Travel directions
The US 90 freeway near Houma.
US 90 in Texas comes from Beaumont and is initially double numbered with Interstate 10. From Toomey to Lafayette, US 90 runs directly parallel to I-10, mostly south of it. This region is low-lying and mainly consists of meadows with here and there forest areas. US 90 rejoins I-10 through Lake Charles and crosses the Calcasieu River here. East of Lake Charles, US 90 again parallels I-10 and leads through a series of small towns to the town of Lafayette. In Lafayette, US 90 exits south. The route through the city is one of Lafayette’s main roads and has 2×3 lanes, partly with a city block in the median strip.
From Lafayette, the road is initially a level 2×2 divided highway, but from near New Iberia it becomes a full-fledged highway. The highway leads through flat terrain through predominantly agricultural land in a southeasterly direction, parallel to the Bayou Teche. The agricultural land around US 90 narrows and is wedged between the swampy coastal region of the Gulf of Mexico and the swamps of the Atchafalaya Swamp. Between Centerville and Morgan City, the highway is interrupted by a section of divided highway with intersections. From Morgan City, US 90 becomes a freeway again and crosses the Atchafalaya River.
From Morgan City it follows a route through the swamps between the Atchafalaya River and the Mississippi River. Part of the great Louisiana delta, US 90 runs over embankments or bridges here, including a 5.5-kilometer girder bridge at Amelia and a 9-kilometer girder bridge west of Gray. The highway then passes just north of the city of Houma and from Raceland is no longer a highway, but again a 2×2 divided highway. At Des Allemands one crosses the bayou of the same name, after which Interstate 310 ends at US 90 at Boutte. From here one enters the urban area of the New Orleans region.
US 90 then crosses the south bank of the Mississippi River to Avondale, where the road branches north and crosses the Mississippi River at Metairie via the Huey P. Long Bridge. The road then continues as a 2×3 lane urban arterial through the western boroughs of the city of New Orleans. At the Louisiana Superdome, US 90 connects to a major interchange with Interstate 10 and US 90 Business.
Then US 90 forms North Broad Street through the north of the city. This is an urban arterial with 2×2 lanes. US 90 then crosses Interstate 610 and forms the Chef Menteur Highway in the eastern suburbs of New Orleans, a 2×2 lane urban arterial. East of New Orleans, US 90 runs through the coastal area that separates Lake Pontchartrain from the Gulf of Mexico. This area is swampy and almost uninhabited except for a series of boathouses along the water. US 90 is a single carriageway here and crosses the mouth of Lake Pontchartrain to the north bank via the Chef Menteur Bridge. After this, US 90 bypasses the town of Slidell and continues in the coastal swampy area to the Mississippi border formed by the Pearl River. US 90 in Mississippithen continues to Bay St. Louis and Gulfport.
US 90 Business
The US 90 Business in New Orleans.
There are multiple US 90 business routes in Louisiana, almost every major town has one. The most important is the Business Route of US 90 in New Orleans. This is a 23 kilometer route from Avondale to New Orleans. In Avondale, US 90 heads north over the Mississippi River via the Huey P. Long Bridge, while US 90 Business heads east through the southern suburbs of New Orleans. Initially this is an urban arterial with 2×3 lanes and a very wide median strip, in fact the frontage roadswithout a highway. From Marrero this highway does exist and is called the West Bank Expressway. This highway has 2×3 lanes and a high fixed bridge crosses the Intracoastal Waterway, while the frontage roads pass under the canal via the Harvey Tunnel. The highway then unlocks Gretna and then makes a long bend to cross the Mississippi River via the Crescent City Connection, a set of two large cantilever bridges. The highway leads on an overpass along downtown New Orleans and connects to Interstate 10 here.
History
US 90 at Lafayette.
According to ACRONYMMONSTER, US 90 was created in 1926, after which the Louisiana route was slightly modified. The biggest changes were the construction of highway sections in the Mississippi Delta, especially in the 1990s, when US 90 was largely grade separated. The Crescent City Connection in New Orleans opened in April 1958 over one bridge, which was doubled in September 1988. This is a toll connection, but only eastbound. On June 9, 1930, the Fort Pike Bridge opened over Lake Pontchartrain. This bridge was replaced by a new bridge on January 15, 2008. The Pontchartrain Expressway was built along downtown New Orleans between 1957 and 1962. The western part of this is now Interstate 10.
Until the early 1970s, Lafayette was the logical terminus for the east-west route, where US 90 veers south. Before Interstate 10 between Lafayette and Baton Rouge was built, there were no east-west connections over this corridor. Traffic had two options at the time, the US 90 that runs closer to the coast via Houma, or the then better developed route via the US 190 and US 61 via Baton Rouge, the so-called ‘Airline Highway’ that already covered 200 kilometers in the early 1950s. 2×2 lanes counted.
Texas – Lafayette
The route between the Texas borderand Lafayette has undergone relatively little modification or upgrade, despite Interstate 10 being built west of Lafayette only after 1960. The road was originally numbered LA-2, which was gradually modernized into a modern two-lane road between the 1920s and 1950s. However, few stretches have been widened to four lanes, primarily in the Lake Charles and Lafayette metropolitan area. The bridge over the Calcasieu River in Lake Charles opened to traffic in 1916, it was demolished after the Interstate 10 bridge was completed in 1952, and US 90 was routed over it. The westernmost 2.5 miles from the Texas border to Vinton has been eliminated because Interstate 10 has been built directly over it. As a result, there is only one bridge over the Sabine River at Orange, Texas.
Lafayette – New Orleans
Between Lafayette and New Orleans, US 90 has been constructed throughout with 2×2 lanes, large parts of which are freeway and some sections are 2×2 divided highway with at-grade intersections.
The first bridge over the Atchafayala River in Morgan City opened to traffic in 1933, the Long-Allen Bridge. US 90 went on for more than 40 years, until in 1975 the EJ “Lionel” Grizzaffi Bridge opened, a larger cantilever bridge close to the old Long-Allen Bridge, which has been used for local traffic ever since.
The first stretch between Lafayette and New Orleans to be widened to four lanes was a few miles east of Morgan City in the 1950s. In the 1960s and early 1970s, work was mainly done from Lafayette to Morgan City, by 1975 an entirely new route from Lafayette to Jeanerette was already in use, partly as a freeway. Also, the 2×2 section from New Orleans has been extended westward beyond Des Allemands. The section between Jeanerette and Morgan City was probably constructed in the second half of the 1970s or early 1980s as a new highway, which bypasses Franklin, among other things.
A major route adjustment has been carried out around the city of Houma. US 90 originally ran from Gibson via Houma to Raceland, but has been bypassed here by a freeway that cuts off the detour via Houma. Since then, US 90 has stopped passing through the town of Houma. This was probably built around 1990. There was a lack of 4 kilometers of freeway between Amelia and Gibson for a long time, this was only opened around 1998/1999. The Eastern Morgan City bypass was also only constructed in the 1990s.

Lake Pontchartrain Crossing
The first fixed road link from New Orleans to the east was the Maestri Bridge, which opened in 1928. US 90 passed through this for a short time, however it is now part of US 11.
The Chef Menteur Highway has been constructed east of New Orleans, which bridges over Chef Menteur Pass, a narrow strait between Lake Pontchartrain and the Gulf of Mexico. The Chef Menteur Highway opened to traffic over the Chef Menteur Bridge in 1929, the second section across the strait proper opened to traffic on June 9, 1930, with the opening of the Fort Pike Bridge. It was replaced by a new bridge between 2004 and 2008, construction was delayed by the impact of Hurricane Katrina in 2005.
West Bank Expressway
The first parts of US 90 to be widened into a 2×2 divided highway were the approach roads from the larger towns. In the 1950s, US 90 between Luling and Westwego was widened to 2×2 lanes just outside New Orleans. At the time, US 90 ran via the Huey P. Long Bridge to New Orleans. When the Crescent City Connection opened in 1958, the Westbank Expressway was constructed as a freeway serving as the Business Routeof US 90 was numbered. The Westbank Expressway in the suburbs of New Orleans was built between 1954 and 1960, including the Harvey Tunnel. Large viaducts over the Harvey Canal opened here in 1984, so that both a tunnel and a fixed bridge have been available since then. There have been plans to use the US 90 Bus. to be renumbered as Interstate 910, but this was never implemented. The main carriageways of the Westbank Expressway along Westwego were never built, despite the US 90 Bus central reservation. wide enough for it.
Future
US 90 between Lafayette and New Orleans may become part of Interstate 49 in the future.
Traffic intensities
Every day, 1,100 vehicles run parallel to I-10 west of Lake Charles. East of Lake Charles 4,000 to 6,000 vehicles drove because there are quite a few villages on the route. The four-lane New Iberia highway has 22,000 to 40,000 vehicles and 17,000 vehicles on the highway section from New Iberia to Morgan City. 28,000 vehicles drove through Morgan City. Some 18,000 vehicles and 34,000 vehicles west of I-310 drove past Houma. Some 24,000 vehicles ran between I-310 and the suburbs of New Orleans.
The West Bank Expressway traveled 68,000 to 73,000 vehicles and 156,000 vehicles on the Crescent City Connection over the Mississippi River. The Pontchartrain Expressway along downtown New Orleans has 123,000 vehicles. The route parallel to I-10 through New Orleans has about 25,000 to 30,000 vehicles and 19,000 vehicles east of I-510. East of US 11 there are still 3,500 vehicles left. 2,000 vehicles daily crossed the bridge over Lake Pontchartrain and 2,500 on the Mississippi border.
