U.S. Highway 90 Business (officially U.S. Highway 90-Z[1]) is a business route of U.S. Highway 90 in and near New Orleans, Louisiana, United States. Unlike a standard business route, it is built to higher standards than the segment of U.S. 90 that it parallels, with over half built to freeway standards and designated (but not signed as) Interstate 910. It crosses the Mississippi River on the Crescent City Connection (tolled eastbound) and runs along the Westbank Expressway west of the bridge and part of the Pontchartrain Expressway in the New Orleans Central Business District. On the other hand, U.S. 90 runs along surface streets through New Orleans, crossing the Mississippi on the older and narrower Huey P. Long Bridge.
[edit] Future
U.S. 90 Business is planned to become part of the Interstate 49 extension from Lafayette to New Orleans; the Interstate 910 designation is a temporary one. The American Association of State Highway and Transportation Officials (AASHTO) approved the extension of I-49 (as Future I-49) to Interstate 310 west of New Orleans on November 6, 1998,[3] and on October 1, 1999 the extension from I-310 to I-10 in New Orleans was approved. AASHTO requested "that Louisiana submit an application to AASHTO in accordance with the Federal Highway Administration's letter dated September 22, 1999 to sign the part of the route from I-10 in New Orleans to Ames Boulevard in Marrero as Interstate 910."[4] However, Louisiana did not follow through, and the road is not signed as I-910, nor considered I-910 by the Louisiana Department of Transportation and Development, which prominently calls it Future I-49.[5][6]
The freeway-standard Westbank Expressway extends from a temporary end between Westwood Drive and Ames Boulevard in Marrero to the Crescent City Connection in New Orleans. From the end of the freeway, past Westwood Drive and many other at-grade intersections, to the end of U.S. 90 Business at U.S. 90, the future frontage roads are known as the Westbank Expressway. The Expressway takes its name from its location, the West Bank of the Mississippi River.
