What is the National Highway System (NHS)?
The National Highway System is a network of roads that are critical to the country’s economy, mobility, and defense. It includes major highways, interstates, and key routes that connect cities, ports, airports, and military bases.

Bridges on the NHS
Bridges on the NHS play a vital role in keeping this system functioning. These bridges support high volumes of traffic and are essential for the safe and efficient movement of people and goods.

Why Condition Tracking Matters
Monitoring the condition of NHS bridges helps ensure safety, guides maintenance and repair priorities, and supports long-term planning. Keeping these structures in good condition helps prevent costly failures, supports economic activity, and ensures reliable transportation for everyone.
