Shea Stadium is officially history.

The last standing structural portion of the 44-year-old stadium came crashing to the ground yesterday at 11:22 a.m., a process that took less than 30 seconds and resulted in a considerable cloud of dust.

A handful of Mets fans who watched from outside the surrounding fence in 30-degree weather cheered as the four levels of ramps that used to wind behind Section 5 were pulled down.

As the dust cleared, the fans briefly chanted "Let's Go Mets" and construction workers hugged, clapped and pumped their fists.
