For the past two years the big development story around here has been all Kendall Yards, all the time. First came the cleanup, but only recently the dirt started moving for site prep and in a big way. Beginning last week, much of the 'former' basalt outcropping was systematically dismantled. To ease the task, a little TNT was used to get out some of the more stubborn stuff. The video above was taken from what appears to be the vantage point of the health building. Wait for the slo-mo replay at the end. Those Black Rock folks mean business.
