Now that all 50 state departments of transportation and the District of Columbia met a June 30th deadline to assign 50 percent of their ARRA funds to a specific highway projects, state DOT leaders agreed that the successful implementation of economic stimulus money indicates the beginning of an economic recovery.

By the end of August, 3,351 transportation projects were under construction nationwide; $9.74 billion was under contract; 7,701 projects-valued at $25 billion-had been authorized for bidding; and 6,902 highways projects-valued at $18 billion-had been authorized, according to the Federal Highway Administration
