The Detroit Department of Transportation (D-DOT) began introducing a route numbering system to identify its bus
routes in 1975. The new DDOT route numbers first began appearing on city buses with the arrival of DDOT's first fleet
of new buses — the GMC model T6H-5307A coaches (#1001-1148) — which began arriving in June of 1975.
The original DDOT route number configuration strictly arranged all routes in alphabetical order. Unlike its predecessor
(the DSR), DDOT utilized separate route numbers for its express bus routes. There also appeared to be an attempt to
better identify which major streets DDOT buses traveled along by increasing the use of hyphenated route names. For
example, the ambiguous Grand Belt line became identified as #20 GRAND BLVD.-McGRAW, while those routes like
Hamilton (which operated along two major streets) became #23 HAMILTON-W. 7 MILE. However, that practice was
later abandoned after the arrival in 1989 of the computerized route signs used on the #2000-series MCI Classics.
It appeared evident though that any attempt to make the route sign-curtains uniform across the entire DDOT bus fleet
remained a (system-wide) very low priority. Both DSR and DDOT route numbers continued to be displayed side-by-
side on DDOT coaches until the last of the former DSR coaches were finally retired during the early 1990s.
The following table compares the original DDOT route names and numbers in operation in 1975 with the current listing
of DDOT bus routes in operation today. Because various routes were added and discontinued through the years,
numerous changes appear between the two listings.
