According to an article on Mouse Planet today written by David Koeing, Indiana Jones is slated for a rare, multi-month refurb beginning Sept. 4th and reopening Dec. 7th. This is confirmed on DL's website on the Indy page.Indiana Jones Adventure | Adventureland Attractions | Disneyland ParkIndiana Jones Adventure Closed for Refurbishment
From September 4, 2012 through December 7, 2012, the exciting Indiana Jones Adventure attraction will receive refurbishment attention. Come back at the end of 2012 for a thrilling journey through the legendary Temple of the Forbidden Eye.
It is not yet on the refurbishment calendar but is stated on the official page. According to MP, the ride will mostly be getting theme appropriate fall-protection enhancements that will be there before OSHA comes in and causes an immediate closure ie. Alice.This article also mentions that Big Thunder, which Al originally said would go down in September and has yet to appear on refurb calendar, is actually going to be going under for it's top to bottom refurb in January. Perhaps it was pushed back because of Indy, who knows...Among the most noticeable changes will be widening the bridge in the “big room” to accommodate a new car maneuver. “They want to eliminate the chance that vehicles will put guests in precarious situations if they stop there," said one cast member. "The zone afterwards is a notorious spot where vehicles get ‘lost.’”
There will also be a significant number of Disneyland president George Kalogridis’ pet fall-protection enhancements. Ever since Disney was forced to rush Alice in Wonderland through an emergency rehab/disfigurement, Kalogridis has insisted on cutting OSHA off at the pass and incorporating better, more naturally themed protection devices on other attractions, such as the less-noticeable, rustic-looking railings along the Matterhorn track.
Indy will also receive plenty of show work and rehabs of the breakroom—a very welcome makeover considering how infrequently this attraction goes down.The original article can be found on Mouse Planet's main page under "Indiana Jones Goes Under the Knife" or here Indiana Jones Goes Under the Knife (Mouse Tales' David Koenig) by David KoenigAlthough other online sources cite Big Thunder Mountain as next in line, that coaster’s top-to-bottom safety update/rebuild is not scheduled to begin until January.
