MTA Spent $250 Million Terror-Proofing Tunnels And Bridges

The MTA is nearing completion on a $250 million anti-terror project to reinforce underwater subway tunnels and bridges against a bomb blast, The Post has learned.

Since 2004, agency contractors have been lining subway tubes -- especially the 10 that run under the East River -- with high-impact-bearing metal that would prevent collapse or massive flooding in the case of a terrorist attack, multiple sources said.
