Since I live a block from the Arkansas River I drive up or down Riverside Drive every day. Tulsa was built on the curve of the river as it swings from East to South. Riverside Drive runs down the East side of the river from the center of town South for about 10 miles.
The area between the road and the river is the River Park. There is a running path which runs the length of it. At various locations are rest areas, playgrounds, several Frisbee golf courses, a rugby field, and places to fish. The city is in the process of making a lot of improvements to the park which explains the dirt work.
Actually the subject of this photo is on the opposite side of the riverat about 31st Street. This is one of the gas fired electrical generating plants that supply Tulsa with power.
