After a month containing nearly 2400 controlled explosions, blasting has wrapped underneath Grand Central as part of the East Side Access work, the MTA announced today. According to the agency, crews blasted out 857,000 cubic yards of muck from the future LIRR terminal. It’s enough debris to cover the entirety of Central Park one foot deep.
“This is a very significant milestone for the East Side Access project,” Michael Horodniceanu, President of MTA Capital Construction, said. “The caverns are essentially now fully excavated. Much work remains to be done to build the platforms and tracks, and finish what is currently raw, cave-like space. But we now have a fully built shell in which all future work will take place.”
As part of the milestone announcement, the MTA released the video I’ve embedded above showing blasting and progress at the site. The East Side Access project is expected to wrap up eventually this decade.
