In Moncton, Route 115 follows Elmwood Drive, a suburban arterial running due north from the city through the neighbourhood of Sunny Brae. The route continues north to the community of Irishtown, then northeast to Notre-Dame. From Notre-Dame, Route 115 turns north to the town of Champdoré, becoming known as rue Principale and chemin McKees Mills, then follows the south bank of the Little Bouctouche River to through McKees Mills as it ends in Saint-Francois-de-Kent.
History
Route 115 came into existence in 1965 as a renumbering of Route 31, during a mass redesignation of provincial highways. Until the late 1970s, Route 115 was routed from Notre-Dame eastward along present-day Route 535 to its former northern terminus in Cocagne.
