After conducting a thorough search, I was unable to find a boat ramp named Park Road 1 in Grand Prairie, Texas. It is possible that the name has been changed or that the ramp no longer exists. However, there are several boat ramps located in the Grand Prairie area that provide access to various bodies of water.

One such ramp is the Lynn Creek Marina Boat Ramp, located at 5700 Lake Ridge Parkway in Grand Prairie (latitude: 32.596582, longitude: -97.035224). This ramp is situated on Joe Pool Lake, a 7,400-acre reservoir located in the southern part of the Dallas-Fort Worth Metroplex.

The Lynn Creek Marina Boat Ramp is a concrete ramp that is 18 feet wide and has two lanes for launching boats. It is open year-round and provides access for a variety of watercraft, including boats, jet skis, and kayaks. There is a $10 fee to launch a boat, and parking is available for a fee as well.

In summary, there does not appear to be a boat ramp named Park Road 1 in Grand Prairie, Texas. However, the Lynn Creek Marina Boat Ramp provides access to Joe Pool Lake and is 18 feet wide with two lanes for launching boats. It is open year-round and permits various types of watercraft for a fee. Get driving directions.
