yes, both gates are closed as of last friday 4/24. you can go past the gates with a skinny bike. the bridge is open to foot traffic, and has a warning that it's a 0 ton weight limit. rayhouse rd. from hwy16 to the county border is not maintained, but also not abandoned, thus still belongs to the county and is a public road, a such. as far as I know, it's OK to walk and ride bicycles on it, but I don't know the legality of riding motorcycles on it.
in the past, the gates open mid-may, I don't know if they will open now.
