A new international airport for New Orleans was also envisioned for the far eastern portion of Eastern New Orleans on several occasions. In the late 1960s, formal government-sponsored studies were undertaken to evaluate the feasibility of relocating New Orleans International Airport to a new site, contemporaneous with similar efforts that were ultimately successful in Houston (George Bush Intercontinental Airport) and Dallas (Dallas-Fort Worth International Airport). This attempt got as far as recommending a specific runway configuration and site in the East; a man-made island was to be created south of I-10 and north of U.S. Route 90 in a bay of Lake Pontchartrain. However, in the early 1970s it was decided that the current airport should be expanded instead. New Orleans Mayor Sidney Barthelemy, in office from 1986 to 1994, later reintroduced the idea of building a new international airport for the city, with consideration given to other sites in Eastern New Orleans, as well as on the Northshore in suburban St. Tammany Parish. Facing strong opposition from environmentalists, the "Times-Picayune" and many residents of the East, Barthelemy's idea came to nothing.
