The Lake Pontchartrain Causeway, generally called The Causeway, is a fair association made from two equivalent expansions crossing Lake Pontchartrain in southeastern Louisiana, United States. The length of the two expansions is 23.83 miles (38.35 km) long. The southern finish of the gatekeeper is in Metairie, Louisiana, a south coast suburb of New Orleans. The northern end is in Mandeville, Louisiana, a North Coast suburb of New Orleans.

Beginning around 1969, it was recorded by Guinness World Records as the longest steady platform over water in the world; In 2011, due to the send off of the more Jiaozhou Bay Bridge in China, Guinness World Records made two classes for ranges over water: endless and outright length over water. Lake Pontchartrain Causeway then, at that point, transformed into the longest framework over water (incessant), while Jiaozhou Bay Bridge transformed into the longest augmentation over water (outright).

The frameworks are maintained by 9,500 significant pilings. The two frameworks have a bascule, which extends 8 miles (13 km) from the north bank southward of the course channel. For additional comparable updates visit longests.


The chance of a platform crossing Lake Pontchartrain follows as far as possible back to the mid nineteenth hundred years and the trailblazer behind Mandeville, Bernard de Marigny. They started a boat organization that happened until the mid-1930s. During the 1920s, a suggestion required the arrangement of phony islands, which would later be related by a movement of augmentations. Funding for the arrangement would come from selling local regions on the islands. At the point when the endeavor was achieved by Ernest M. Loeb Jr. in 1948, the improvement of the high level bridgehead began. Because of his crusading and vision, the Louisiana Legislature made what is presently the Causeway Commission. The Louisiana Bridge Company was outlined to develop the platform, which selected James E. to facilitate the endeavor. Assigned Walters Sr. Ernest M. Loeb was named after his nephew, Ernest M. Loeb. Loeb III, Ernest M. The head of Loeb and Company assisted with organizing the improvement of the expansion.

The main highway was a two-way range, with a length of 23.86 miles (38.40 km). It opened in 1956 at a cost of $46 million (indistinguishable from $340 million out of 2020 bucks). This incorporated the framework, yet three access roads at the northern end and a lengthy length of road at the south end.

On June 16, 1964, six people were killed when a channel burst in the platform and a vehicle fell into the lake.

An equivalent two-way range, 0.01 mi (16 m) longer than the first, was opened on May 10, 1969 at a cost of $30 million (similar to $170 million out of 2020 bucks).

Since its turn of events, the platform has filled in as an expense range. Till 1999, tolls were accumulated from traffic heading down each way. To decrease blockage on the south bank, cost collection on the north side was dropped. In May 1999, the standard expense for vehicles was changed from $1.50 in every direction to the $3 cost accumulated on the North Shore for toward the south traffic. In 2017, the expense was raised to fund security upgrades for the expansion. The expense changed from $3.00 in genuine cash and $2.00 with the expense tag to $5.00 with cash and $3.00 with the expense tag.

Guinness World Record Controversy

From here onward, indefinitely a truly lengthy timespan the Lake Pontchartrain Causeway was recorded by Guinness World Records as the longest framework over water on earth. In July 2011, the Jiaozhou Bay Bridge in China was named by Guinness World Records as the ‘longest framework over water’. There was some conflict in the United States at the time as partners of the past holder of the record, Lake Pontchartrain Causeway, went against Guinness World Records not considering the lane the longest. Advocates set up this case concerning its definition, for instance the length of a framework over water, and construed that Lake Pontchartrain Causeway connected for 23.79 miles (38.28 km), and was consequently the longest. The Jiaozhou Bay Bridge crosses simply 16.1 miles (25.9 km) of water. In any case, Guinness World Records, using assessment norms that integrate outright plans, for instance, land ranges at the terminations and an undersea section, communicated that the Jiaozhou Bay Bridge is 26.5 miles (42.6 km) long. Following this discussion in July 2011, Guinness World Records made two classes for ranges over water: constant and full scale length over water. Pontchartrain Causeway Lake then, transformed into the longest augmentation over water (steady), while Jiaozhou Bay Bridge transformed into the longest platform over water (full scale).
