Controlled Blasts to Bring Down Cranes at Collapse Site Associated Press NEW ORLEANS - Two giant, badly damaged construction cranes towering over a partially collapsed hotel project are to be demolished Friday with a series of controlled explosions in hopes of dropping them straight down without damaging nearby businesses and historic buildings around the site at the edge of the French Quarter. Fire Chief Tim McConnell said work was beginning Thursday in hopes of bringing the multi-ton structures down ahead of approaching tropical weather. Forecasters said a tropical storm could form in the Gulf of Mexico and affect the area by Friday night. At a news conference, authorities said the storm was expected to move east of the city, but could still kick up stiffer winds and rain that might contribute to the cranes tumbling in dangerous directions. .
