M-239 is a north–south state trunkline highway in Berrien County in the extreme southwestern corner of the US state of Michigan connecting State Road 39 (SR 39) in Indiana to Interstate 94 (I-94). The highway was designated in 1963, and it provided the only connection from the southern end of I-94 into Indiana until 1972.

Route description[edit]

As SR 39 crosses into Michigan it becomes M-239. As soon as it crosses the border, the road curves around to the northwest where it continues through a generally rural area. The trunkline intersects Wilson Road and passes next to a commercial development. After a little over a mile (1.8 km), the road comes to its northern terminus at an interchange with I-94 at exit 1. While M-239 officially ends at the interchange, the roadway, known as LaPorte Road, continues on to the northwest where it heads into New Buffalo.[2][3] Like other state highways in Michigan, M-239 is maintained by the Michigan Department of Transportation (MDOT). In 2011, the department's traffic surveys showed that on average, 6,231 vehicles used the highway daily.[4] No section of M-239 is listed on the National Highway System,[5] a network of roads important to the country's economy, defense, and mobility.[6]

History[edit]

M-239 always ended at I-94, even though La Porte Road continues into New Buffalo. Before completion of the Indiana portion of I-94, the freeway ended at the present exit 1. A 1.1-mile (1.8 km) stretch of La Porte Road was designated as M-239 in 1963 to carry traffic to Indiana State Road 39, which connects to the Indiana Toll Road.[7][8] Until 1972, when Indiana constructed their section of I-94, M-239 and SR 39 were the only connection from the southern end of I-94 in Michigan across the state line.[9][10]

Major intersections[edit]

The entire highway is in New Buffalo Township, Berrien County.
