The collapse of an Interstate 5 bridge in Washington state Thursday night offered a wake-up call about the sorry state of disrepair in which we’ve left our country's auto-centric transportation system. But all the talk about aging bridges and infrastructure drowns out a few larger questions -- about how we plan to fund the massive road system we've built, and why, with existing roads crumbling, we keep dropping money on more.
The bridge that collapsed in Washington was built, like many major bridges in the U.S., during the rise of the interstate highway system, circa 1955. That means it had already exceeded by several years the 50-year lifespan typical of American bridges.
Ironically, the bridge in Washington, unlike nearly 70,000 bridges across the country, wasn’t rated “structurally deficient.” It had been inspected as recently as November 2012. But after a half a century, a bridge is likely to need major upgrades of some kind, and with the average bridge in this country now 43 years old, we’re looking at a huge roster of bridges due for repairs. According to the Federal Highway Administration, as of 2009, the backlog of deficient bridges required $70.9 billion to address -- and that number has likely increased since then.
So what are states doing to tackle the problem? They're funneling money to shiny new construction projects instead, natch.
