Oliver bath house closed?

Hi all, I tried to go to Oliver bath house yesterday (Tuesday) around 5 PM, but the doors were locked and the sidewalk was closed in front of the building. I could see ladders in the vestibule through the front doors. I haven't been able to find anything on their website or social media. I even called and left a message at the cityparks aquatics department, but haven't received a call back. They were supposed to be open from two till seven for open swim. Does anybody know what's going on?
