The name "Princeton" came from the old deeds from the neighborhood named Princeton Place Subdivision or Addition. Its outer edge on the west is rather closely paralleled by the River des Peres drainage works, whose valley creates a general downward slope to the west over much of the area. In earlier years Princeton Heights was drained by small creeks, one being Glaise Creek, which flowed into the River des Peres near the present location of Loughborough Avenue, south into the River des Peres ditch. Elsewhere the topography is quite rolling in character, with a high ridge crossing through the eastern portion of Kingshighway. The area has long been transversed by those coming to or from the downtown area of St. Louis. Gravois Avenue began as a road to a salt spring and ferry, near present-day Fenton, around 1804. In 1839, an act of the State legislature made Gravois a state road and during the 1840s it was paved with a macadam surface. In 1914, Gravois Road became the first concrete highway in Missouri, when six miles were laid from the downtown area to Grant's Farm. Gravois became known as Missouri State Highway 30 in 1922. During late 19th century, much of the area of Princeton Heights was farmland, and the area was known as "Gardenville". By the 1920s, most of the farmland was gone as housing developments and subdivisions emerged during the early urban sprawl of St. Louis. The Gardenville name lives on through a street name, school name, and the Gardenville Masonic Lodge in Affton.
