According to CITYPOPULATIONREVIEW.COM, the Huey P. Long Bridge is a cantilever truss bridge in the United States, located in Metairie in Louisiana.
The Huey P. Long Bridge spans the Mississippi River in Metairie, a western suburb of New Orleans. The bridge is a combined road/railway bridge with the railroad in the median strip and 2×3 lanes of US 90 in Louisiana on the outside. It is a large cantilever bridge. The road bridge is 2,462 meters long, the railway bridge has much longer bridges and is 7,009 meters long. The main span is 240 meters long. The bridge deck is 47 meters above the river. The bridge is not a freeway, but US 90 does have a grade separated intersection on both sides. The bridge is toll-free.
The Huey P. Long Bridge was built in the first half of the 1930s under the direction of Ralph Modjeski and opened to traffic in December 1935. It was the first bridge over the Mississippi River in Louisiana. The bridge replaced a ferry service and was instrumental in the development of the south bank of the Mississippi in the New Orleans metropolitan area. The bridge is named after Governor Huey P. Long who was murdered just before opening.
Between 2006 and 2013, the bridge was widened to 2×3 lanes. The project cost $1.2 billion and was the most expensive project completed in Louisiana to date. At the same time, grade-separated crossings were realized on both sides of the bridge. This also reduced the very steep gradients for road traffic on both sides.
In 2008, 43,300 vehicles crossed the bridge every day. In 2005, 52,400 vehicles still drove over the bridge. The intensities had dropped slightly due to the lengthy work that caused a lot of nuisance.

The Huey P. Long Bridge is a cantilever truss bridge in the United States, located at Baton Rouge in Louisiana. The bridge spans the Mississippi River.
The bridge is a steel truss bridge with cantilever construction and is a combined road/rail bridge. The bridge is 1,792 meters long (the bridges of the railway are longer) with a main span of 228 meters. The bridge spans the Mississippi on the north side of the city of Baton Rouge. The bridge has 2 lanes on both sides of the outside of the railroad bridge, the US 190 in Louisiana runs over it. The bridge is located in an industrial environment.
The bridge was built in the late 1930s as the first connection across the Mississippi to the capital Baton Rouge. The bridge opened to traffic in August 1940 and was Baton Rouge’s primary access road from then on. In 1968, the Horace Wilkinson Bridge opened as the second connection at Baton Rouge, over which Interstate 10 in Louisiana runs. Since then, the Huey P. Long Bridge has been especially important for regional traffic and industry. The bridge was once planned as part of Interstate 410, which was to form a northbound bypass of Baton Rouge. The highway was never built.
29,000 vehicles cross the bridge every day.
I-10 Twin Span Bridge
|I-10 Twin Span Bridge|
|Total length||8,700 meters|

According to ASK4BEAUTY, the I-10 Twin Span Bridge is an 8.7 kilometer girder bridge in the United States, located in the state of Louisiana.
The I-10 Twin Span Bridge spans the eastern portion of Lake Pontchartrain, about 20 miles northeast of New Orleans. The bridge connection is 8.7 kilometers long and consists of two parallel bridges with 2×3 lanes, with emergency lanes on the left, so a space reservation for 2×4 lanes. The bridge is east of the Maestri Bridge. Interstate 10 runs across the bridge from New Orleans to Slidell. The bridge is relatively low, usually with a vertical clearance of 9 metres, except at the bascule bridge where the clearance when closed is 24 metres. The bridge is toll-free.
Hurricane Katrina storm surge damage in 2005.
The first bridge at this location was built in the first half of the 1960s and opened to traffic on December 21, 1965 as part of Interstate 10. This bridge consisted of 433 spans of almost 20 meters and had a low clearance of 2.6 meters and a 20 meter high bascule bridge. This bridge consisted of two parallel spans. The bridge was seriously damaged during Hurricane Katrina in 2005, a large part of the bridge was pushed off the bridge piers by the storm surge that was higher than the bridge itself. A few weeks later, the eastern span was provisionally repaired so that 1 lane was available in each direction. As of January 6, 2006, both spans were back in use.
However, Katrina’s damage made it clear that the 1965 bridge was too prone to storm surges. On July 13, 2006, an $803 million project began to build a new double span east of the old bridge. This was put into use in phases. The new span also had 2×3 lanes, as opposed to 2×2 lanes on the original span. The eastern bridge was inaugurated on July 9, 2009, followed by the western bridge on April 7, 2010. On 9 September 2011, the project was fully completed. The new bridge is higher and sturdier.
In 2010, 45,400 vehicles crossed the bridge every day, which is well over capacity.
