New Sustainable Design Proposed for Collapsed Baltimore Bridge

The original Key Bridge was known for:

• its architectural design

• being the longest bridge

• its historical significance

• being the first suspension bridge

How many construction workers were killed in the collapse?

• 0

• 2

• 4

• 6

What is the main span of the new bridge design suggested by Carlo Ratti Associati?

• 100 meters

• 300 meters

• 700 meters

• 1500 meters

What issue is the National Transportation Safety Board investigating related to the ship Dali?

• The ship's electrical system failure

• A collision with another vessel

• Environmental pollution caused by the ship

• Crew safety violations

What type of bridge design will replace the Francis Scott Key Bridge?

• Suspension bridge

• Arch bridge

• Cable-stayed bridge

• Truss bridge

Why did officials choose the prosed bridge design for the new bridge?

• It is the cheapest option

• It is more resistant to ship collisions and material-efficient

• It is easier to construct than the original steel span design

• It is the most common type of bridge in Maryland

What is important about the main span of the new bridge compared to the previous one?

• It places the supports away from the navigation channel to improve safety

• It has a taller span to allow larger ships to pass safely

• It looks more impressive

• It will include six lanes instead of the original four

How does the new bridge’s design contribute to environmental sustainability?

• It eliminates the need for any concrete

• It uses recycled materials exclusively

• It reduces carbon emissions by using material-efficient construction techniques

• It will be made entirely of wood

Why was the collapse of the old bridge particularly devastating for Baltimore?

• It was the only bridge in the area

• It disrupted major transportation and economic activities

• It was the oldest bridge in Maryland

• It was not insured against accidents

What was a major factor in the collapse of the original bridge?

• An earthquake

• An electrical fault in the ships controls

• Poor maintenance of the bridge

• Navigation error caused by the crew
