What is the name of the avenue that features the oldest continuously operating street railroad line in the world?

St. Charles Avenue is renowned for hosting the oldest continuously operating street railroad line in the world, known as the St. Charles Streetcar line. This historic streetcar line began service in 1835 and has remained in operation, offering both residents and visitors a scenic ride along one of New Orleans' most beautiful avenues, which is lined with grand oak trees and historic mansions. The line plays a crucial role in the city's transit system and has become an iconic part of the New Orleans experience, showcasing the city's unique combination of history, culture, and transportation innovation.

In contrast, Canal Street is a major commercial district known for its shopping and restaurants, but it does not have the same historical significance in terms of streetcars. Bourbon Street is famous for its vibrant nightlife and music scene, while Royal Street is celebrated for its art galleries and antique shops, neither of which feature the historic street railroad line associated with St. Charles Avenue.
