The Regional Transit Authority Bus Lines (RTA)

Operated by the New Orleans Regional Transit Authority, city bus lines offer a convenient, affordable way to get around New Orleans. For
$1.25 one-way you can get to most areas of town, including trendy Magazine Street uptown (Bus Route 11). Much of the city's fleet has been replaced by new, bio-diesel buses with large windows that offer scenic views during the ride.

NORTA currently is operating 30 bus routes throughout New Orleans and you can find maps and schedules for them, as well as streetcars, from their site: http://www.norta.com/routes/
