Billionaire Donald Trump has fame, fortune, and a hit TV show, but Congress wants to give him a little more: $2.5 million to pave the way for better views from his big West Side towers project.

The $284 billion highway spending bill passed overwhelmingly last week by the House includes a provision for some $2.5 million in road construction that would boost Trump’s long-held goal of burying part of the West Side Highway near West 61st Street.

Burying that section would add park space and provide better views from Trump Place, a group of towers looking over the Hudson River.

Trump’s hope of lowering the West Side Highway has been a political sore point for years, in part because Rep. Jerrold Nadler, in whose district the project lies, opposes the plan to tear down and bury the elevated highway.

Mr. Nadler, a Manhattan Democrat, openly fought with Rep. Sue Kelly, a Republican of Katonah, in 1998 over a similar $6 million provision for construction at the site. It is unusual for members of Congress to push for spending outside their own district.

Keith Ashdown, vice president of Taxpayers for Common Sense, a watchdog group, blasted the funding.

“There’s probably a very short list of individuals who don’t deserve to get any federal money, and I would put Donald Trump at the top of that list,” said Mr. Ashdown, who also complained that no lawmaker has been willing to take credit for the measure.

“Nobody knows for sure who put this in the bill behind closed doors in the dead of night, so Donald Trump’s getting a check for $2.5 million and nobody’s even saying who did that.”

The Senate plans to take up the massive six-year construction spending bill this week.
