What issue did Miguel Sofia face during his investigation of the bridge's construction?

• Lack of funding

• Restricted access and unwillingness to provide information

• Natural disasters

• Language barriers

Answer explanation

Miguel Sofia faced restricted access and an unwillingness to provide information during his investigation, which hindered his ability to gather necessary data about the bridge's construction.

What was one of the most apparent issues with the Valdivia Drawbridge?

• The bridge was too short

• The bicycle lanes stopped abruptly

• The bridge was too expensive

• The bridge was too narrow

Answer explanation

One of the most apparent issues with the Valdivia Drawbridge was that the bicycle lanes stopped abruptly, creating a safety hazard for cyclists and disrupting the flow of traffic.

What could happen if a drawbridge is installed backward?

• It could improve traffic flow

• It could lead to improper drainage and alignment of hydraulic arms

• It could increase the bridge's lifespan

• It could reduce construction costs

Answer explanation

Installing a drawbridge backward can misalign the hydraulic arms, crucial for operation, and cause drainage issues, compromising functionality and safety.

What financial impact did the mistakes during the construction of the Valdivia drawbridge have?

• Reduced costs significantly

• Exceeded the budget by millions

• Had no impact on the budget

• Saved money on construction

Answer explanation

The construction mistakes of the Valdivia drawbridge led to significant financial overruns, causing the project to exceed its budget by millions, highlighting the costly consequences of errors in large infrastructure projects.

What solution are engineers working on to address some issues with the Valdivia drawbridge?

• Building a new bridge

• Leveling the road surface and correcting the bicycle lane's placement

• Painting the bridge

• Adding more lanes

Answer explanation

Engineers are focusing on leveling the road surface and correcting the bicycle lane's placement to improve safety and functionality of the Valdivia drawbridge, addressing specific issues rather than constructing a new bridge.

What does the Valdivia drawbridge project highlight about modern engineering?
