In November 2011, the Louisville-Southern Indiana Ohio River Bridges Project published a 595-page document that was supposed to finally end a decades-long battle over a highway. The project was a controversial one, to say the least.

At a time when many cities around the country were re-evaluating whether urban highways had a place in their downtowns, Louisville was doubling down. It not only wanted to keep the infamous “Spaghetti junction” where Interstates 64, 65, and 71 meet in a tangled interchange, but it wanted to build more on top of it. In addition, the political alliance behind the project aimed to expand the I-64 crossing to double the lane capacity, as well as build a whole new bridge just down the river—doubling the number of lanes that crossed the river from six to 12—all for a tidy $2.5 billion.
