Only two Twins games at the Metrodome were ever postponed. The first was on April 14, 1983, when a massive snowstorm prevented the California Angels from getting to Minneapolis. The game would have likely been postponed in any case, however; that night heavy snow caused part of the roof to collapse. The second was on August 2, 2007, the day after the I-35W Mississippi River bridge had collapsed a few blocks away from the Metrodome. The game scheduled for August 1 was played as scheduled (about one hour after the bridge had collapsed) because the team and police officials were concerned about too many fans departing Metrodome at one time, potentially causing conflict with rescue workers. The August 2 ceremonial groundbreaking at the eventual Target Field was also postponed, for the same reason. The Metrodome carried a memorial decal on the backstop wall for the remainder of the 2007 season.
