Gov. Cuomo says he may nix the HOV lanes on the Long Island Expressway — by turning them into bus lanes — to help move commuters who will be displaced by repairs at Penn Station.

The governor has predicted that the planned repairs at Penn will cause a loss of about 20 percent of Long Island Rail Road trains from there this summer, leaving hoards of commuters looking for a different way to and from the city.

Cuomo said Monday that he may push to have the LIE’s HOV lanes given over to buses or at least raise the number of people who have to be in a car for it to qualify for the express lane. The current minimum is two people, including the driver. There is one HOV lane in each direction of the highway.

There also would have to be new park-and-ride lots “because people need to get in from Long Island, and the congestion is already horrendous,” Cuomo told WCNY’s “Capitol Pressroom’’ radio show.

He again urged President Trump to make Penn Station the top priority for the $1 trillion infrastructure plan that Trump said he wants to implement.

“If you’re looking for one infrastructure plan, this should be it,” Cuomo said, adding that the “smart way to do it” would be to rebuild Penn as part of the Farley Post Office/Moynihan Station renovations and build a new Gateway Tunnel to New Jersey as a single project.

“You could have a world-class transportation system, and if the president gets one project, I would nominate this project,” he said.

Cuomo sent a letter to President Trump on Sunday saying he’s open to all options for heading off a disaster that the governor says would affect as many people as Hurricane Sandy.

“You reduce train service by 20 percent into Penn, you’re going to overstress the entire system,” he explained. “There will be a ripple effect that will be a tidal wave.”

The governor said the planned six-week shut-down of Penn is likely to last longer and have huge widespread impacts on other transportation systems.

“The subway system that is already overstressed will now have to absorb more people,” he said. “The Long Island Expressway will look like a parking lot, and I don’t believe its going to take six weeks. If you look at the track record with Amtrak, they almost always take longer than they say they’re going to take.”

Cuomo is also considering a high-speed ferry service between Long Island and New York City.

Meanwhile, a bipartisan group of United States congressional delegates stepped up to join the governor’s call for a federal bailout.

“We can no longer delay if we expect Penn Station to operate any differently ten years from now than it did thirty years ago,” the congressional delegation said in a statement. “The current dysfunction has put a sharp focus on the chronic issues plaguing our already stretched, overburdened and historically underfunded transportation infrastructure and the ripple effect it creates all along the Northeast Corridor.”

A few politicans have also called for Amtrak to cede control of Penn Stations to either the Port Authority or the MTA. But some are skeptical that either the Port Authority or the MTA have the resources to adequately steward Penn Station.

“The Port Authority has a very full plate of projects, so I’m not sure how much more they can take on,” said MTA board member Veronica Vanderpool. “The MTA also has a very full plate of projects.”

The state Senate is moving to try to withhold funding for Penn Station until the problems are corrected. Cuomo said he understands the tactic and the frustration.

“Between the Long Island Railroad and New Jersey Transit, we pay about $150 million a year rent to Amtrak,” Cuomo said. “ “So, the point is: Why the heck are we paying rental payments when the ceiling is collapsing and really these are deplorable deplorable conditions? I think that’s what the Senate is trying to get at and the intent is right. Sometimes pieces of legislation are more about the statement than the specifics.”
