Natchez-Vidalia Bridge (Natchez, MS)

 

Located about halfway between Baton Rouge and Vicksburg near the city of Natchez, the Natchez-Vidalia Bridge crosses the lower Mississippi River between southwest Mississippi and northeastern Louisiana at the city of Vidalia. This river crossing is a dual span, which creates an interesting visual effect that is atypical on the Mississippi River in general.

Construction on the original bridge took place in the late 1930s in conjunction with a much larger parallel effort by the U.S. Army Corps of Engineers to strengthen the area’s flood protection and levee system along the Mississippi River. One of the more ambitious aspects of this plan was to relocate the city of Vidalia to a location of higher ground about one mile downriver from the original settlement. The redirection of the river through the Natchez Gorge (which necessitated the relocation of the town) and the reconstruction of the river’s levee system in the area were undertaken in the aftermath of the Great Flood of 1927, which devastated communities and farmland all throughout the Mississippi Delta region. In response to this disaster, the federal government passed the Flood Control Act of 1928, which gave absolute power to the U.S. Army Corps of Engineers to design and maintain a flood protection & levee system for the Mississippi River. The elimination of a prominent oxbow bend in the river across from the Natchez Gorge and the associated relocation of the city of Vidalia was one of the largest projects undertaken by the Corps in the 1930s as part of the larger risk-reduction effort along the lower Mississippi River.


The dual spans of the Natchez-Vidalia Bridge reflect 50 years of engineering progress in design and construction of bridges along the lower Mississippi River.

The new bridge connected the new city of Vidalia with the old river town of Natchez when it opened in 1940. Over the years, the bridge became important as a linchpin in the region’s US Highway system, even in the years following the creation of the interstate highway system and the original bridge’s narrow roadway (its travel lanes were reported to be as narrow as 8 ft and the bridge’s roadways lacked shoulders or other safety measures). Traffic demands in the area warranted the construction of a parallel span, which opened to traffic in 1988. Under the current configuration, westbound traffic crosses on the original 1940 bridge while eastbound traffic crosses on the new bridge. The parallel span was built wider than its predecessor and features modern shoulders and standard-width travel lanes. Both spans were built to similar proportions and appear to be identical on first glance. Each structure is about 4,200 ft long from abutment to abutment and they feature steel truss superstructures over ½ mile in length. The four cantilever bridge towers are the focal points that support the three longest spans of the superstructure, each about 850 ft long. The roadways stand upwards of 125 ft above mean river level, making them the tallest bridges in the state of Mississippi.

This bridge is located near a significant crossroads of the US highway system, one of the more robust such locations in the deep south. When the first span of the bridge opened in 1940, it was part of US Highways 65 and 84 and these two highways have been most closely associated with the bridge over the years. As of 2024, the bridge carries US Highways 84 and 425 and is located near prominent intersections with US Highways 61, 65, and 98. US 65 crossed the Mississippi River on this bridge until 2005 when its southern terminus was relocated to Clayton, LA. At around the same time, US 425 was extended eastward over the Mississippi River to end at US 61 in Natchez. US 98 begins at US 61 on the north side of Natchez, a short distance from the eastern bridge approach.

Horace Wilkinson Bridge (Baton Rouge, LA)

Standing tall across from downtown Baton Rouge, the Horace Wilkinson Bridge carries Interstate 10 across the lower Mississippi River between West Baton Rouge and East Baton Rouge Parishes. Unusually, the bridge is actually named for three separate people; three generations of Horace Wilkinsons who served in the Louisiana State Legislature over a combined period of 54 years. Constructed in the 1960s and opened to traffic in 1968, this is one of the largest steel bridges on the lower Mississippi. It’s also the tallest bridge across the Mississippi, with its roadway reaching 175 ft at the center span. Baton Rouge is the northernmost city on the river where deep-water, ocean-going vessels can operate. As a result, this bridge is the northernmost bridge on the river of truly gigantic proportions. Altogether, the bridge is nearly 2 ½ miles long and its massive truss superstructure is 4,550 ft long with a center main truss span of 1,235 ft. The Horace Wilkinson Bridge is one of the largest

Sunshine Bridge (Donaldsonville, LA)

Located about halfway between Baton Rouge and New Orleans in southern Louisiana, the Sunshine Bridge spans the lower Mississippi River near the city of Donaldsonville as part of the longer Louisiana Highway 70 corridor, which connects Interstate 10 and Airline Highway (US 61) with US 90 in Morgan City. In the years following World War II, the only bridges across the lower Mississippi River in Louisiana were located in the area of the state’s two largest cities – Baton Rouge and New Orleans. Postwar agricultural and industrial development along the river in this region led to the planning of a series of infrastructure projects in southern Louisiana that were aimed at spurring this development and modernization of the Delta region. One of these projects was known as the Acadian Thruway and was developed in the 1950s as a toll road intended to connect greater New Orleans with Lafayette and points west while providing a high-speed bypass of the Baton Rouge metro area. The Thruway, which
