 The segments of the road between Brighton and Farmington were upgraded in 1956 . The MSHD initially signed the various freeways as <unk> in 1959 , and US 16 through the Farmington area gained the additional I @-@ 96 numbering . Two years later , the business route through Farmington was redesignated as a business loop of I @-@ 96 instead of US 16 . The final connection for I @-@ 96 between Lansing and Brighton was completed in late 1962 , and the US 16 designation was decommissioned in the state . The sections of highway through the Detroit metro area were given Business Loop ( BL ) or Business Spur ( BS ) I @-@ 96 designations .
