From the Friends of the Lafitte Corrior web site:
The Lafitte Corridor is the largely derelict strip of land in New Orleans, Louisiana, along the old Norfolk Southern Rail Line from Basin Street to Canal Boulevard next to St. Louis Avenue. Since the 1970s, planners have suggested turning this space into a public linear park and many residents in the surrounding neighborhoods have supported the idea.
The path of the proposed greenway follows a corridor which has been critical to transportation throughout New Orleans history first as a waterway & later as a rail line. There is no other direct route between Mid-City and Tremé, the Quarter and the CBD that is publicly-owned and generally undeveloped.
In post-Katrina New Orleans, with land use being re-examined throughout the City, supporters have realized the urgency of putting their idea into action. The long-term vision for the corridor is to develop a trail and park system (also called a greenway) that spans from the French Quarter to the Cemeteries.
