The Carquinez Bridge is a pair of parallel bridges spanning the Carquinez Strait at the northeastern end of San Francisco Bay. They form the part of Interstate 80 between Crockett and Vallejo, California, United States. The name Carquinez Bridge originally referred to a single cantilever bridge built in 1927, which was part of the direct route between San Francisco and Sacramento. A second parallel cantilever bridge was completed in 1958 to deal with the increased traffic. Later, seismic problems made the 1927 span unsafe in case of an earthquake, and led to the construction, and 2003 opening, of a replacement: a suspension bridge officially named the Alfred Zampa Memorial Bridge, in memory of iron worker Al Zampa, who played an integral role in the construction of numerous San Francisco Bay Area bridges. The Alfred Zampa Memorial Bridge carries southbound traffic from Vallejo to Crockett, and the 1958 cantilever span carries northbound traffic.

The Carquinez Strait (; Spanish: Estrecho de Carquinez) is a narrow tidal strait located in the Bay Area of Northern California, United States. It is part of the tidal estuary of the Sacramento and the San Joaquin rivers as they drain into the San Francisco Bay. The strait is eight miles (13 km) long and connects Suisun Bay, which receives the waters of the combined rivers, with San Pablo Bay, a northern extension of the San Francisco Bay. The strait formed in prehistoric times, near the close of one of the past ice ages, when the Central Valley was a vast inland lake. Melting ice from the Sierra Nevada raised the water level while seismic activity created a new outlet to the Pacific Ocean, draining the lake into the ocean and exposing the valley floors.

Carquinez Strait Lighthouse is a lighthouse in California, United States. It was originally approximately 20 miles inland from the mouth of the San Francisco Bay near Vallejo, California.

Carquinez Strait Powerline Crossing was the world's first powerline crossing of a large river. It was built in 1901 for a 60 kV powerline operated by Bay Counties Power Company to deliver electric power from their Colgate powerhouse to Oakland, California. For this a crossing of Carquinez Strait was required, which has at its narrowest point at Dillon Point a width of 838 metres (0.52 mi). Such a span width was impossible with wooden poles, which were common in those days. Installing an underwater cable was considered, but for reliability reasons an overhead power line was installed, which used at the north site of the river a 68 metres (223.10 ft) tall lattice tower and at the south site one with a height of 20 metres (66 ft).

Selby is an unincorporated community in Contra Costa County, in the East Bay region of the San Francisco Bay Area in northern California.

The Nustar Fire was a fuel storage fire and wildfire at the NuStar Energy facility in Crockett, California, which started about 2:00 PM on 15 October 2019. By 9:00 PM the same evening, the fire was contained, though two tanks of ethanol were still burning. About 15 acres burned. The ATF and other agencies investigated the cause of the fuel tank explosions. There is some speculation that the event might have been related to a nearby earthquake 15 hours earlier. On 22 October it was reported that the Nustar Fire was provoking opposition to an expansion of the Phillips 66 refinery tank farm adjacent to the NuStar facility, in Rodeo. As of 25 October 2019 (10 days after the fire), two ships delivering imported ethanol were stuck without a place to unload, since the NuStar terminal was the only terminal in the San Francisco area set up to receive ethanol, and was shut down by the state while they investigated the fire. On 27 October, another fire, the Sky Fire, threatened Crockett, burning another 150 acres along Cummings Skyway. Most of the town and the NuStar facility were evacuated. The Sky Fire was extinguished on 28 October. According to the 30-day interim report on the Nustar fire submitted to the Contra Costa Hazardous Materials Programs by Shore Terminals LLC: The updated material released quantity estimate during the October 15, 2019 fire incident is approximately 6,664 total barrels of ethanol from the impacted tanks and approximately 3,846 barrels of renewable diesel and 43 barrels of jet fuel from the impacted piping. As previously reported, the cause of the incident is unknown and is under investigation by Contra Costa County Fire Protection District with support from several agencies, including yours. David LeCount has been at the site much of the time participating. Shore Terminals LLC submits this as an interim report and will update this report monthly until the investigation is complete and a final report can be submitted in accordance with the Contra Costa County Hazardous Materials Incident Notification Policy. A final report from the Contra Costa County Fire Protection District was completed and presented May 21, 2021. It concluded the first tank explosion was probably caused by an electric fault that ignited an ethanol vapor air mixture in the headspace of the tank. Improper grounding was observed as well as a pallet removed from the vapor line PRV after a 2012 incident. The second tank was damaged by debris from the first explosion.
