MS 15 and MS 67 head north, concurrent (overlapped) with each other, to have an interchange with both Sangani Boulevard and Promenade Parkway before crossing the Tchoutacabouffa River to leave D'Iberville and have an intersection with Lickskillet Road, which connects to Old Highway 67.
It is here where the highway passes by the Tradition Campus of William Carey University, as well as the Bryant Center of Mississippi Gulf Coast Community College.
Old Highway 67 splits off again (this time known as Success Road) to head north into the community of Success, while new MS 67 continues northwest through rural woodlands to cross Saucier Creek, as well as have an intersection with Bethel Road (Old Highway 67), before entering the community of Saucier and coming to an end at an interchange with US 49 at the northern end of town.
Highway 67 previously existed as a 2-lane road, starting at I-10 Exit 41 south of Woolmarket, and proceeding north past the village of Success, before turning west to end at Highway 49 about a mile south of its present terminus.
Construction on the Highway 67 relocation project began in 2002 and the road officially opened to traffic on January 16, 2009.
