There's no question the recent bridge collapse in Minneapolis was a terrible tragedy. But that event, along with the steam pipe explosion in New York last month, raises a bigger issue. The aging infrastructure in our nation is becoming a widespread problem. Is there an appropriate Wall Street response?

The American Society of Civil Engineers estimates that the U.S. needs to spend $1.6 trillion to fix roads and infrastructure in this country by 2010. The knee-jerk reaction to a report like that, following a tragedy like the one in Minnesota, is to buy the infrastructure powerhouses like Fluor (FLR) and Foster Wheeler (FWLT).
