M-218 was astate trunkline highway in the US state ofMichigan that served as a connector route fromInterstate 96 (I-96, originallyUS Highway 16, US 16) inWixom throughOakland County's lake country area toBusiness US 10 (Bus. US 10) inPontiac. M-218 was originally designated by 1936 and extended into Pontiac in 1938. The highway wasdecommissioned in 1963.
M-218 began at a junction with I-96 in Wixom. From there, the road traveled north via Wixom Road to 14 Mile Road and continued northeast. The trunkline then continued along Pontiac Trail through the communities ofWalled Lake,Orchard Lake Village,Keego Harbor andSylvan Lake inOakland County's lake country. Northeast of Sylvan lake, the highway crossedUS 10 (Telegraph Road) and crossed into Pontiac. M-218 terminated at a junction with Bus. US 10 in downtown.[2]
M-218 was proposed in 1936 as part of connection betweenChicago andPort Huron, Michigan.[5] As first introduced into theState Trunkline System by 1936, it served as a connector betweenM-58 in Pontiac and US 16 in West Novi.[1] In 1938, the route was extended into Pontiac where it terminated at US 10.[6][7] In 1958, plans for an extension to Northwestern Highway (nowM-10) toM-59 included an interchange to connect to M-218.[8]
In 1963, the highway was scheduled to receiving upgrades, including an expansion from two to four lanes between Keego Harbor and Sylvan Lake, elimination of sharp curves and the reduction of some steep grades along the highway. The cost was expected to be $1.6 million (equivalent to $12.5 million in 2024[9]), including the first phase already contracted at a cost of $512,964 (equivalent to $4.02 million in 2024[9]).[10] The second phase of work on the highway was bid in April 1963 to modernize 12.2 miles (19.6 km) at a cost of $609,018 (equivalent to $4.77 million in 2024[9]).[11] The trunkline was removed from the trunkline system by the end of 1963,[2][3] although it was still being mentioned in news articles as a location reference as late as 1978.[12]
The entire highway was inOakland County.
