The Washington Post reports that the $28 billion of federal stimulus money allocated to transit and highways has already funded 2,000 separate projects around the country. And, significantly, intense competition among companies seeking projects is driving down the cost to government. Earlier this year, when infrastructure investment was first debated, there were a number of voices of doom saying that Buy America rules would delay projects and increase costs.  In fact, numerous U.S. firms have been actively bidding for projects, lining up to share in the work.  According to the Post, 2,000 projects have been approved in just 41 days.
