The portion of the bridge they blew up was basically the metal parts of the bridge that lead up to the edge of the water. There is a portion of the bridge over the water that they left intact for equipment movement and storage, but they needed the Alexandria land portion gone so that they can begin building the new span in earnest. The remaining parts over the water (if I understand correctly) they'll be gingerly dismantling and getting rid of as they go, hopefully recyclying and augmenting some of the foundation to reduce the amount of dredging and impact on the Potomac.
Meanwhile, back on land, they now have a big heap of twisted metal that they have to haul away. But it's all on land, so they don't have to go diving for it.
