[1] MS 822 officially begins at the intersection of Clay Street, Old Highway 27, and the entrance to Vicksburg National Military Park.

Continuing east as a divided city-maintained highway, state maintenance begins about 450 feet (140 m) afterwards at an I-20 frontage road.

The road, still known as Clay Street, travels past a few stores before intersecting MS 27.

[6] The route continues to parallel I-20, and gradually closer to a railroad owned by Kansas City Southern Railway.

Shortly after I-20 begins to travel northeastward again, MS 822 reaches its eastern terminus at the end of state maintenance.

[19][20] Twenty-four years later, in 1998, US 80 in Warren County was realigned onto I-20, and the alignment between Vicksburg and Bovina became MS 822.

Heading east from the start of state maintenance, the highway reaches I-55 at a diamond interchange, and travels westward.

[30] In 2013, Mississippi Department of Transportation (MDOT) calculated as many as 910 vehicles traveling west of US 51.

[3] MS 844 is legally defined in Mississippi Code § 65-3-3,[5] and is maintained by MDOT, as part of the state highway system.

[31][22] The loop was transferred back to county maintenance in 2005, leaving the short road as part of MS 844.
