Verrazano-Narrows Bridge

Akashi-Kaikyo Bridge

The 1.7-mile-long Golden Gate Bridge, an icon of the San Francisco Bay region, connects the city of San Francisco to Marin County, California. At its completion in 1937, the suspension bridge was considered an engineering marvel—the longest main suspension bridge span in the world.

Tacoma Narrows Bridge collapses

At 5:04 p.m. on October 17, 1989, a 7.1-magnitude earthquake struck the Bay Area. The upper deck at pier E9 on the Bay Bridge failed and crashed into the lower deck, also causing the lower deck to fail. It was the rigid structure of the truss bridge on the East Span that made it more susceptible to failure.

The Bay Bridge had lost one section of the upper deck during the quake and was closed for about a month while the California Department of Transportation made repairs.

The 6.9 magnitude Loma Prieta quake hit, causing a portion of the bridge to collapse and after 25 years of work, Caltrans says the bridge is now one of the safest places to be when the big one strikes. “It has been designed to be able to move with the largest earthquake that could happen in 1,500 years,” Ney said.

how much money does the Bay Bridge make every day? The Metropolitan Transportation Commission states that for the San Francisco Bay Bridge, in Fiscal Year 2014–2015: $/b> in toll revenue was collected. [1] If you divide this by 365 days, this gives an average toll revenue of $625 811.04 per day.

A 1.25-mile segment of the two-level Cypress Street Viaduct along the Nimitz Freeway (Interstate 880), just south of the San Francisco-Oakland Bay Bridge, collapsed during the quake, resulting in 42 fatalities when the upper level of the road crashed onto the cars on the lower level.

E-ZPass Maryland holders pay a discounted toll at most state toll facilities. At the Bay Bridge, the E-ZPass rate for a two-axle vehicle is $2.50. The cash toll is $4, and the video toll rate is $6. The E-ZPass transponder is free for Maryland drivers and there is no fee to create or maintain an account.

The idea of turning the Golden Gate Bridge into a double-decker has been around almost since the bridge was opened in 1937. According to the Golden Gate Bridge District, traffic rose dramatically on the span after it opened, from 3.3 million vehicles in 1938 to 28.3 million vehicles by 1967.

The largest span of the original eastern section was a cantilever bridge. During the 1989 Loma Prieta earthquake, a portion of the eastern section’s upper deck collapsed onto the lower deck and the bridge was closed for a month. Demolition of the old east span was completed on September 8, 2018.

The 8-mile long Bay Bridge is older (by a few months) than the Golden Gate Bridge. But the opening was minor compared with the gala opening of the Golden Gate Bridge just a few months later. And so it has been ever since for the San Francisco-Oakland Bay Bridge.

The name has nothing to do with its color While it’s obvious today that the name isn’t related to its color, many tourists assume that it was once gold. In fact, according to the website, “The term Golden Gate refers to the Golden Gate Strait which is the entrance to the San Francisco Bay from the Pacific Ocean.

The world-renowned bridge is named for the Golden Gate Strait, the narrow, turbulent, 300-foot-deep stretch of water below the bridge that links the Pacific Ocean on the west to San Francisco Bay on the east. Fremont used a Greek term to name it: Chrysopylae – in English, Golden Gate.

The 17 mph winds blowing across San Francisco Bay caused the bridge to sway side to side. Fortunately, the bridge deck was designed to move 15 feet vertically and 27 feet from side to side.
