With a total length of 7,902 metres (25,925 ft), it is one of the longest bridges in the world.

[1] The bridge carries Interstate 310 over the LaBranche Wetlands[2][3] in St. Charles Parish.

The LaBranche Wetlands Bridge was constructed using a method known as "end-on construction" to avoid damaging the environmentally sensitive LaBranche Wetlands.

This is a top-down technique in which construction platforms are mounted on concrete piles to avoid disrupting the environment below.

The bridge won the 1992 Build America award in the Highway Division category.
