1. What is the primary purpose of a bridge inspection?
To assess the safety and structural integrity of the bridge.
Regular inspections help identify potential hazards or deterioration that
could compromise safety.
2. Which of the following is NOT a common type of bridge?
Floating bridge
Floating bridges exist but are uncommon compared to beam, arch, and
suspension types.
3. What is the minimum frequency for routine bridge inspections
according to Caltrans standards?
Every 24 months
Routine inspections generally occur every two years to ensure ongoing
safety.
, 4. Which Caltrans manual governs bridge inspection procedures in
California?
California Bridge Inspection Manual
This manual provides detailed inspection standards and procedures specific
