Try Out the New System Map The RTA operates 32 bus lines and 3 streetcar lines that cover the entire city of New Orleans. Even our customers who ride the RTA every day probably don’t know the full extent of the system. Where do all these lines begin and end? What are their names and numbers? Where can you transfer from one to another? Just use our new System Map to find out. Our new online tool will let you check off as many or as few lines that you wish to see at a time. Everything is color-coded for easy viewing. Then, click on the name on any one of the bus or streetcar lines to display a detailed timetable. Even if you have nowhere to go right now, we invite you to play around with the new System Map here. And once you’re done, remember you can sign up for a My RTA account to save your System Map preferences.
