After conducting research, I was not able to find any information about a boat ramp named Yankee Road in Iron County, Utah. It is possible that this boat ramp may not exist or may go by a different name.

However, there are several other boat ramps in Iron County that may be of interest.

One such boat ramp is the Newcastle Reservoir Boat Ramp, located at latitude: 37.5739962 and longitude: -113.2418453. This boat ramp services the Newcastle Reservoir, which permits boats with electric or gas motors. The reservoir is approximately 30 acres in size and the boat ramp is wide enough to accommodate multiple boats at once.

Another boat ramp in Iron County is the Navajo Lake Boat Ramp, located at latitude: 37.5705973 and longitude: -112.9082595. This boat ramp services Navajo Lake, which permits boats with electric or gas motors. The lake is approximately 3 miles long and 1 mile wide, and the boat ramp is wide enough to accommodate multiple boats at once.

It is important to note that regulations and restrictions may vary depending on the specific body of water and boating laws in Utah. It is recommended to refer to the Utah Division of Parks and Recreation website for the most up-to-date information on boating regulations and available boat ramps in Iron County.
