Mississippi Highway 844  Mississippi Highway 844 (MS 844) is a short highway near Crystal Springs, Mississippi. The route starts at Interstate 55 (I-55), and connects to U.S. Route 51 (US 51) east of the interstate highway. The road that became MS 844 was constructed around 1967, and was hidden in maps by 1974. Instead, a new loop near Crystal Springs was created. The route reappeared by 1998, and the section of MS 844 east of US 51 was transferred to the county by 2005. MS 844 starts at I-55 at a diamond interchange, and travels westward. The route then travels eastward shortly, before ending at US 51. The road, known as South Pat Harrison Drive continues on into Crystal Springs. In 2013, Mississippi Department of Transportation (MDOT) calculated as many as 910 vehicles traveling west of US 51. MS 844 is not included as a part of the National Highway System (NHS), a network of highways identified as being most important for the economy, mobility and defense of the nation. MS 844 is legally defined in Mississippi Code § 65-3-3, and is maintained by MDOT, as part of the state highway system. A paved road from I-55 to US 51 has existed since 1967, as sections of I-55 were being constructed. By 1974, it was removed from the state highway map. A new, locally maintained loop around Crystal Springs appeared in the same year. Around 1998, the short route between I-55 and US 51 became part of MS 844. The loop was transferred back to county maintenance in 2005, leaving the short road as part of MS 844.
