M-78 is a state trunkline highway in the US state of Michigan. The western terminus is the intersection with M-66 north of Battle Creek in Pennfield Township. The roadway runs 10.744 miles (17.291 km) through rural farmland and the community of Bellevue as it approaches its eastern terminus at an interchange with Interstate 69 (I-69) near Olivet. The highway is used by between 3,100 and 5,300 vehicles on a daily basis.
When the state highway system was signed in 1919, M-78 followed a similar routing. At Bellevue, it turned northeast to terminate at Charlotte. In the 1920s, the highway was extended southerly to the Indiana state line near Sturgis and northeasterly into the Lansing area. In the 1930s, M-78 was extended further on its northern and eastern end to Flint. The highway was converted into a freeway in sections starting in the 1960s. During that decade, the southern extension from the 1920s was removed from M-78 and added to other state highways, and in the 1970s, the northeastern extensions, now mostly freeways, were removed from M-78 as well. Two special routes were created as a result of the various reroutings in the Lansing area, both of which are no longer part of the state highway system.
M-78 begins at an intersection with M-66 in Pennfield Township, north of Battle Creek in Calhoun County. The trunkline passes through rural farm lands as it runs due east and northeast. It briefly crosses the southeast corner of Barry County as it enters Eaton County. There M-78 follows Battle Creek Highway past some small ponds and into the town of Bellevue. The trunkline becomes Capitol Avenue in town and turns south onto Main Street in the middle of the central business district. M-78 crosses a branch line of the Canadian National Railway before leaving town. Main Street turns easterly and becomes Butterfield Highway. M-78 crosses the Battle Creek River before terminating at I-69's exit 48 in Bellevue Township.
