 By the end of the decade, M-48 was truncated and rerouted on its western end, replacing the contemporary M-117 south of Rexton to US 2 in Epoufette.All of M-48 west of US 2 was turned over to local jurisdiction and removed from the state highway system, save a section made part of M-123 in late 1960 or early 1961.A few years later, M-48 was extended along a former section of US 2 into Rudyard to connect to the newly opened I-75/US 2 freeway in 1963.
