JenksJenks began in 1904 as a community site established by the Midland Valley Railroad between Tulsa and Muskogee, alongside the Arkansas River. Though the river could only be utilized by shallow draft steamboats while the water level was up, these two transportation routes proved vital to Jenks' early development.
Jenks was named after William Henry Jenks the owner and director of the Midland Valley Railroad. According to a 1957 article in the Tulsa Tribune, an agent for the townsite company was told by the railroad home office to name a town for the director.
The town was officially platted on July 15, 1905. Also in 1905, a major petroleum discovery was made, further bolstering the economy of the area. The "Glenn Pool" oil well and subsequent oil claims brought many business people to the general area. In 1906, many oil depots were constructed in Jenks. By the time of statehood, Jenks had 465 inhabitants.
From 1904 through the 1950s, Jenks experienced many floods from the overflow of the Arkansas River and Polecat Creek. In the 1920s and 1930s floods were very severe. During one flood in the late 1920s the water was so deep that it completely covered every building but the roof of the three story high school. In 1948, the U.S. Army Corps of Engineers built a levee around Jenks, and the community subsequently grew as a result of the increased safety and security.
Jenks has served as a river crossing point via several bridges over the past century. In 1910, a single-lane bridge was built and strengthened the economic success of the area. 1948 saw the construction of a replacement two-lane bridge which still stands today and now serves as a pedestrian crossing between the Riverwalk and the South Tulsa River Parks. A four-lane bridge was built in 1996.
