A City Council panel on Tuesday green-lit a bill that would require city facilities to receive deliveries at night in an effort to reduce traffic congestion.

The legislation passed by the transportation committee, which will go before the full Council Wednesday, would mandate the city to create a plan for deliveries in Manhattan below 60th Street and in two other yet-to-be-determined “highly congested areas” to take place between 7 p.m. and 6 a.m. “where feasible.”

Manhattan traffic speeds have cratered in recent years, a trend that has shown little sign of letting up.

To help tackle the problem, the city has already started an off-hours delivery program, which offered businesses incentives to receive goods at night.

“We’ve all been on a congested city street… because of a truck parked delivering goods,” said bill sponsor Councilman Costa Constantinides (D-Queens). “There are instances when the city is making that more complicated.”

Testifying on the bill last October, city transportation officials indicated there might be “challenges” that prevent off-hour deliveries at certain facilities.

Constantinides said buildings without sufficient staffing or near residences may need to be exempted from whatever plan city officials design.

“It’s really about evaluating city facilities for the possibility of implementing what I believe is going to be a real congestion reliever,” he told the Post. “We’ve asked businesses to do it. We’re not putting our money where our mouth.”
