The American Road & Transportation Builders Association says a significant funding boost is needed to maintain the nation’s federal airport construction program. The association says there is dramatic growth in passenger and freight air travel anticipated over the next 15 years.

The current aviation reauthorization law, “VISION 100-Century of Aviation Reauthorization Act,” expires Sept. 30. Congress is considering the future of America’s aviation system including the Airport Improvement Program, which funds airport construction projects.

Figures released by the Federal Aviation Administration show expected passenger and freight travel to rise 63% and 105%, respectively, by the year 2020. The FAA “National Plan of Integrated Airport Systems” also found an annual $4.7 billion shortfall between federal AIP needs and current investment levels.

“Like much of the nation’s transportation network, the civil aviation system is facing a dual crisis—demands on the system far exceed available revenues, and existing airport infrastructure capacity is saturated,” ARTBA said in testimony submitted to the House Aviation Subcommittee. “Compounding this situation is the fact that passenger and freight aviation travel is expected to dramatically increase in the coming years. Clearly a comprehensive solution to this challenge must be developed, and expanding airport infrastructure capacity is a major component of that solution.”

ARTBA pointed out that only one new major airport and seven new runways were built at major airports from 1991 to 2002, and increasing construction material costs are eroding the purchasing power of recent AIP investments. The association also voiced support for an increase in passenger facility charges (PFC), which airports are allowed to impose to generate capital funds, but urged PFC revenue be dedicated to aviation infrastructure improvements.

“Upgrading America’s aviation infrastructure is about more than just relieving congestion and improving the efficiency of airline operations. It is about securing America’s place in the global economic marketplace,” ARTBA said.
