The first highway through downtown Newberry was
M-25 which was assigned by July 1, 1919. M-28 replaced this designation by the end of 1927, when M-28 was extended eastward through the Upper Peninsula to end in downtown
Sault Ste. Marie. M-28 was transferred to a new roadway south of Newberry in late 1935 or early 1936 as shown on the
Michigan State Highway Department (MSHD) maps of the time. The segment of roadway between the new highway and downtown Newberry was given the M-28A designation. In downtown Newberry, M-28A followed
M-48 south, returning to M-28. The Bus. M-28 designation remained in place until late 1952 on maps. The April 15, 1953 MSHD map shows the highway turned back to local control. The concurrent M-117/Bus. M-28 segment was redesignated as just M-117. Later in 1953, M-117 was shown rerouted due south of Newberry, avoiding the jog along Webber and Miller roads. The segment of M-117 north of Newberry, including part of the former Bus. M-28 became part of an extended
M-123 by the publication of the 1962 MSHD map. ==Major intersections==
