According to U.S. Census records for
1900, the  population  of  Detroit  was
listed at
285,704, ranking the city the
13th  largest in the country.  By 1920,
its population had more than tripled to
993,678, ranking Detroit the nation's
4th most populated city. In addition to
the city's population boom, its borders
would also expand dramatically as well.
Between the years of 1915 and 1926,
the city's land area increased from just

 square miles  in 1915, to 139.2
square miles in 1926.  Detroit was able
to accomplish this feat  by annexing a
number of  the townships and villages
located just beyond the city limits.

It was  during this
massive annexation
period when a privately-owned motor-
bus company was formed  that would
soon establish a number of bus routes
out to those newly acquired territories.
The City of Detroit, at  that  time, was  
involved in a prolonged battle with the
Detroit  United  Railway  (DUR)
the  city's  privately–owned  streetcar
company — attempting to  take–over
(click on above map to view larger more detailed version)                                          
The first  Detroit Motorbus route to be put into service was  Rt 1-Jefferson Avenue,  which began operating on June
11, 1920 — charging a
10¢ bus fare. Its fleet of double–decker buses also competed with DUR streetcars along Jefferson
Avenue. Service operated along East Jefferson from Water Works Park (located at Jefferson and Cadillac) to Grand Circus
Park downtown. The following year, service along E. Jefferson was extended eastward to Continental Avenue — providing
service to the
Continental Motors, Maxwell Motors (renamed Chrysler, 1925), and Hudson Motor Car Co. plants.

After first having to rent garages to house  its bus
fleet, the company built its first bus garage on the
city's lower east side at Terminal Avenue and Edlie
Street,  just south of East Jefferson Avenue.  The
garage opened on July 15, 1921, and was able to
accommodate as many as
75 coaches.  After the
company's bus routes began to expand out  into
the  west-side,  two additional  west-side  garages
were built.  The first west-side terminal, located on
Tireman at Epworth, opened in July of 1923.  The
DMB's largest facility—-which included new offices
and a separate shop facility—-opened on April 11,
1924, on Dexter Avenue at Doris.

By early 1921, the
DMB had already begun using
its main line along East Jefferson to extend service
outward into the expanded city. An East Jefferson
branch out Cass Avenue, and  a  later branch  out
John R, provided service to the Burroughs Adding
Machine Company plant,  located  on  Amsterdam
and Second Avenue. Later that year, another East
Jefferson branch,  westward along West Lafayette
and  Green  Avenues,  was  added.  These  branch
extensions would later become separated from the
main East Jefferson line,  and would form the basis
for a number of
DMB bus routes—many of which
would remain in operation well into the
DSR years.

By the middle of 1921, the  
DMB  would  begin to
focus  a  number of  their bus routes around  two
major service hubs. One location was the massive  
Ford Motor Co. Model-T plant on Woodward at  
Manchester,  in the city of Highland Park.  Another
prim location would center around the area of the
15–story, block–long,
General Motors Building,
located at West Grand Boulevard and Second Ave.
City planners were hoping back then that the new
GM  Headquarters  (completed  in 1922)  would
become the focal point for a "second  downtown"
to be known as
"New Center."   The majority of
(click on thumbnail photos to view larger image)
the Detroit Motorbus Company's west-side bus routes provided service to the city's New Center area.

DMB's Rt 11-East Grand Blvd. — which was launched on December 11, 1923, and operated between E. Jefferson
(at Belle Isle) and the new General Motors Building — would become the last of the routes forming the company's network
of city lines. With the city-owned
DSR launching its own motorbus division in January 1925 — originally founded with the
intent to provide feeder-bus service to the city's newly acquired territories — the
successful bus company soon found its
ability to expand within the city had basically ceased.  In a move which would later have lasting impact today, the
Motorbus  Company
 decided to begin expanding aggressively out into the suburbs,  operating a number of suburban
routes from downtown to the outlying suburbs. It even acquired a number of smaller suburban bus companies.

Surprisingly though, the company's relationship with the city–owned
DSR was rather friendly at first,  with the DMB even
providing service periodically on behalf of the city.  Several
DSR routes, including Eight Mile, Fourteenth, Conant, and
West Warren, were briefly operated by Detroit Motorbus Company buses. By 1930, Detroit Motorbus was operat-
ing with a fleet of
395 buses, over a network of both city and suburban bus routes. However, the company's relationship
with the City of Detroit would soon change.

The arrival of the
Great Depression years which followed 1929 began to take its toll on the city-owned DSR system.  As
factories closed,  and patronage and revenues declined,  the city was forced to place a number of its buses and streetcars
into storage. To make matters worse, while most of the
DSR buses traveled routes in the outlying and more thinly settled
districts of the city, the
Motorbus Company buses served more densely populated areas. It was even reported that the
350-plus buses of the
DMB carried as many passengers as the almost six-hundred buses of the DSR. Consequently, with
the municipal system facing financial difficulties the Common Council ordered the
DMB to scale down a number of its com-
petitive routes, and to discontinue its
E. Jefferson route, which competed directly with the DSR, effective April 20, 1930.
However, after loud protests from riders, portions of the
DMB's Jefferson route was rerouted via Lafayette and Sheridan.   

In March of 1931,  a number of
Common Council members decided that instead of raising the fare to resolve the DSR's
financial problems, a take-over of the
Motorbus Company's routes might be a better solution, and instructed the Street
Railway Commission to study the issue and report within thirty days.  The Commission reported in favor of the acquisition
and was authorized by the Council to begin negotiations with the company. In July the
DMB offered to sell to the city the
buses and garages needed to operate its city routes for
$1,630,000, but the counter offer of $1,200,000 from the city
was turned down.  Negotiations between the Commission and the
DMB would continue on during the summer and fall of
1931, but would fail to produce an agreement.

Meanwhile, after the
DSR's receipts dropped by $2.5 million in 1931, Mayor Frank Murphy (1930-1933) declared that
"there had been enough delay" and the time had come to act. Murphy felt it was time to complete what
Hazen Pingree
James Couzens had begun by removing from Detroit streets the sole remaining private competitor of the DSR.  In
a hearing before the Council,
Mayor Murphy declared, "If municipal ownership is to survive in Detroit, it must be
municipal ownership only, one system over all our streets."
 The mayor had apparently turned the tide in favor of
an ouster, as the Council finally decided it must order the
Detroit Motorbus Company off the streets of Detroit.

On December 22, 1931, the Common Council voted to revoke the
Detroit Motorbus Company's day-to-day license to
operate within the city of Detroit, effective on the close of business on December 31, 1931.  As  a  result, effective  Friday,
January 1, 1932, the city-owned
DSR became the sole provider of both street railway and motor coach operations within
the city of Detroit. The
Detroit Motorbus Company, for the most part, had been put out of business.

Although the
Detroit  Motorbus  Company only operated within the city of Detroit from 1920 through 1931, many of
its city bus routes would remain in operation many decades later. Of the eight
Detroit Motorbus city lines in operation at
the end of 1931, all but its
Rt 1-Jefferson were continued on by the DSR. The following is a listing of the former Detroit
routes that were taken over by the City of Detroit, effective January 1, 1932.

that company's street railway operations.  With the city focusing more on the streetcar take–over, the increasing need to
provide an alternate transit service, that could reach from downtown out to these newly acquired territories, along routes
not serviced by streetcars, provided the ideal setting for the establishment of the
Detroit Motorbus Company (DMB).

Organized back in 1919 by Herbert Y. McMullen (an automobile accessory and supply distributor), the
Detroit Motorbus
would become the first permanently successful transit bus company to provide motor coach service within the
city of Detroit.  To help gain the support of the public as to the type of service it would be providing, the company began
operating a sample prototype double-decker bus on demonstrator trips to hotels, banks and department stores within the
central business district, and along Woodward Avenue. The promotion was a success, and even gained the support of the
local press.

The company began its operations in 1920 with a fleet of ten double-decker buses built by
Fifth Avenue Coach Co. But
unlike the
DUR, which had operated it streetcars through multi-year franchise agreements, the DMB was only licensed to
operate its service through so-called "day-to-day" revocable permits, issued by the Common Council.  Consequently, the
city could cancel the company's license at any time.

The DSR would also lease 62 coaches from the company's stockholders to operate the acquired service.  But despite the
fact that the company had been basically dismantled by the City of Detroit,
l the former DMB suburban operation still lives
on today through the suburban bus system
SMART (Suburban Mobility Authority for Regional Transportation).

After the company's city bus routes were captured by the
DSR in 1932,  its eastern suburban bus lines were acquired by
some of its management people who formed
Lake Shore Coach Lines.  Another group of DMB employees acquired its
western suburban lines, forming
Dearborn Coach Company which later became Intertown Suburban Lines in 1950.
That company became a subsidiary of American Transit Corp. in 1960, and was renamed
Metropolitan Transit in 1962.  
Both companies were later acquired a few years after the formation of the regional transit authority
SEMTA in 1967. The
Lake Shore lines were acquired by SEMTA in 1971 and Metro Transit in 1974. Today, many of these same routes are
run by the suburban
SMART bus system.

Continued on as the DSR's East Grand Blvd. line until June 22, 1950 when it merged with the former
Grand Belt line, forming the eastern portion of DSR/DDOT's route #20 Grand Belt (discontn'd 2009)
In 1920, the Detroit Motorbus Company became the first motor bus company to begin
operations in the city of Detroit. Its first route was along E. Jefferson Ave. Coach #934
in photo, was a 66-passenger semi-enclosed double-decker bus (model Z-F-204) built
by Yellow Coach in 1924. It is seen here boarding passengers in Grand Circus Park,
sometime between 1924 and 1929. Its destination sign reads "Jefferson–City Limits."
