Sports fans will be “on top of the action’’ as never before at the newly renovated Madison Square Garden.

These never-before-seen photos show the centerpiece of the arena’s renovation — two revolutionary glass-walled seating “bridges” attached to the roof that hold 430 seats, each going for $110 to $210.

The bridges include walkways behind the seats for fans to stroll along. The bridges can hold a total of 900 people.

“[People] will be on top of the action as well as very close to it. There is nothing like this in the world,” said architect Murray Beynon, who headed the three-year project.

“It gets people right out there. These are the most unique seats in a sports arena anywhere in the world.”

A limited number of tickets for seats on the Chase Bridges are still available.

The bridge seats are 94 feet away from the arena floor — about the same distance as existing front-row seats.

The Garden has been shutting down for four to five months every year for the past three years to finish the billion-dollar renovation, which also includes wider concourses, mores suites and comfortable new balcony seating.

It reopens on Oct. 25 for a Knicks preseason game.

The north bridge has 355 seats and the south bridge 75, plus space for media.

The bridges are meant to resemble the suspension bridges that connect Manhattan to the mainland and outer boroughs, Beynon said.

One of the project’s biggest challenges was integrating the bridge with the stadium’s distinct curved interior, Beynon said.

He also had to navigate tricky technical issues.

“Fans will be jumping up and down when their teams win. But the bridges need to be vibration-free and comfortable,” he said.

“That was an incredible engineering feat,” he said.
