    31. 31. Conclusions• Transportation system is not great and it’s notgetting better– 25% of roads will be failed in 10 years– 38% of bridges will be structurally deficient• Additional funding required to hold infrastructuretogether• Deferring repairs will cost much more later!
    32. 32. Conclusions• Delays in funding will cost
