OKLAHOMA CITY, OK -- The Oklahoma City National Memorial Museum may not re-open until February 1.
This comes after a mechanical malfunction this week caused water to pour through the museum.
The leak started in equipment on the roof.
Museum officials say no artifacts were lost, but about a third of the museum's space were damaged.
Contractors have brought in more than 20 industrial dehumidifiers and fans and pulled up carpeting to speed the drying process.
Electrical and air conditioning work is also being taken care of.
