California Interstate 880
According to Watchtutorials, Interstate 880 or I -880 is an Interstate Highway in the US state of California. The highway forms a north-south route in the San Francisco Bay Area metropolitan area, and is the primary suburban highway on the east shore of the San Francisco Bay. The highway connects 3 of the 4 largest cities in the metropolitan area, namely Oakland, Fremont and San Jose. The highway is also called the Nimitz Freeway and is 74 kilometers long.

The highway begins at a major interchange with Interstate 80 and Interstate 580 in Oakland, the 3rd largest city in the metropolitan area with a population of 415,000. The highway here has 2×3 lanes, and runs through the industrial and port areas of Oakland. Interstate 980 merges into downtown Oakland, after which the highway has 2×5 lanes. The highway then runs through the southern neighborhoods, and close to the suburb of Alameda, which is located on an island. Oakland International Airport is also located here. After Oakland you enter the suburb of San Leandro, which has 81,000 inhabitants. Here are large industrial estates, and one crosses the Interstate 238, which comes from Castro Valley and Livermore. After this, 2×5 lanes are still available. One passes through Hayward, one of the larger suburbs with a population of 155,000. One crosses here with SR-92, which runs to San Mateo on the other side of San Francisco Bay.
After this you pass through Union City, which has 70,000 inhabitants, and has a large business park. Then you pass through Fremont, the 4th city of the agglomeration with 211,000 inhabitants. Here, SR-84 turns toward Menlo Park, across San Francisco Bay. One passes through Newark, an enclave in the city of Fremont. There are 2×4 lanes available here. Between Newark and Milpitas is a 14-mile industrial estate along the highway. Interstate 680 runs parallel to I-880. In Milpitas, the SR-237, which leads to Sunnyvale and Mountain View, crosses through the so-called Silicon Valley. In San Jose, the largest city in the metropolitan area with 930,000 inhabitants, the US 101 crosses that of Los Angeleswalking to San Francisco. I-880 eventually ends at the interchange with I-280 and SR-17.
On July 22, 1949, the first two-mile stretch of highway opened in downtown Oakland. On June 1, 1950, the highway was extended 6 miles south through Oakland. On June 13, 1952, it reached Lewelling Boulevard for five miles and Jackson Street for three miles on June 5, 1953, completing the highway between Oakland and Hayward. On June 11, 1957, the northernmost portion of the highway opened in Oakland to I-80 for 4 miles. On November 14, 1957, it opened 8 miles to the north of Fremont. On November 24, 1958, the last section as far as San Jose opened to traffic, completing the highway in a relatively short time of 9 years. The highway was then also renamed Nimitz Freeway.
According to citypopulationreview.com, the highway was initially numbered State Route 17. It ran much further south to Santa Cruz, but has been shortened to San Jose since 1984, with the northern portion numbered I-880.
Between 2006 and 2014, I-880 in Oakland was upgraded in stages to withstand earthquakes. The cost of this was $463 million.
HOV lanes & widening
In the 1990s, I-880 was broadened largely in Alameda County, from Oakland to southern Fremont. The largest part has been widened from 2×3 to 2×4 lanes with HOV lanes. In 2009, I-880 was widened in southern Alameda County, between SR-262 and the Santa Clara County border. The highway has been widened here from 2×3 to 2×6 lanes with HOV lanes.
In 2004, HOV lanes opened in northern Santa Clara County, between the Alameda County border and SR-237 in Milpitas. On June 22, 2013, HOV lanes further opened between SR-237 and US 101 in San Jose.

California Interstate 980
Interstate 980 or I -980 is an Interstate Highway in the US state of California. The highway provides a short connection throughout the city of Oakland, passing downtown. Oakland is the 3rd largest city in the San Francisco Bay Area metropolitan area. The highway runs from Interstate 580 to Interstate 880. The highway is 3 kilometers long.
The highway begins north of downtown Oakland at a 4-level stack interchange with I-580 and SR-24, which runs to Walnut Creek. The highway has 2×5 lanes, partly with a BART (Bay Area Rapid Transit) line in the median strip. The highway is also partly below ground level, with many exits. Finally, 2×2 lanes continue to I-880.
Construction of I-980 began as early as the 1960s, but was not completed until 1985 with all interchanges. Planning for the highway began as early as 1947, as Route 226. In 1964, it was renumbered as State Route 24, and in 1976, the short highway was added to the Interstate Highway system. In 1981 the road was renumbered as I-980.
The highway has been constructed in phases from north to south. The first section opened in 1969 as an extension of State Route 24. The interchange with I-580 opened to traffic in 1970. In 1973, a short stretch opened at Downtown Oakland, and in 1981 the highway was extended to I-880.
There used to be vague plans for a second bridge link between Oakland and San Francisco, south of the current San Francisco – Oakland Bay Bridge. These plans never became very concrete, probably because of the very high costs, but the route would probably also have been numbered I-980.
