Revel is back in business.

Full financing for the half-built, long-stalled Revel Casino in Atlantic City closed yesterday, a source told The Post.

“It finally made it across the finish line,” the source said.

With the $1 billion-plus money in place, construction workers are expected to soon return to the site — a much-needed shot of good news for the embattled city and cash-strapped state. The plan is for the 53-story casino to open in summer 2012, the source said.

In recent weeks, New Jersey Gov. Chris Christie leaned on executives at Morgan Stanley, which owns the Revel, to try again to raise the cash needed to complete the project. Efforts last year to raise the needed funds to get the casino built failed.

The developer, Revel Entertainment Group, hired JPMorgan Chase last month to raise $1.15 billion.
