The start date for the upcoming U2 world tour has been pushed back by at least a couple of weeks, sources tell Billboard.biz. The new date and location have yet to be determined.

The tour, which was first tipped on Billboard.biz, was initially slated to start March 1 in Florida. The source says the outing has been delayed due to routing issues; U2 manager Paul McGuinness confirms this on the band's Web site.

The tour, in support of "How to Dismantle an Atomic Bomb" (Interscope), will be promoted by Clear Channel Entertainment's TNA International, headed by president Arthur Fogel.

The band still plans to play approximately 35 shows in U.S. arenas in the spring, then head to Europe for 30 stadium shows, back to the U.S. for another 35-date arena swing, and then Japan and Australia.

U2's last tour, in 2001, was also promoted by Fogel and grossed $104 million from 106 shows worldwide, according to Billboard Boxscore.
