M-343 is a state trunkline highway in Kalamazoo County, Michigan. It runs for almost eight miles (13 km) along Gull Road between the northeast side of Kalamazoo and continues through rural areas on the way to Richland. The highway was created in January 2019 from a section of M-43 after that highway was rerouted in the aftermath of a series of jurisdictional transfers in downtown Kalamazoo. It had been a part of the state highway system for a century under its previous number until it was given its current designation.
