According to Act-test-centers, US 190 is a US Highway in the US state of Louisiana. The road forms an east-west route through the south of the state, from the Texas border through the capital Baton Rouge to Slidell. US 190 is 454 kilometers long in Louisiana.
The nearly 6 km long Morganza Spillway Bridge.
The Huey P. Long Bridge over the Mississippi River in Baton Rouge.
According to liuxers, US 190 begins on the Texas state border formed by the Sabine River. US 190 in Texas comes from Jasper, a sparsely populated region of East Texas. The first section in Louisiana also passes through densely wooded areas with few larger towns. Two-lane US 190 follows an illogical route, first northeast to DeRidder, then nearly 25 miles south to near Dequincy, then east. The north-south section coincides with US 171. In Kinder one crosses the US 165. East of Kinder, the area becomes more open, with flat meadows, interrupted by some wooded riverbanks. From Basile, the US 190 is a 2×2 divided highwayand passes through the town of Eunice. Another 30 kilometers to the east you reach Opelousas, the first important place on the route.
In Opelousas, US 190 runs through downtown on two one – way roads and connects to Interstate 49 on the east side of town. The US 190 is then also a 2×2 divided highway and then leads through the delta of the Mississippi River. West of Krotz Springs, US 71 connects. At Krotz Springs, one crosses the wide Atchafalaya River via two parallel bridges. This is followed by the less noticeable, but 6 kilometer long Morganza Floodway Bridge. This is followed by another stretch through meadows, after which you reach the bank of the Mississippi River 40 kilometers to the east. The Huey P. Long Bridge crosses the river to the capital Baton Rouge. The bridge has 2×2 lanes with a railway line in the middle.
A very short stretch of US 190 has been constructed as a quasi freeway, with a 4 level stack interchange with Interstate 110 in the north of Baton Rouge. US 190 then merges with US 61 to form a major 2×2 lane urban arterial through east Baton Rouge. There are also two clover leaves. At the cloverleaf at The Mall at Cortana, US 190 turns east. The US 190 then forms a 2×2 divided highway with frontage roads through the eastern suburbs of Baton Rouge. This is actually a level highway. Cross the Amite River at Denham Springs.
East of Denham Springs, the development begins to become less dense and forests take over. US 190 runs parallel to Interstate 12 a short distance away. East of Walker, US 190 is mostly a single-lane road. There is a connection to I-55 near the town of Hammond. The road heads east through the town of Covington and runs north-south between Covington, I-12 and the Lake Pontchartrain Causeway. US 190 then runs over the north shore of Lake Pontchartrain, south of I-12. The road then passes through Slidell, connects to I-10, and ends just east of Slidell on US 90.
Created in 1926, US 190 originally ran only from Baton Rouge to Slidell, but was extended into Texas in 1935. In 1933, the Krotz Springs Bridge opened over the Atchafalaya River at Krotz Springs. This bridge was replaced by a new one in 1973 and doubled in 1988 by building a second bridge next to it. In August 1940, the Huey P. Long Bridge opened in Baton Rouge over the Mississippi River. In 1945, the six-mile four-lane Morganza Floodway Bridge opened east of Krotz Springs. US 190 partly formed the historic Airline Highway from New Orleans to Krotz Springs, which was largely formed by US 61. The section from Krotz Springs to Baton Rouge coincided with this and was the longest 2×2 toll-free section in the United States in the 1950s.
In the 1940s, US 190 passed through Baton Rouge in a different way. This route ran along Florida Boulevard through downtown and along the Mississippi River. In 1960 the Baton Rouge bypass was completed and US 61 and US 190 were routed over the bypass. The former route has since been a Business Route of both US 61 and US 190. The Baton Rouge bypass was later significantly developed, resulting in many traffic lights. In 1976, the Cortana Mall opened at the cloverleaf between US 61 and US 190 in eastern Baton Rouge. This was once one of the largest shopping malls in the United States, but has been largely empty since 2016.
3,600 vehicles drive daily at the Texas border, rising to 6,700 at DeRidder. The double numbering with US 171 south of DeRidder has 5,800 vehicles. Further east, 2,000 to 6,000 vehicles drive as far as Eunice. Between I-49 and Baton Rouge there are 11,000 to 18,000 vehicles. At Baton Rouge, 28,000 vehicles drive on the Mississippi River and 46,000 to 54,000 vehicles on the double-numbered section with US 61. In the east of Baton Rouge, the intensities drop to about 25,000 vehicles. Parallel to I-10 to Hammond, 6,000 to 11,000 vehicles and 4,000 vehicles continue as far as Covington. This rises to 67,000 vehicles between Covington and I-10 at Mandeville. This drops sharply east again to 11,000 vehicles to Slidell and 2,400 vehicles before the intersection with US 90.
