D-DOT Route #93
In 1992, DDOT management announced that the following eight bus routes; Baker, Gratiot, Jefferson,
Joy Rd., Michigan, Oakland, Vernor
and Woodward, would no longer terminate downtown, but would
now be combined to form four new routes.  These lines were to provide
DDOT passengers with non-stop
"through–routing" service in-and-out of the downtown area.

Effective Saturday, September 5, 1992,
DDOT routes #34 Gratiot  and #37 Michigan  were combined
and through-routed out of downtown. This new combined service would be known as
Route #93
.   This would mark the third time that these two routes were combined.  The first
time was under the
DSR in November, 1950, when PCC streetcars operated along both lines,  and then
again in June, 1973, when both routes were combined under the
DSR, and continued a few years under
DDOT as route #34 Michigan-Gratiot.  

The new
Gratiot-Michigan line operated from Ford Rouge (Miller Road) Gate #2 on the west end, to the
Eastland Shopping Center on the east, although some Gratiot service terminated and looped downtown.

But despite the numerous problems encountered during the mid-seventies after combining service on
these same two bus lines,
DDOT management was determined to implement this on an even larger scale.  
Consequently, numerous service delays were encountered with the operation of these new lines being
assigned to two separate terminals.  Unpredictable coach and manpower shortages,  compounded with a
lack of communication between the terminal locations, resulted in numerous sporadic gaps within the

However, this combined routing arrangement didn't last long.  The service was discontinued, for the most
part, after  
DDOT and SMART  joined forces in a cooperative (albeit short–lived) route swapping project.   
Effective on Saturday, June 25, 1994,
SMART  took over operation

of DDOT's Michigan and Jefferson routes.  As a
result, the  combined
#93 Gratiot–Michigan and  
#97  Woodward–Jefferson   routes  were separated.

The cooperative agreement between
DDOT and
SMART  was  canceled after just nine months, after
SMART began campaigning to institute a suburban
transit tax to only support suburban bus service.  
Effective Saturday,  April 1, 1995,
DDOT  took  back  
the  operation of  its
#25 E. Jefferson  and  #37  
 routes,   while SMART resumed operation
of its routes along
Fort  Street  and  John  R.,  which  
had  been operated by
DDOT during the route
swapping project. After the termination of the
agreement with
SMART, the two line were never
rejoined and have since remained separate.
