 The M @-@ 16 designation lasted for seven years . As the states were meeting with the American Association of State Highway Officials ( <unk> , now <unk> ) to plan the United States <unk> Highway System , the route of M @-@ 16 was originally planned to be included in US 18 . When the system was announced on November 11 , 1926 , Grand River Avenue and M @-@ 16 became part of US 16 . The first change to the US 16 routing in the Detroit area was made in 1933 when the highway was moved to bypass Farmington , with the old routing retained as a state highway .
