The tragic collapse of the I-35W bridge in Minneapolis on August 1, 2007, was a stark reminder for all of us about the importance of our nation's bridges. In the aftermath of the collapse, Minnesota has pushed hard for rapid replacement of the bridge, but has been frustrated by ongoing debate and disputes with the selection process.

The bridge debate and frustration raging in Minnesota is nothing new. Many prominent so-called "signature" or "landmark" bridges have been built in the past 75 years in the United States, and many more are currently being built or are on the drawing boards.

History will judge the ultimate value of a bridge to society. Today's politically charged bridge selection process and society's emphasis on bridge aesthetics may have negative consequences.
