Interstate 910 Louisiana
Signed solely as U.S. 90 Business, Interstate 910 is the hidden designation for the West Bank Expressway and a portion of the Pontchartain Expressway in New Orleans. I-910 was established in place of Interstate 49, which may eventually extend east into New Orleans once it is constructed parallel to U.S. 90 between Lafayette and I-310 at Boutte.
The West Bank Expressway is a commuter route joining Westwago, Marrero, Harvey and Gretna with the New Orleans central business district via the Crescent City Connection Bridge. The Mississippi River crossing was tolled until March 2013, when a court ruling suspended toll collection. The toll plaza remained in place until June 8, 2016, when demolition work started.1

U.S. 90 Business in New Orleans was designated as a part of Future Interstate 49 in 1991 by federal legislation. Kam Movassaghi, secretary of the Louisiana Department of Transportation and Development (LADOTD), requested federal officials in May 1999 to formally label both U.S. 90 Business in New Orleans and in Jefferson Parish along the Westbank Expressway as part of Interstate 49. The request also included adding the limited access section of U.S. 90 from Raceland to Berwick as part of I-49. Federal officials rejected both in September 1999 because neither were connected to the existing Interstate 49. Instead officials offered to make the New Orleans segment a spur of I-10 until I-49 is extended.2
The Interstate 910 was approved by the American Association of State Highway and Transportation Officials (AASHTO) on October 1, 1999. The Interstate Route Log and Finders List published by the Federal Highway Administration (FHWA) on October 31, 2002 listed I-910 as an Auxiliary Route with 9.70 miles.
Subsequent actions by LADOTD for I-910 from an January 2003 email indicated that signing the route was still a possibility:3
The signing of the Westbank Expressway as I-910 is still on hold due to the inclusion of this section of highway in the Future I-49 Corridor. The Department is about to initiate work on an Environmental Impact Statement for 37 miles west of the Westbank Expressway. At the conclusion of that study, we will be in a better position to determine how to proceed.
Since that time, the Interstate 910 designation remains unsigned and no further plans to post it were announced. As originally envisioned, I-49 South will extend southeastward from Lafayette to Morgan City, east to Houma and east northeast to the Westbank Expressway and New Orleans. The east end remains uncertain, as I-49 South may instead turn northward at Boutte and overtake Interstate 310 to end at I-10 by Kenner. Should that be the case, I-910 may remain indefinitely along U.S. 90 Business.
