New York Today: Skyward

This morning, Mayor Bloomberg will cut a ribbon and declare 4 World Trade Center open for business.

It’s the first tower completed on the original World Trade Center site â€" a big step forward in the long rebirth at ground zero.

It was produced by two Times reporters, David Dunlap and Stephen Farrell, who toured the building the other day.

Four World Trade Center is not to be confused with One World Trade Center, which, at 1,776 feet, was declared the nation’s tallest building on Tuesday.

Still, Four World Trade Center is nearly 1,000 feet high.

And from the inside, it’s pretty spectacular.

On the upper floors, there are no columns in the middle, so the space is wide open.

“When you step out onto a floor, with an 80-foot-wide prospect of the harbor, your socks are knocked off,” Mr. Dunlap told us.

The building, which will be home to the Port Authority and city offices, must strike a balance between commerce and commemoration.

Its lobby faces the Sept. 11 Memorial, Mr. Dunlap noted.

Here’s what else you need to know for Wednesday.

WEATHER

Bone-chilling. A high of 39, but with stiff winds, making it feel like it’s in the teens or low 20s.

The good news: temperatures should hit 60 over the weekend.
