The highway takes a generally southeast-to-northwest direction between Frankfort on Lake Michigan and Clare in the central part of the state. The northwestern end is at M-22 next to Betsie Lake; the southeastern end in downtown Clare is at an intersection with Business US Highway 127 (Bus. US 127) and Bus. US 10. In between, the trunkline runs about through woodlands, including areas that are a part of either the Manistee National Forest or the Pere Marquette State Forest. The highway also passes agricultural areas, several lakes in the region and a state park near Cadillac. M-115 was first designated in the 1920s on the northwestern end near Frankfort. Additional, disconnected sections were designed as part of the trunkline in the 1930s near Cadillac, Farwell and Mesick. All but one of these gaps (Cadillac–Mesick) was eliminated by the end of that decade. The remaining segment was built in the 1950s to unite M-115 into a single highway. The last change came in 1989 when the highway was extended into Clare to its current southern terminus. ==Route description== M-115 starts in downtown Clare at a four-way intersection with the two business loops, Bus. US 127 and Bus. US 10, in town. From this junction, M-115 runs west following the former routing of US 10 along Ludington Drive to Farwell. In the middle of town, M-115 turns northwesterly to meet the end of the US 10 freeway near Surrey Lake. The highway continues northwest through forest lands and lake country. The trunkline passes into northern Osceola County near its crossing of the Muskegon River. There are intersections with both M-66 and M-61 south of Marion near rural farms. The roadway subsequently crosses into southern Wexford County. Near Stone Lake south of Cadillac, M-115 meets US 131 and M-55. M-55 leaves the US 131 freeway and joins M-115, and the two run concurrently along the western end of Lake Cadillac. They separate near Lake Mitchell, and M-115 turns northwesterly between the two lakes passing Mitchell State Park and the eastern shore of the latter lake.〔〔 Past the Cadillac area, M-115 runs through the northeastern corner of the Manistee National Forest. The highway continues through woodlands, passing several small lakes in the area as it approaches the community of Mesick. There it turns due west and joins M-37 through town. After M-37 separates to the south, M-115 crosses the Manistee River and continues its northwestern course. The highway crosses the northeastern corner of Manistee County and runs through the community of Copemish on the way to Benzonia. The landscape here turns more agricultural as the highway skirts southwest of Thompsonville crossing the Betsie River.〔〔 After the river crossing, the highway enters Benzie County and runs through the Pere Marquette State Forest. South of Benzonia, M-115 runs concurrently with US 31 into town. The highways separate in the center of town where M-115 turns westward to run along the south shore of Crystal Lake past Frankfort Dow Memorial Field, the local airport near Frankfort. M-115 follows Forest Avenue, and the highway designation ends at the intersection in town with M-22 near Betsie Lake. The Michigan Department of Transportation (MDOT) maintains M-115 like all other trunkline highways in the state under its jurisdiction. As a part of these responsibilities, the department tracks traffic volumes along its roadways until a metric called average annual daily traffic (AADT). This number is a calculation of the traffic level along a segment of roadway for any average day of the year. In 2009, MDOT determined that the highest traffic levels along M-115 were the 12,079 vehicles daily along the section of highway near lakes Mitchell and Cadillac. The lowest AADT was the 2,236 vehicles near Copemish. The trunkline between the US 10 and M-37 junctions has been listed on the National Highway System. a network of roads important to the country's defense, economy and mobility. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「M-115 (Michigan highway)」の詳細全文を読む スポンサード リンク
