US 51 runs entirely parallel to Interstate 55 in Mississippi, rarely more than 4 miles from this highway. As a result, US 51 has no ongoing interest anywhere. US 51 in Louisiana already does, and comes from New Orleans. US 51 in Tennessee passes through Memphis. Because of the parallel I-55, US 51 is almost entirely single-lane, only part of Jackson is four-lane. In addition to I-55, US 51 also crosses Interstate 20 and Interstate 69.

US 51 was created in 1926. The route has not changed in Mississippi since. Except in the Jackson area, US 51 was then completely unpaved, consisting of a gravel road or dirt road. US 51 is of little importance for traffic within Mississippi, except for the capital Jackson, the route does not serve other major cities of the state. In the early 1930s, the first sections of US 51 outside the Jackson area were paved. Part of it was near McComb, from Jackson to Canton and near the Tennessee border. In 1936 most of the south of Jackson was paved, but the northern part was only partially paved. A final sprint was then made to paved the remaining sections of US 51, and by 1938 the entire route was paved.
Barely 25 years after US 51 was paved, construction of the parallel Interstate 55 began. The first part of this opened in 1960 at Jackson. The highway was built at a fairly rapid pace and was completed in 1974, eliminating the throughput of US 51 everywhere.
Every day, about 1,000 to 2,000 vehicles drive parallel to I-55 between the Louisiana border and Jackson, outside the various centers. In the south the route in McComb is somewhat busier with 11,000 vehicles. 12,000 to 20,000 vehicles drove through Jackson. In the north, only about 1,000 to 2,000 vehicles drive parallel to I-55, with only 500 vehicles per day on some stretches. This rises to 24,000 vehicles in Southaven, a southern suburb of Memphis.

The St. Louis Bay Bridge is a bridge in the United States, located in the state of Mississippi. The bridge is nearly 3.4 kilometers long and spans the Bay of Saint Louis between Bay St. Louis and Pass Christian.
The St. Louis Bay Bridge is a 3,380 meter long girder bridge. The bridge has 2×2 lanes and consists of a single bridge connection. Over the bridge, US 90 in Alabama runs from Bay St. Louis to Pass Christian. The bridge has mainly local importance, a little further north Interstate 10 runs a bit more inland.
The original road bridge opened to traffic in 1953. This was a narrow four lane bridge. The bridge was seriously damaged during Hurricane Katrina in 2005 and has since been replaced by a new bridge, which opened on May 17, 2007 after just a year and a half of construction time. This bridge is wider, although also with 2×2 lanes, but with emergency lanes and a bicycle/footpath on the south side of the bridge.
11,000 vehicles cross the bridge daily, mostly local traffic between Bay St. Louis and Pass Christian.
