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 US 90 and LA 48. After 1935 Jefferson became S. Claiborne Avenue at the
Orleans Parish line and makes a sweeping south-to-north semicircle 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 from each other (named New Orleans Street & Allen Street) for about , 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 national southern terminus of

History
The modern US 90 has its roots in an early 20th-century
auto trail known as the
Old Spanish Trail, which was designated as State Route 2 within Louisiana when the state first numbered its highway system in 1921. US 90 was applied to the route when the
numbered U.S. Highway system was implemented in 1926. With minor exceptions, Route 2 generally remained co-signed with US 90 throughout the state until such overlapping between U.S. and state routes was eliminated in the
1955 Louisiana Highway renumbering
In 1955, Louisiana passed a law that undertook a comprehensive revision to the state highway classification and numbering system. The new system designated roads by importance to travel patterns and rectified the previous numbering system under n ...
. Prior to 1955, as US 90 was gradually relocated onto newer and improved alignments, Route 2 was often moved accordingly. Former alignments remaining in the state highway system were then designated as part of
State Route 1092, with shorter pieces designated as Route 2-D, 2-E, and so on as needed.

*In Lafourche Parish, the old US 90 (now LA 182) splits off from the current US 90/Future I-49 just northeast of Raceland. Further southwest it enters Raceland, intersecting with LA 308, then immediately afterwards crosses Bayou Lafourche over a lift bridge. The route then goes to the right, through the middle of Raceland coaligned with LA 1 for a few thousand feet. It then takes a turn to the southwest as Willow Street or Old Houma Road, interchanging with US 90/Future I-49. Just south of this interchange, it travels as a four-lane highway until the junction with Prospect Blvd./LA 3087. Old Highway 90/LA 182 then heads to Bayou Blue and on to downtown
Houma as a major two-lane highway. LA 653 was US 90's original route but was supplanted in the 1950s by its current route, what is now LA 182, and most of this original road has been abandoned.

**1928–1930: US 90 was re-routed over the
Walnut Street Ferry in September 1928, shortening the route in Jefferson Parish to the former ferry landing at River Road and Sala Avenue in Westwego.
**1930–1937: US 90 was restored to its original route through Jefferson Parish in May 1930, after widening and resurfacing of the Westwego-Gretna section was completed in April.
**1937–1941: The Huey P. Long Bridge was opened in December 1935. US 90 was re-routed over the bridge, following Jefferson Highway into Orleans Parish, after widening of that thoroughfare to four lanes was completed in 1937. (LA 2 remained on the old alignment until the 1955 renumbering of Louisiana highways.)
**1941–present: The current alignment (the "
Boutte Cutoff") west of the Huey P. Long Bridge was opened in April 1941, bypassing the winding river road. This alignment was widened to four lanes in 1953.
*Orleans Parish (west of Peoples Avenue):
**1926–1928: US 90 originally followed this route through New Orleans, starting from the Jackson Avenue Ferry landing:
***Jackson Avenue and South Claiborne Avenue to downtown New Orleans.
***Canal Street, North Broad Avenue, Bruxelles Street, and Gentilly Boulevard to Peoples Avenue.
***The above route, though signed in the field, had several problems that were mostly alleviated by a re-routing in 1928:
****The
New Basin Canal bridge on South Claiborne Avenue had been closed in 1923 due to safety concerns. A temporary bridge was opened in July 1928, but it was a traffic bottleneck.
****Bruxelles Street became a one-way street in 1926, forcing westbound traffic to follow the unpaved Paris and St. Bernard Avenues from Gentilly to Broad.
****Jackson Avenue was also unpaved beyond St. Charles Avenue and did not connect directly to South Claiborne Avenue westbound.
****The Jackson Avenue Ferry service was considered to be inferior to that of the Walnut Street Ferry which the Old Spanish Trail had followed for years.
**1928–1930: The route of US 90 was revised above Canal Street in September 1928, utilizing a better ferry and avoiding the New Basin Canal bridge and railroad crossings on South Claiborne Avenue. From the Walnut Street Ferry landing, the revised route was as follows:
***Walnut Street, St. Charles Avenue to Lee Circle, Howard Avenue, and Camp Street to Canal Street.
***Because of one-way streets, westbound traffic followed Canal Street, St. Charles Avenue, and Audubon Street to the Walnut Street Ferry landing.
**1930–1931: In spite of protests, US 90 was routed back over the Jackson Avenue Ferry in May 1930, following Jackson Avenue, St. Charles Avenue, Washington Avenue, and South Claiborne Avenue to Canal Street.
**1931–1937: After Jackson Avenue was paved between St. Charles Avenue and South Claiborne Avenue in October 1931, the Washington Avenue detour was eliminated. Paving of Paris and St. Bernard Avenues was completed in March 1932, but eastbound traffic still followed Bruxelles Street.
**1937–1939: After being re-routed over the Huey P. Long Bridge, US 90 now entered Orleans Parish on South Claiborne Avenue, following South Carrollton Avenue and Canal Street to North Broad Avenue.
**1939–1946: US 90 shortly began to follow South Claiborne Avenue directly to Canal Street.
**1946–1956: The Bruxelles Street link was finally eliminated. Eastbound traffic now followed St. Bernard and Paris Avenues from Broad to Gentilly. Westbound traffic followed St. Bernard Avenue only.
**1956–1975: US 90 was re-routed over the North Broad Avenue extension and railroad underpass that had been opened in April 1952. Eastbound traffic was fed onto Allen Street to Gentilly Boulevard. Westbound traffic followed New Orleans Street from Gentilly Boulevard onto North Broad Avenue.
**1975–present: The final change in routing was the substitution of Tulane Avenue for Canal Street around 1975.
*Orleans Parish (east of Peoples Avenue):
**1926–1929: Continuing from the intersection of Gentilly Boulevard and Peoples Avenue, the original route of US 90 through eastern New Orleans was as follows:
***Old Gentilly Road to the
Industrial Canal. US 90 crossed the canal over the
L&N Railroad bridge (also known as the

***Current US 90 (Chef Menteur Highway) and old approach (described above) to Chef Menteur Pass.
***Current US 90 (Chef Menteur Highway) across Chef Menteur and Rigolets bridges to St. Tammany Parish.
**1932–1934: The Peoples Avenue-Downman Road section of Chef Menteur Highway, including a new bridge over the Industrial Canal, was opened in 1932. The original
Danziger Bridge existed on the north side of the current bridge.
**1934–1942: The permanent approach road to the Chef Menteur Bridge was finally opened, eliminating the road along Bayou Sauvage with right-angle turn onto the bridge.
**1942–present: The "Michoud Cutoff," the section of Chef Menteur Highway from Lee Station to Michoud, was opened in May 1942, completing the current alignment.
*In St. Tammany Parish, US 90 originally took a much longer route toward Mississippi. After crossing the Rigolets, US 90 traveled along LA 433 (Old Spanish Trail) to Slidell, then US 11 (Front Street) to Pearl River, continuing onto LA 3081 (Main Street). The bridge across the West Pearl River no longer exists. The route continued onto Old US 11, crossing the site of current US 11/I-59. Old US 11 continues through the Pearl River State Wildlife Management Area to the Mississippi state line, where a bridge once crossed the Pearl River. This out-of-the-way alignment was bypassed around 1930 when the current alignment to Pearlington was constructed. US 11 was subsequently routed onto it.
