WOODBRIDGE -- Hurricane Sandy's descent on the region last month cost the New Jersey Turnpike Authority an estimated $15.4 million, officials said Tuesday.

Of that amount $6.5 million accounts for cleanup costs for which the authority should be reimbursed by the Federal Emergency Management Agency; the remaining $8.9 million accounts for the estimated loss in toll revenue on the New Jersey Turnpike and the Garden State Parkway in the last four days of October.

"Unfortunately, FEMA does not reimburse revenue loss," NJTA Executive Director Ronnie Hakim said during a board meeting Tuesday. "Really, it's a $9 million hit we took in just those few days. Hopefully winter will be milder. Those are real revenue dollars we will not get back from FEMA."

Financial reports show that Turnpike tolls accounted for $6.5 million of the lost revenue, and Parkway tolls accounted for $2.4 million.
