In 2001, Louisville (KY) transit agency TARC was working to acquire land for a light-rail line down the city's central corridor (basically paralleling the existing I-65 corridor) connecting Downtown, the Airport, the Fairgrounds, the University, Churchill Downs. Basically, a giant chunk of tourist destinations and core business needs.
The project got stomped by NIMBY complaints by Old Louisville residents (neighborhood between Downtown and most of those other destinations; and dumb because that OG suburb was built on the backs of once important trolley lines to/from Downtown), and internecine battles with the Commonwealth legislature and KIPDA the "regional transit oversight authority".
(KIPDA seems to have no real authority other than conservatively shutting down TARC projects because it's too much work to actually collaborate with Southern Indiana and neither state understands the benefits of actually enhancing transit in the region because of a sort of cold war between the two, despite the shared interests in the region. But I'm ranting…)
Anyway, fast forward 15 years after the project was cancelled and the region is losing a battle with Nashville and Indianopolis for major regional business conventions (which is probably the biggest money fight between the cities). Louisville has the conference space and hotel inventory space to stay extremely competitive, _except_ that it's spread out across the central corridor: the Downtown Convention Center is "small", but well appointed and surrounded by hotel space; the Fairgrounds is huge with tons of space, and some more hotels, and relatively convenient to the airport. Getting between the two takes about 15/20 minutes in light traffic. The proposed LRT could probably have done it in about the same with proposed stops, if not faster.
The kicker is, though, that the one convention actually trying to utilize all that space in the same convention, manages to nearly grid lock the entire core corridor for the entirety of the convention. What's a 15/20 minute drive most days becomes an hour and a half crawl.
The foresight was there to build LRT before it was needed. It's just stupid that project was killed for political reasons. Now it's incredibly needed and even tougher to get political traction to actually build it.
