March 2, 2015, it was announced that Charlotte Pike will be the third major corridor in Nashville to have BRT Lite service, joining Gallatin Pike and Murfreesboro Pike. 50 Charlotte Pike BRT, which began service on Monday, March 30, 2015, offers limited stops traveling between Music City Central in downtown to the Charlotte Walmart located off River Road. 52 Nolensville Pike BRT Lite In March 2015, preliminary plans began for a BRT Lite route to be on Nolensville Pike to begin in the fall of 2015. Route 52 Nolensville Pike BRT lite, which began service on Sunday, March 27, 2016, operates on Nolensville Pike and offers more frequent service, but with fewer stops. All buses serve Nolensville Pike between Downtown and Harding Place with branches to Hickory Plaza (Route 52A) and Wallace/Ezell (Route 52B). While the other previous BRT Lite corridors (Gallatin Pike, Murfreesboro Pike, and Charlotte Pike) all feature both a local service to supplement their perspective BRT lite lines, the Nolensville Pike corridor only features the 52 Nolensville Pike BRT Lite (which replaces the 12 Nolensville Road route). Music City Circuit The Music City Circuit is a free circulator bus service in downtown Nashville, began March 29, 2010 to replace the 94 Music City Star Downtown Shuttle.

Likewise, the Green Circuit operates 6:30 a.m. to midnight on weekdays and 11:00 a.m. to midnight Saturdays. Beginning in late March 2015, Sunday service of the Blue and Green routes were added with operating hours of 11 a.m. to 11 p.m. Neighborhood Mini Hubs Nashville MTA is working on plans to add two neighborhood transit "mini-hubs" that will provide better transit and pedestrian connectivity through cross-town bus connections, more local transfer points for riders, and a safe and secure waiting area. The new transit mini-hubs will be strategically located in North Nashville and near the Harding/Nolensville Pike intersection in southeast Nashville. Each mini-hub facility is designed to connect transit users to neighborhoods, commercial areas, parks, greenways and other recreational facilities, and will include a litany of pedestrian-friendly amenities for those wishing to access the greater MTA transit system. Secure bike racks will give cyclists the option to store their bicycles while riding
