Vassar and Caro. By July 1, 1960, the northern end was extended to run concurrently with M-25 and BUS US 23 to US 23 on the west side of Bay City. This M-15/M-25 routing was extended again in the next year to end at the new I-75/US 10/US 23 freeway. These two northerly extensions were both reversed and scaled back in 1970. M-15's northern end is moved back to M-25/Center Avenue in Bay City, its current location. At some time after the 1993 beginning of the program, M-15 was named the "Pathway to Family Fun" Recreational Heritage Route in what is now the Pure Michigan Byway System. Running roughly parallel to I-75, the route has not been added to the National Highway System, a system of roadways considered important to the nation's economy, defense and mobility. The state highway map in 1933 showed a proposed southern extension from Clarkston through southern Oakland County, Wayne County into Monroe County. This proposed highway would have bypassed Metro Detroit to the west through Farmington, Northville, Plymouth and Belleville. The full highway was never built, and M-15 was never extended south of Clarkston, but part of this proposal was completed. Much of it later became Haggerty Highway, and part of the I-275 and M-5 corridors. "Death Alley" M-15 between the Oakland County line and I-69 has been nicknamed by locals as "Death Alley". On April 17, 2009, The Flint Journal reported that between 2004 and April 2009, 14 people died on the stretch of road in car accidents. When Genesee County Sheriff Robert J. Pickell was asked about the stretch, he said the road suffers from a bad design, including a lack of turn lanes. He was quoted as saying, "It's a death trap". The Michigan Department of Transportation (MDOT) looks at roadways after every fatal crash to determine what improvements could be made. Other local government officials have called for solutions to safety issues on the roadway.
