The programs that would meet the bill’s 90-day restriction are, for the most part, an unappealing mix of projects that were either shelved after being fully designed and engineered, and have since become outmoded or irrelevant, or projects with limited scope and ambition. No one’s building a smart electric grid or revamping a water system on 90 days notice.
The best example of a shovel-ready project, and what engineers believe could become the biggest recipient of the transportation-related portion of the bill’s funding, is road resurfacing—important maintenance work, but not a meaningful way to rein in a national infrastructure crisis. “In developing countries, there are roads that are so bad, they create congestion, because drivers are constantly forced to slow down,” says David Levinson, an associate professor in the University of Minnesota’s civil engineering department. “That’s not the case here. If the road’s a little bit rougher, drivers will feel it, but that’s not going to cause you to go any slower. So the economic benefit of those projects is pretty low.”
