The Street Index by The St. Louis Public Library, FOUND HERE, gives the historical origin of most street names in St. Louis City.
EXAMPLES:
CHEVROLET AVENUE (N-S):
In the General Motors Park subdivision of 1920, it was
named for the nearby Chevrolet plant. (Arlington)
LAFAYETTE AVENUE (E-W):
So named in the original 1836 platting of the St. Louis
Commons because it formed the southern boundary of Lafayette Park. It honors the
Marquis de Lafayette (1757-1834), the French general and statesman who aided
George Washington in the American Revolutionary War. He was enthusiastically
received in St. Louis during a triumphal visit in 1825. (Compton Hill)
(Lafayette Square) (Shaw) (Soulard)
Follows the former
Rue de Roi or Kingshighway along the western boundary of the Prairie des Noyers
Common Field. It became the main stem of the Kingshighway Boulevard system that
was adopted by the city in 1903. (Cabanne) (Central West End) (Clifton) (Grand
Prairie) (The Hill) (Oak Hill) (Shaw) (Southwest)
