NEW YORK — The easing of some coronavirus restrictions Wednesday on Long Island left New York City as the only part of the hardest-hit U.S. state that has yet to begin the process of reopening the economy.

The sprawling suburbs of Nassau and Suffolk counties, where the virus has killed at least 4,000 people, won approval Tuesday from Gov. Andrew Cuomo to gradually restart construction, manufacturing, agriculture and retail activity two months after nonessential business ceased.

The Democratic governor also lobbied President Donald Trump in Washington for help with massive New York City transportation projects — including train tunnels, a subway expansion and an airport rail link — and accused top Republicans who oppose more aid of “abusing” states, such as New York, that suffered heavy coronavirus losses.

The projects require some federal funding or approval. Cuomo said he and the Republican president, who are often at odds, will talk again next week.
