On May 1, Nashville will conclude one of the most significant public referendums it has ever held, on the most expensive municipal project the city has ever proposed: a citywide transit overhaul. The initiative, called Let’s Move Nashville, includes upgrades in the bus system and the building of light rail on the city’s major corridors. The plan also includes a tunnel to be dug beneath downtown, from Charlotte Avenue to SoBro. Part of the plan to pay for Let’s Move Nashville is four tax increases: sales, hotel-occupancy, business and rental-car taxes. In this week’s issue of the Scene, staffers Steven Hale and Stephen Elliott highlight the cases for and against passage of the transit initiative. Also in the cover package, Stephen Elliott runs through some of the primaries on the ballot, among them the offices of sheriff, public defender, register of deeds and county clerk. Today on the Scenecast, Hale and Elliott join me to talk transit.
