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 and busiest bridges on the lower Mississippi River. As time has gone on, it's become clear that this bridge is not capable of handling the ever-increasing cross-river traffic demands of the region.

As part of the busy I-10 corridor across southern Louisiana, this bridge sees some of the heaviest traffic of any bridge on the lower Mississippi. This problem is compounded by the fact that for a metropolitan area the size of Baton Rouge (the state’s capital and 2nd largest metro area), cross-river traffic is handled by only two bridges, the other being the much older Huey P. Long Bridge a short distance to the north. The high amount of local traffic mixing with the already significant long-distance traffic on the interstate makes for a bridge that is always prone to congestion at all hours of the day. In addition, the bridge’s roadway lacks full shoulders, a common safety feature on most interstate highway bridges. The roadway does carry six lanes for traffic, yet two of these lanes (one per direction) are reserved for local entering/exiting traffic at the interchanges on each bridge approach. 

Altogether, this is a bridge that has needed supplementation for many years and the state of Louisiana is not in a position at this time to offer any significant solutions to the traffic bottleneck that the bridge and its approaches represent. The state has instead chosen to pursue bridge projects in other areas of the lower Mississippi basin that have had negligible impacts on traffic congestion, whether in the Baton Rouge area or elsewhere, and the state has generally neglected the needs of its capital region by overlooking the traffic demands generated in this particular stretch of the river. In this author’s opinion, southern Louisiana would be well-served to consider the construction of a third bridge in Baton Rouge, whether as a parallel span for the existing Wilkinson Bridge, or on an alignment nearby that would enable much of the long distance traffic on the interstate to bypass Baton Rouge. The two bridges that serve this area are not getting any younger and it may be time to take their age and lessening effectiveness seriously so that a real effort may emerge to modernize the region’s transportation infrastructure with the goal that it will be compatible with the demands of the 21st Century.

They have opened the lanes going over the bridge to two lanes however it must squeeze to one merging lane when it gets to the I110 coming from the north. While the I-110 continues with 2 lanes. I-110 is a smaller less traffic interstate. This needs to change. Open up I10 to continue on with 2 lanes merging with only 1 lane entering from I-110. Then I 10 would continue to flow with the 2 lanes

I just need to know when those photos were taken bc this is by far THE BEST I’ve ever seen traffic ������
If you happen to be sitting at a standstill (a frequent occurrence) at the top of this bridge 175 feet above the river, you will feel the bridge noticeably shake with the heavy truck traffic. Scary.

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

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, wh
