilltop Mall Shopping Center and Pinole Vista Shopping Center and transbay service to the San Francisco Transbay Terminal. The westbound weekday morning commute from this point south towards the San Francisco–Oakland Bay Bridge is the most congested in the San Francisco Bay Area since 2001 according to Caltrans. Studies have been concluded as to the feasibility of running BART service to the Transit Center.
