A Brooklyn councilman is calling on the MTA to drop its “exorbitant” $15 toll to drive into Staten Island — at least for a day — to celebrate the Verrazano-Narrows Bridge’s upcoming 50th anniversary.

Vincent Gentile, who represents Bay Ridge on the Brooklyn side of the Verrazano, has asked the MTA to let drivers pass over the bridge for free on Nov. 21 in honor of the semicentennial.

“Or at the very least, roll the toll back to 50 cents,” which was the price when the 2½-mile bridge opened in 1964, Gentile told The Post.

“It would be the right thing for the MTA to do, considering all the money motorists have put into the bridge in tolls for decades,” Gentile said. “And it would really be the greatest way to celebrate the 50th anniversary.”

MTA spokeswoman Judie Glave said the agency is “glad the councilman is excited about the anniversary.”

But she claimed, “There’s no precedent for reducing or rolling back the tolls because we are legally prevented from doing so.”

Glave said a state-bond requirement mandates that the full toll is collected.

The MTA averages about $1 million in Verrazano toll revenue daily.
