If you were planning to visit the archaeology wing at the Israel Museum in, oh, the next 2-3 years, you’re going to be disappointed. According to the museum’s website, the wing “is currently closed for comprehensive renewal and will reopen to the public in 2009-2010.” It really is a shame that they cannot renovate a section at a time, so that a portion of the exhibits are open to the public. Or create a temporary exhibit of the most important finds. Until then, the public can visit the lousy Rockefeller Museum (some great finds, but poorly displayed and described), the Eretz Israel Museum in Tel Aviv, or the Hecht Museum in Haifa.
Safe prediction: the museum wing will not finished when they say.
