What percentage increase in the number of bridges has occurred over the past 20 years?

The percentage increase in the number of bridges over the past 20 years being 6% reflects a modest yet noteworthy growth in infrastructure. This figure indicates a steady investment in bridge construction and maintenance, which can be crucial for transportation efficiency and safety in the trucking industry.

A 6% increase suggests a balanced approach towards infrastructure development. It highlights ongoing efforts to support the growing demands on transportation networks, especially as freight and passenger traffic increase over time. This level of increase is often seen in contexts where compliance with safety standards, technological advancements, and structural integrity are vital considerations in bridge engineering.

This answer indicates that while there has been some growth, it has not been exponential, reflecting economic, planning, and funding realities that affect construction over extended periods. The other percentages presented do not align with the generally reported statistics for the increase in bridges, which further validates the chosen answer.
