The interchange with I-80 was opened in 1963. The highway was then opened in the period 1974-1980, the northern part involved the widening of the original two-lane road that opened in 1959. The I-505 was originally planned as the I-5W, but suffixed Interstates were later avoided as much as possible.

Interstate 780 in California
Interstate 780 or I -780 is an Interstate Highway in the US state of California. The highway provides a short connection between Interstate 80 in Vallejo and Interstate 680 in Benicia, both located in the San Francisco Bay Area metropolitan area. The highway is 11 kilometers long.
The highway begins at a cloverleaf interchange with I-80 in Vallejo. Vallejo is a somewhat larger suburb with 117,000 inhabitants located 50 kilometers from San Francisco and 125 kilometers from San Jose. The highway runs to the southeast and has 2×2 lanes. Vallejo almost immediately turns into Benicia, a town of 27,000 inhabitants. Here, I-780 merges with I-680 toward Concord, Pleasanton, and San Jose.
In the late 1950s, the first fragment of I-780 was opened, in fact no more than an access road to a cloverleaf cloverleaf with Interstate 80 that was then constructed along Vallejo. In 1960, the highway was extended east to Columbus Parkway, and in 1962 the rest of the highway through Benicia opened to traffic, simultaneously with the opening of the Benicia-Martinez Bridge into connecting Interstate 680. In 1973, the highway was designated I- 780 numbered.

San Mateo Bridge

The San Mateo Bridge or the San Mateo-Hayward Bridge is a girder bridge in the United States, located in the San Francisco Bay Area in California.
The San Mateo Bridge is a girder bridge spanning the southern part of the San Francisco Bay between Foster City to the west and Hayward to the east. Over the bridge is State Route 92 in California with 2×3 lanes. The bridge is the longest in the area with a length of 11,265 meters. The maximum free passage under the bridge is 41 meters. The bridge is located about halfway between San Francisco and San Jose and handles mostly regional traffic. State Route 92 is a freeway, connecting the expensive suburbs and work locations in San Mateo County with the more industrial and cheaper Alameda County. The bridge is located 16 miles south of the San Francisco-Oakland Bay Bridge and 8 miles north of theDumbarton Bridge.
The first bridge on this site opened to traffic in 1929 and was a two -lane causeway with a lift bridge for shipping. In the mid-1960s, the bridge was replaced by the current bridge, which had three times the capacity. The bridge opened to traffic in October 1967. The bridge originally had only 2×3 lanes on the main span and 2×2 lanes on the bridge bridges. In 2003, the bridges were widened to 2×3 lanes, solving an important bottleneck. Before that, the bridge was the most traffic-prone evening rush hour in the San Francisco region.
In 2010, 86,000 vehicles drove daily over the San Mateo Bridge, which is therefore not overloaded.
The bridge is a toll road, like all bridges in the San Francisco Bay Area. The toll is also $5 here and is only levied westward.

The San Diego-Coronado Bridge is a girder bridge in the United States, located in San Diego, California.
The bridge spans the San Diego Bay between San Diego and Coronado and is located on a bend. It is a girder bridge with a total length of 3,407 meters and a main span of 573 meters. The maximum free passage under the bridge deck is 61 meters. State Route 75 runs over the bridge with 5 lanes, the middle lane is a reversible lane with a movable barrier. Free passage is quite large, which is because San Diego is an important naval base.
The bridge was constructed between 1967 and 1969 and opened to traffic on August 3, 1969. Construction cost $50 million at the time. It is the only major bridge in the San Diego area. The bridge was originally a toll road with a toll of $0.60 in both directions, which was changed after a few years to $1 in the west only. In 2002, the toll was scrapped and was the last toll bridge in Southern California to become toll-free.
In 2010, 75,000 vehicles crossed the bridge every day.
