"We got this far by the hard work and discipline. We gotta stick to it so we can get to the next phase," says New York City Mayor Bill de Blasio.

NEW YORK, June 8  -- After nearly three months of lockdown, New York City entered the first phase of reopening on Monday, 100 days since the city reported its first COVID-19 case.

"This is a powerful day," said New York City Mayor Bill de Blasio on Monday morning at a press briefing in Brooklyn. "It is the day that we start to liberate ourselves from this disease."

The mayor thanked New Yorkers for their cooperation in the battle against the coronavirus, urging people to remember the lessons while going forward.

"We got this far by the hard work and discipline. We gotta stick to it so we can get to the next phase," he said.

According to the phased reopening strategy designed by the New York state government, businesses permitted to reopen in phase one include construction, manufacturing, wholesale and curbside and in-store pick-ups for nonessential retail.

The mayor said last week that more than 30,000 construction sites will reopen during the first phase, and up to 400,000 non-essential workers in various sectors including construction, manufacturing, wholesale and curbside retail would go back to work.
