The plan announced Friday envisions design and construction savings that would reduce the new tunnel’s estimated cost from just over $11 billion to $9.5 billion. Repairing the existing century-old tunnel that was damaged in 2012’s Superstorm Sandy, and is a source of frequent delays due to crumbling infrastructure, would cost about $1.8 billion, or about $200 million more than previous estimates. The net cost decrease means the states will seek $5.4 billion from a federal grant program instead of $6.8 billion, project officials said in an email Friday.
