The impetus for the vote was a proposal to build a $174 million BRT system in Nashville called The Amp, which would’ve ran on a 7.1 mile route and served rapidly growing neighborhoods across the city. There’s a more detailed summary of the project over at The Tennessean.

Although BRT has been shown to revitalize economies and reduce congestion, opponents of The Amp voiced concerns about the safety of unloading bus passengers along roadways and whether private land would be used to build dedicated bus lanes.

After the vote, Amp opponents revealed that the conservative group Americans for Prosperity, founded with the support of brothers Charles and David Koch, had lobbied in favor of the bus ban.
