Judge Steven Rhodes announced his decision from the bench.
"The court confirms the plan," Rhodes said.
Detroit is cutting the pensions of general retirees by 4.5 per cent, erasing USD 7 billion of debt and promising to spend USD 1.7 billion to demolish scores of dead buildings, improve public safety and upgrade basic services, among other key steps.
The case concluded in just under 16 months, lightning speed by bankruptcy standards.
No significant critics were left by early October. Bond insurers with more than USD 1 billion at stake repeatedly argued for the sale of valuable art but dropped that plea and settled for much less.
It took more than two years for a smaller city, Stockton, California, to get out of bankruptcy.
San Bernardino, a California city smaller than Stockton, still is operating under Chapter 9 protection more than two years after filing.
The most unusual feature of the plan is an USD 816 million pot of money funded by the state, foundations, philanthropists and The Detroit Institute of Arts.
The money will patch holes in Detroit's pension funds, prevent even deeper cuts to retirees and avert the sale of city-owned art at the world-class museum.
