Uh, decades before they needed repairs? In most of these cases the bridges and roads were NOT maintained due to government budget cutbacks and what's more, the roads and bridges were overused compared to their intended capacities, which causes extensive wear.
The Interstate highway system was built between 40 and 55 years ago. There are stretches in California where they look as pristine as when they were built (I-280 between SF and San Jose), and those that look like they're about to crumble (I-580 between Oakland and Hayward). The difference is overuse. I-580 has more than double the intended traffic. I-280 has about
30% of its intended traffic.I'm not sure where you're talking about, but if this is true, it's likely because of the "tax revolts" of the 1970s when California unfortunately passed Proposition 13 and effectively killed off local government's ability to fix anything.
But if you insist that private industry could do a better job, remember that (1) the job goes to the lowest bidder by law in most cases, and (2) private business has to build in a profit margin, making the cost of any project higher by anything from 15% to 50% than what government can do for the same price.
