After conducting research on Beech Bend Park Road boat ramp in Decaturville, Tennessee, it appears that there is limited information available about the ramp itself. However, here is what I was able to find:

- According to the website for the Tennessee Wildlife Resources Agency (TWRA), Beech Bend Park Road is one of several boat ramps located on the Tennessee River in Decatur County.
- It is not specified what kind of boat ramp it is (e.g. concrete, gravel, etc.), but a photo of the ramp on Google Maps appears to show a concrete ramp with a gentle slope.
- There is no information readily available on the exact width of the ramp.
- The TWRA website states that the Tennessee River is a popular waterway for boaters, and that many different types of watercraft are permitted on the river, including power boats, sailboats, kayaks, canoes, and more.

It's important to note that the information I found may not be the most up-to-date or accurate. It's always best to consult official sources like the TWRA or local authorities for the most current information on any boat ramp or waterway.
