The most recent article posted on the Operations Channel is titled A Bridge to Everywhere and briefly explores some notable facts and figures concerning our nation’s bridges, as part of our ongoing infrastructure series.

LEED V3 Provides New Tools.

Many homeowners are running amok trying to sell their homes in a downturned economy.

Written by

In today’s news there’s talk of a new federal government jobs stimulation program, with a cost between $75 billion and $125 billion. This new jobs program would be funded in theory from recaptured amounts totaling nearly $200 billion, originally programmed under the 2008 Troubled Asset Relief Program (TARP).

Approximately $50 billion of the new jobs program would be targeted for U.S. infrastructure projects, i.e., roads, bridges, and water projects. As’s U.S. infrastructure watchdog, this particular aspect of the news caught my attention Tuesday.
