Under construction from July 1 2018 until December 31 2020. But it's all still open.
I was there on Sunday. The temporary entrance is fine. No worries about how difficult it would be to find your way
Yes, but the temporary entrance is pretty easy to navigate
I was there two weeks ago. There is construction near the entrance, but it does not interfere with people coming or going nor does it prevent seeing any of the exhibits.
I don't know! My last visit was April of this year!1 I doubt that they close the exhibits in order to work on the entrance! Having said that, it is probably a good idea to call them and find out. It might save you some money and frustration. .😎
Not at the entrance but there is some construction on the grounds.
