How Much Did It Cost to Build a Ballpark on the Golden Gate Bridge? Estimated cost: $37 million dollars plus interest. Between 1933 and 1937, the Golden Gate Bridge in San Francisco was constructed during a four-and-a-half year span. It is the country's second-largest suspension bridge. The main cable of the bridge is 3,500 feet long and weighs 14,000 pounds per square foot. The main pylon is 250 feet high and weighs 21,000 tons.
The Oakland-San Francisco Bay Bridge is the only other cross-bay highway connecting the two cities. It connects Oakland with the northern end of San Francisco. Opened in October 1964, it carries six traffic lanes and provides access to more than 100,000 vehicles daily. It has been named one of the "Seven Wonders of California" by the American Institute of Architects.
Cost estimates at the time of construction ranged from $27.5 million to $57.8 million ($148-$303 million in 2007 dollars). Today, the price of building a new bridge would be considerably more due to increased materials costs and labor rates. The latest estimate is that it will cost $6.4 billion to replace the current bridge which will not be done until 2047.
When the new bridge is completed, it will be the first major addition to the system since the San Francisco-Oakland Bay Bridge was built in 1964.
The Bay Bridge's construction began in July 1933, and it opened for traffic in November 1936, nearly six months before the Golden Gate Bridge was finished and declared operational. The renovation cost $77 million in total, which was paid for using tolls collected on the Oakland side of the bridge. It was the most expensive single project ever undertaken by the Port of Oakland at that time.
When the new span was completed in 1996, it replaced an aging structure that had been built in 1990. The old bridge was also owned by the port but was operated by the California Department of Transportation (Caltrans).
The new Bay Bridge is a suspension bridge that connects the cities of San Francisco and Oakland. It has three main parts: two parallel tubes with outside decks and inner supports, one for vehicle traffic and one for pedestrian and bicycle traffic.
The new bridge is also one of only four double-leaf bascule bridges in the United States. A bascule bridge opens by swinging down onto the lower deck from the upper deck, like a giant pair of scissors. When open, drivers and pedestrians have clear access across both sides of the bay. When closed, the bascules swing up into place like huge doors, blocking off the view of traffic until they are needed.
The new San Francisco-Oakland Bay Bridge will cost more than $7 billion, according to California, and will be an architectural wonder. However, the state saved a lot of money by outsourcing some of the building work. The new eastern span of the Bay Bridge will be designed to compete with its more famous relative, the Golden Gate Bridge. The main difference between the two bridges is that the East Span will be wider.
The new bridge is expected to open to traffic in 2016. It will connect Oakland and Alameda counties over the estuary of the same name. The existing Treasure Island Bridge also carries traffic over this waterway. It connects Oakland and Contra Costa counties together.
The main purpose of the new bridge is to provide a safer alternative for drivers who use the Bay Bridge to go from Oakland to Silicon Valley. Currently, there are more than 450,000 vehicles that cross the bridge each day. This number is expected to increase as more people move to the east side of the bay.
Some say that the new bridge is too expensive and should have been completed during the original design phase of the project. Others argue that it is needed because of the increasing number of cars being driven in California. Either way, it will be a long-lasting reminder of our state's modern history.
