By: Amy Nguyen and Heather Hernandez

Basic Information

• Location: In San Francisco, California

• What it is: A Suspension Bridge connecting San Francisco to Marin county

• Made of: Steel

• Who built it: There were 10 main people who worked on the construction of the Golden Gate

Purpose of the Golden Gate Bridge

• The purpose of the Golden Gate Bridge is to connect San Francisco Peninsula to Marin County.

• Before they built the Golden Gate Bridge, anytime a person who would want to cross the San Francisco bay, they would have to take a ferry.

Designing and Building

• The Architects that built the Golden Gate Bridge were Joseph Strauss, Charles Alton Ellis, and Irving Morrow.

• Joseph Strauss was the original designer of the bridge. The construction started in 1933 and opened in 1937.

• The Dimensions are 8,980 feet long, 220 feet above the water’s surface, and 746 feet tall.

This picture was the original design:

• The bridge took 12 years to design.

• They design it in 1921 and finished designing in

1930

Cost of the Golden Gate Bridge

• It cost $35 million to build plus interest.

• It would cost $1.2 billion in 2003 dollars.

• It now costs $7, $6, or $4 to cross the bridge.

• Their estimated cost was $25 to $35 million to build the bridge initially.

Unique Features

• It was the longest suspension bridge until the Verrazano-Narrows bridge opened in 1964.

• Ten men died during the construction.• On April 2011, 1,929,896,448 cars have traveled across.

• Night view of the Golden Gate Bridge looks very bright and beautiful.

Our Opinion

• We think the Golden Gate Bridge was designed and made efficiently.

• The bridge itself looks very attractive. It’s features and qualities attract tourists.

• We wouldn’t have changed the design because we think it is already good.

Structural Engineer

• A structural engineer designs structures such as buildings, bridges, and roadways. They also make blueprints and find possible failures, damages, or defects in a design.

• To be a structural engineer you need a B.E NG and B.Sc.

• The skills needed are reading, math, problem solving, time management, science, writing, etc. For a bachelor’s degree, you will need 4-5 years of education.

• Their salary can be anywhere from 41k-63k a year. On a day-day basis they would design structures on a computer or see how the construction of their design is going.

• They can also get a more advanced degree for their job or they can also be under the supervision of a more experienced engineer.

• Our opinion is that they have a very important job. We however wouldn’t be interested in this profession because there is other jobs that we feel like would be better suited for us.

Cargo Bridge 2 levels 1-5

• Level 1: I built this bridge like this for it to support the person’s weight

• Level 2: I built this bridge so that the bottom joint would

support the top.

• Level 3: I didn’t add support on the bottom

because the ropes are already holding it up

• Level 4: One my 1st bridge, the little hill supported the weight. On the 2nd one, I did the same as level 3.

• Level 5: I used steel to support the fat elephant.

Our bridge Information

• Weighs: 144.0 grams

• Length: 40 cm / 15.5 inches

• Width: 10 cm / 4 inches

• Height: 10.5 cm / 4.25 inches

• Cost Calculation: $16.35

We would want our ratios to be low because if it was an efficient bridge and it was low costing, it would be more convenient for the person buying it.
