On a case-by-case basis this may seem trivial, but the cumulative effect is hundreds of billions of dollars were wasted on projects like this. Those projects were supposed to “stimulate” the economy. However, no lasting jobs were created, and no net business will be generated as a result of any of these kinds of stimulus efforts. If improvements in one place do cause increased overall traffic, it will simply be at the expense of some other business somewhere else. Contrast wasting money on stimulus projects like the above vs. lowering corporate taxes. Which one has a chance of promoting hiring? It sure is not money wasted on projects and this is another reason why Keynesian stimulus is ludicrous.
