2 PERFORMANCE OF BRIDGES the staffs of 10 state transportation agencies that participated in the program and records of the IBRC projects. The first three chapters of the report summarize the committee's conclusions on the extent to which the IBRC projects met the goals of the program, the utility of the technologies, and opportunities to reduce life-cycle costs of bridges.

4 PERFORMANCE OF BRIDGES needs will highlight the value of cost-saving innovations for repairs or for avoiding the need for repairs. A new federal innovation incentive grant program could contribute to advancing highway management practices by providing data on the performance of alternative technologies and through support for highway agency trials of state-of-the-art management systems and evaluation methods.

6 PERFORMANCE OF BRIDGES Other Actions to Encourage Innovation • Professional interchange: The state highway agencies should recognize the essential role of professional interactions for disseminating technical advances, support the establishment of opportunities for technical exchange, and support the participation of their engineers in these activities. • Existing federal highway innovation programs: Congress should continue to provide funding and direction for the existing innovation programs administered by the FHWA Center for Accelerating Innovation.
