Greenville Bridge - Mississippi River

Project: US 82 Greenville Bridge
Location: Mississippi River Greenville, MS
Clients: Mississippi DOT, Kansas DOT
Designer: HNTB Corporation
JV Contractors: Massman Construction / Traylor Bros.

With more than 2-1/2 miles (4 km) of bridge deck, two concrete towers soaring 425 ft (130m) above the Mississippi River, concrete piers anchored 120 ft (36m) into the riverbed and four fans of pre-stressing strand steel cable, the new US 82 bridge at Greenville, Mississippi, is a spectacular crossing over America's most storied river. Loadtest completed a total of 8 O-cell tests on this project.

The bridge's main span of 1378 feet/420 meters is also the longest cable stayed span in the United States, the third longest cable stayed span in North America, and one of the longest bridge spans of any type on the Mississippi River.

Among the project's other features:

• The new bridge has three spans, of 591/1378/591feet (180/420/180 meters)
• The Mississippi approach to the bridge includes 2970 feet (905m) of new roadway and 6406 feet (1952m) of approach bridge.
• The Arkansas approach to the bridge includes 3752 feet (1143 m) of roadway and 4602 feet (1402m) of approach bridge.
• The total length of the project (bridge, approaches and new roadway) is 3.84 miles (6182 m).
• The new bridge is located some 2800 feet downstream from the previous bridge, greatly decreasing the likelihood of barge collisions.

The new bridge carries four lanes of traffic (two in each direction), each 12 feet wide. The bridge has a 12-foot outside shoulder and an 8-foot inside shoulder vs. two 12-foot lanes and no shoulders for the old bridge.
