WASHINGTON (AP) - Of the many items debated in the 2012 presidential campaign, there's not much talk about planes, trains, roads and bridges.
But as Superstorm Sandy reminds the world, we can't afford to do without them. So why isn't the nation's transportation infrastructure a hot topic?
Money, for one.
Neither President Barack Obama nor Mitt Romney has a good idea how to pay for what needs to be done.
Most of the transportation network was built in the last century; in some places, it dates to the 1800s. Aging highways, bridges, trains and buses are frequently in need of repair or replacement, and no longer can handle peak traffic demands. More than 140,000 bridges are structurally deficient or obsolete. The problem only will worsen as the U.S. population grows.
