Unfortunately, there seems to be an error in the question as Weeks Island Road is actually located in Louisiana, not Arkansas. It is a boat ramp located in Iberia Parish, Louisiana (latitude: 29.83655167, longitude: -91.79037476).

Weeks Island Road boat ramp is a concrete ramp that provides access to Vermilion Bay, which is a body of water located in the Gulf of Mexico. According to the latest information available, the boat ramp is approximately 14 feet wide and is suitable for launching small boats, such as skiffs, bass boats, and kayaks. Larger vessels may have difficulty launching from this ramp due to its size and limited facilities.

It is important to note that regulations and restrictions for boaters in Vermilion Bay may vary depending on the season, weather conditions, and other factors. Boaters are advised to check with the local authorities, such as the Louisiana Department of Wildlife and Fisheries, for the latest information on permitted craft and boating regulations in the area.
