M-142 is a state trunkline highway in the Thumb region of the US state of Michigan. It is a "trans-peninsular" route in that it travels from Bay Port on Saginaw Bay to Harbor Beach on Lake Huron, thereby crossing the thumb peninsula.M-142 begins in Fairhaven, just a few miles south of Bay Port at an intersection with M-25. From there, the road travels east to Pigeon where the route turns briefly south before resuming its eastward trek. The road then continue eastward through Elkton and Colfax before reaching M-53. M-142 is then routed with M-53 to the town of Bad Axe. M-53 and M-142 part ways when M-53 travels off west and south while M-142 continues on eastward. Shortly after, M-142 meets up with M-19 at its northern terminus just east of Bad Axe.
