Mississippi Highway 550
Mississippi Highway 550 (MS 550) is a state highway connecting Union Church and Brookhaven in southern Mississippi. The road travels through Jefferson and Lincoln counties. Route description. MS 550 begins at a Y-intersection with MS 28 in the community of Union Church, Jefferson County. The two-lane road heads southeast and later east through woodlands. The road crosses into Homochitto National Forest, enters Lincoln County, and crosses the Homochitto River. MS 550 winds through the national forest and reaches the settlement of Caseyville before formally exiting the forest's boundary. Continuing southeast, the road passes through  more open fields, reaching the unincorporated community of Loyd Star (formerly known as Redstar) and the attendance center (school) of the same name. As MS 550 approaches Brookhaven, it passes under Interstate 55 (I-55) without an interchange. It enters the city at the I-55 overpass. Passing a rehabilitation center and some businesses, it reaches an intersection with U.S. Route 51 (US 51) where a railroad bisects the intersection. Heading into the city center, the highway carries the names Union Church Road, Congress Street, and Schwem Avenue. The road ends at an intersection with West Monticello Street and Turnbough Avenue; the  former carries MS 184 east of here. History. A state maintained gravel road had existed connecting Union Church and Brookhaven since at least 1928. Some improvements were made to the road from this time to 1950 when it had formally received the MS 550 designation. By 1953, the entire route had been fully asphalt paved.
