Truck driver Joe Macken built a big model of New York City.

He worked on it for over 20 years.

He used his free time.

He made it from balsa wood and foam board.

His daughter told him to show it on TikTok.

It was in his basement.

The model has over 800,000 buildings.

The videos became very popular.

They got more than 10 million views in one week.

The Museum of the City of New York saw the videos.

Then they called him.

His model is now in a show.

The show is called "He Built This City."

It opened in February near Central Park.

It runs until Oct. 12.

Macken said he never thought about finishing it.

He had so much fun building it.

The model covers all five boroughs.

It also covers parts of New Jersey and Long Island.

It sits on more than 300 big foam boards.

The boards connect like puzzle pieces.

It is 50 feet long.

It is almost 30 feet wide.

Each inch shows about 160 feet.

Most buildings are made of light balsa wood.

They include Manhattan skyscrapers and small homes in Queens.

Macken is from Queens.

A school trip inspired him.

He saw the Panorama of the City of New York.

It is at the Queens Museum.

He started building in his 40s.

His family moved from Long Island to the Albany area.

He said he might have missed New York.

The model is not an exact copy of today's city.

Macken kept some old landmarks for himself.

They include the twin towers and the old Kosciuszko Bridge.
