**Question 1:** Which of the following bridge collapses prompted Congress to mandate the National
Bridge Inspection Program (NBIP)?
A) The I-35W Mississippi River Bridge collapse
B) The Silver Bridge collapse
C) The Tacoma Narrows Bridge collapse
D) The Sunshine Skyway Bridge collapse
**Correct Answer: B**
**Rationale:** The collapse of the Silver Bridge in Point Pleasant, West Virginia, in 1967 was a pivotal
event that led directly to the establishment of the National Bridge Inspection Program (NBIP). The tragedy
exposed significant deficiencies in bridge safety oversight, prompting Congress to enact legislation
requiring regular inspection standards for all bridges on public roads .

**Question 2:** Which type of load is considered a permanent (static) load on a bridge?
A) Vehicular live load
B) Dynamic load allowance
C) Dead load
D) Wind load
**Correct Answer: C**
, **Rationale:** Dead load refers to the static, permanent weight of the bridge structure itself, including all
its components, as well as any immovable attachments like wearing surfaces and utilities. Unlike live
loads (vehicles, pedestrians) or environmental loads (wind, ice), dead loads are constantly present and
do not change over time once the structure is built .

**Question 3:** What is the primary inspection method used for the majority of bridge inspections and
evaluations?
A) Destructive testing
B) Underwater inspection
C) Visual inspection
D) Acoustic tomography
**Correct Answer: C**
**Rationale:** Visual inspection is the foundation of the National Bridge Inspection Program. It is the
primary method used to identify visible defects, deterioration, and damage, and it is sufficient for the
majority of routine bridge evaluations. While advanced methods (like acoustic tomography) may
complement an inspection, visual assessment remains the core practice .
