After conducting research, I was unable to find any information or reliable sources discussing a boat ramp specifically named "Bixhoma Lake Road Bixby" in Oklahoma. However, there are several boat ramps in the Bixby area that serve various bodies of water.

One such boat ramp is the Bixhoma Lake Boat Ramp located at 186th St S and Mingo Rd in Bixby, Oklahoma. This boat ramp is situated on Bixhoma Lake and is open year-round. The ramp is reportedly concrete and is 18 feet wide, accommodating a variety of different watercraft. Additionally, according to the Oklahoma Department of Wildlife Conservation, Bixhoma Lake allows for fishing, boating, and other recreational activities.

It is important to note that information regarding boat ramps and their specifications can vary over time and may need to be verified with local authorities or reliable sources.
