Wall collapses in subway station near WTC

A wall at a subway station abutting the World Trade Center site suddenly collapsed into a pile of rubble yesterday.

Cinder blocks fell on Cortlandt Street’s northbound R-train platform at 8:30 a.m., authorities said.

No injuries were reported, but subway service was slowed for nearly four hours.

MTA officials said they weren’t sure why the wall collapsed, but a maintenance worker at the scene said wet weather was likely a factor.

“It’s water damage,” he said. “It’s just old, and it’s raining.”

After workers placed plywood over the damaged wall as a temporary fix, an MTA official said the site is now “deemed safe.”
