City Sanitation Department spokesman Keith Mellis says 149 workers converged on Times Square as New Year's Eve celebration ended early Sunday.
They used 22 trucks, 24 mechanical sweepers and 37 backpack blowers to clear an estimated 40 to 50 tons of confetti, party hats and other remainders of the revelry.
Mellis says Times Square reopened to traffic at 6 a.m.
Sanitation workers are still there tidying up remaining bits debris, such as confetti that is belatedly wafting to the ground from widowsills and rooftops.
