Crumbling Infrastructure: Case Study Report
This is our Case Study Report on the responsible actors surrounding the 35W bridge collapse. The report takes a detailed look at the history of USDOT and the 35W bridge and then investigates the involved parties to help determine who is responsible for the collapse. This paper encourages a methodical process towards discovering what went wrong and why, further pressing on into the policy that is likely to come about in the wake of August 01 2007.

A clairvoyant article from the National Science Foundation on the current glass-like nature of bridges and the bridge building materials of the future. This article seeks to show the limitations of current materials being used to build infrastructure and the possiblilities for the future.
Refractions: Engineering and History
This short essay exemplifies a trend in history for repeating mistakes over and over and further presses the need for us to learn from our past mistakes by looking back on history and using it to prevent making mistakes in the future (What does this say about policy?)

These articles are from an engieering perspective. They are a compiliation of statemens about the bridge collapse and our infrastructure situation. They tackle issues like where our infrastructure falls short to what issues lie ahead. While the titles may seem redundant to news print from the last month, they in fact carry some great new perspectives and information that most mainstream articles left out; including a look at who is to blame based on what may have caused the collapse and the inevitable impacts that go with it.
