U.S. Route 90 in Louisiana
U.S. 90 enters Jefferson Parish and, after passing Avondale, heads north at an intersection with the U.S. Highway 90 Business called the Westbank Expressway, through Bridge City, and across the Mississippi River over the Huey P. Long Bridge. Crossing the river U.S. 90, designated as S. Clearview Parkway, intersects with and runs east as the Jefferson Highway, that was originally part of the "Interstate Trail" and the "Pine to Palm" highway, a north/south transcontinental U.S interstate highway running from New Orleans to Winnipeg, Manitoba, Canada The highway terminus was at the corner of St. Charles avenue and Common street with a monument that was erected in 1916. The original highway was changed to follow U.S. 90 and Louisiana highway 48. After 1935 Jefferson became S. Claiborne Avenue at the Orleans Parish line and makes a sweeping south to north semi-circle weaving through New Orleans. As the highway swings north it intersects and runs under an elevated I-10, where it turns northwest along Tulane Avenue. The highway soon turns northeast along South Broad Avenue — North Broad Avenue after the intersection with Canal Street - then runs into a pair of regular individual streets (i.e., not a street that has a median - or "neutral ground" in the vernacular of New Orleans - separating half of the lanes from the other half) that are from the old street grid and thus parallel at about 120 yards from each other (named New Orleans Street & Allen Street) for about a quarter mile, crossing I-610 in this tiny span, and finally turning right (East) onto Gentilly Boulevard (which has a median), which eventually becomes Chef Menteur Highway (a mainly straight highway that replaced what is now called Old Gentilly Road), then crossing I-510, and then a few miles later, loses the median and meanders (i.e., in a manner similar to the way that Old Gentily meanders) until first reaching the southern terminus of U.S. 11, which leads to the Irish Bayou community, and then passing the Venetian Isles community (a subdivision in which homes have a canal in the backyard for easy access to the surrounding lakes), and finally becoming a 2 lane highway at the bridge over the Chef Menteur Pass to go past the Lake Catherine community until reaching the bridge over the Rigolets, after which U.S. 90 finally leaves the corporate limit of New Orleans, entering St. Tammany Parish. The stretch in the Lake Catherine community is where Jayne Mansfield was killed in a car accident on her way to New Orleans from Mississippi.
