U.S. Highway 90 Business - Westbank Expressway

The Westbank and Pontchartrain Expressway portions of Business U.S. 90 double as hidden Interstate 910. The designation was approved by the American Association of State Highway and Transportation Officials (AASHTO) on October 1, 1999 for the freeway after a previous request to have the expressway incorporated to Interstate 49 was denied. The designation exists on paper only, as I-910 is not signed in the field nor referred to as such.

A major reconstruction project replaced the twin two lane viaducts of the Pontchartrain Expressway with the modern six-lane elevated freeway between 1993 and 1994. The roadwork resulted in the creation of the reversible HOV-2 viaduct that travels from downtown New Orleans to Gretna via the Crescent City Connection Bridge.

The twin cantilever bridges across the Mississippi River are referred to either as the Greater New Orleans (GNO) Bridge or the Crescent City Connection (CCC). The bridge is tolled in the eastbound direction at a cost of $1.00 per passenger vehicle. Electronic tolling via the GeauxPass system is available. The eastbound span opened in April 1958 with dual traffic. It was joined with a wider westbound bridge in September 1988.1
