M-100 is a north–south state trunkline highway in the central region of the U.S. state of Michigan. It runs between Potterville and Grand Ledge, connecting Interstate 69 (I-69) and I-96 west of the state capital, Lansing. The highway was previously a section of M-16. After M-16 was realigned, M-100 was created by 1927. Three extensions in the 1930s, 1950s and 1990s resulted in the current highway routing.
M-100은 Potterville에 있는 I-69의 66번 출구에서 시작합니다. 고속도로는 다운타운 남쪽의 US 27 번 고속도로 (US 27 번) 의 이전 루트였던 Lansing Road와 교차하는 Hartel Road를 따라 북쪽으로 달리고 있습니다. Hartel Road는 Potterville에서 Grand Ledge까지 정북쪽으로 뻗어 있습니다. M-43 (새기노 하이웨이) 북쪽에 있는 M- 100은 클린턴 스트리트를 따라가며 윌로우 하이웨이 북쪽의 제퍼슨 스트리트를 따라 북서쪽으로 조깅합니다. Bridge Street 에서 Grand River 를 건너면 M-100이 강 북쪽의 Clinton Street로 돌아옵니다. 마을 북쪽에 있는 이 도로는 Abrams Municipal Airport 근처에서 Wright Road로 변경되기 전에 Hartel Road로 다시 알려졌습니다. 이전 US 16의 경로인 그랜드 리버 하이웨이 북쪽 , M-100은 I-96을 만나 끝납니다. Wright Road는 인터체인지 북쪽으로 계속 이어집니다.
Like other state highways in Michigan, M-100 is maintained by the Michigan Department of Transportation (MDOT). In 2011, the department's traffic surveys showed that on average, 16,626 vehicles travelled along the highway in the city of Grand Ledge and 5,419 vehicles used the highway daily between Potterville and Grand Ledge, the highest and lowest counts respectively. No section of M-100 is listed on the National Highway System, a network of roads important to the country's economy, defense, and mobility.
M-100 was created in 1925 when M-16 was rerouted directly between Lansing and Eagle. M-100 started at M-39 in Grand Ledge and ran north to M-16 in Eagle. The highway was extended southward in 1932 to end at US 27/M-78 in Potterville. The northern end was extended to meet the US 16 (now I-96) freeway in 1958. The south was similarly extended in 1991 with the completion of the I-69/US 27 freeway south of Potterville.
