The area that would become Main Street was originally a
plank road designed for travelers on horses. With the arrival of the
Wisconsin Central Railroad in 1871, a series of new businesses sprung up and the area began transitioning into Thiensville's new commercial center. Previously, the center of Thiensville's commercial activity was located to the east in what is now the
Green Bay Road Historic District. Business continued to grow on Main Street with the introduction of an
interurban in 1907. In 1915, the street was paved to accommodate
automobiles and several automobile-related business opened up in response. ==References==
