The new $336m Greenville Bridge over the Mississippi River in southeast Arkansas, US, will open in August this year.

The bridge connecting the US states of Arkansas and Mississippi will replace an existing bridge located 2,800ft downstream.

The Mississippi approach to the structure includes 1km of new roadway and 2km of approach bridge, and the Arkansas approach includes 1.2km of roadway and 1.4km of approach bridge.

The new bridge has three spans, four lanes of traffic, each 3.6m wide, a 4km bridge deck, two concrete towers, concrete piers and four fans of pre-stressing strand-steel cable.

The total length of the project, including the bridge, approaches and new roadway, is 6km or 3.84 miles according to ashleycountyledger.com.

The structure is touted as the fourth longest cable stayed span in North America and one of the longest bridge spans of any type on the Mississippi River.

The bridge, which took nine years to build, has been designed by Howard Needles Tammen and Bergendoff.
