's former Twelve Mile Road
line was a relatively unknown suburban bus route that traveled 6-½ miles along East Twelve Mile Road, between South Macomb Community College (Twelve Mile at Bunert Road in the city of Warren)
and the former Madison Heights Shopping Center
on John R. in Madison Heights. Service on the line began on Monday, February 7, 1966. The Twelve Mile Road
line was one of only two DSR
bus routes to operate exclusively within the suburbs — the
other being the #65 Middlebelt
Westbound Twelve Mile coaches would begin at the Twelve Mile–Bunert Road parking lot loading zone at South Macomb Community College and would display a "Madison Center" metal sign in the front windshield, while eastbound coaches would begin boarding from the loading zone at the J. L. Hudson Budget Store in the Madison Heights Shopping Center. The eastbound coaches would display a "Macomb College" metal sign. Initially, coaches on the line were assigned out of both the Highland Park and Shoemaker DSR Terminals.
Originally, the service was operated by two coaches that provided 30-minute headways, Monday thru Saturday, from 6:30am until 9:00pm. However, by 1969, service had been reduced to 60-minute headways being provided by one coach. But unfortunately, route #88 Twelve Mile never attracted the ridership and was consequently discontinued on July 27, 1970, during DSR service cutbacks.
