Brooklyn Borough President and mayoral hopeful Eric Adams took to the subways on Wednesday to urge New Yorkers to return to their old commutes and offices, which have been mostly empty since March.

“We need New York to work and that starts with dispelling the rumors loud and clear — our subways are safe,” the masked Adams said during an organized ride from Brooklyn Borough Hall to Midtown Manhattan.

“If people trust the subway, they will return to their offices and their employment environment,” he said.

“If we don’t get people, passengers, back flowing through the arteries, we are not going to have our city open and running in an effective way.”

Subway ridership plummeted in the initial months of the pandemic, and has been slow to return in light of claims that mass transit is a vector for the disease.

The MTA, however, insists that zero coronavirus clusters have been traced back to transit anywhere on the globe.

Experts in London, meanwhile, tested surfaces and air through that city’s subway and found no traces of the virus, the Evening Standard reported.

Adams called it a “myth” that transit is unsafe.

“As long as people are wearing the mask, limiting speaking or any other method that release particles, our trains and buses are well ventilated, public transit is relatively safe,” he said.

The Brooklyn Democrat is a leading contender in next year’s race to replace Mayor Bill de Blasio, who has yet to produce a plan promised in September to bring back the city’s 380,000 municipal workers.
