Hundreds of millions of dollars in federal transportation subsidies for Massachusetts could be eliminated under President-elect Donald Trump’s second administration, according to former Massachusetts Transportation Secretary Jim Aloisi.

“We should be concerned, but not panicked,” Aloisi said in an interview Tuesday with The Crimson.

Massachusetts won several federal grants thanks to the bipartisan 2021 infrastructure law signed by President Joe Biden. Aloisi pointed out that because of measures like the infrastructure bill, Trump’s second administration will oversee much larger one-time discretionary grants to states than his previous administration.

Between Cambridge and Boston, the Biden administration has allocated $335 million to support the Allston I-90 Multimodal Projectt and $472 million for the Gare du Nord drawbridge.

Thomas P. Glynn, who headed both the Massachusetts Bay Transportation Authority and the Massachusetts Port Authority, expressed the same concerns. In an interview, Glenn said the cuts are “likely” — especially since construction on the projects whose funding is in question has not yet begun.

These grants operate on a reimbursement basis, meaning that Massachusetts will only actually receive money from the federal government after the funds have been spent from the state’s own pocket to complete the work funded by the grant. That gives the Trump administration, which has repeatedly emphasized its intention to cut the federal budget, the opportunity to withdraw the funds.

The $1.2 billion North Station drawbridge, which the T hopes to replace, connects commuter rail lines across the Charles River between Boston and Cambridge.

The $1.9 billion multimodal project will realign the Massachusetts Turnpike to reconnect the neighborhood, while improving bus, bike and pedestrian transit and opening dozens of acres of Harvard-owned land to development. The $335 million in federal funding comes from the Reconnecting Communities and Neighborhoods program, which aims to alleviate highways cutting through neighborhoods.

Aloisi said the project’s more progressive goals don’t align with the Trump administration’s priorities.

“Anything that has to do with transportation justice, with transit and rail versus highways and bridges, that’s what worries me,” Aloisi said. “It’s just not their priority.”

A spokesperson for Trump’s transition team did not respond to a request for comment.

U.S. Transportation Secretary Pete Buttigieg ’04 also alluded to concerns about the future of funding for the I-90 project during a press conference. Harvard Institute of Politics Forum on November 13, emphasizing the need to take immediate action.

“Across the river, I’m really excited — we now have the funding,” Buttigieg said. “We’ve already concluded parts of this grant agreement, but if we could work at breakneck speed – breakneck speed – then this would happen in a few years, right?

The Department of Transportation also did not respond to a request for comment.

Losing federal funds is not a fight Massachusetts will fight, according to Director of Federal Funds and State Infrastructure Quentin A. Palfrey ’96.

“Since the start of the Healey-Driscoll administration, Massachusetts has provided nearly $9 billion in federal funding for critical transportation, climate and economic development projects through the bipartisan Infrastructure Act, the on Reducing Inflation and the CHIPS and Science Act,” Palfrey wrote. in a statement.

“We are working hard to ensure we receive every dollar and will continue to do everything we can to bring more federal funds back to the state,” he added.

Aloisi also warned that there is still no “legitimate cause for panic.”

It’s unclear how serious Trump is about slashing the federal budget, or whether he would end targeted transportation subsidies to do so. Potential reductions in transportation subsidies would also likely require the approval of Trump’s new nominee for transportation secretary — former Rep. Sean Duffy — who has not taken a public position on the Massachusetts plans.

In a statement, city spokesman Jeremy C. Warnick said the city “is prepared to address any policy changes that may arise with the new administration.”

“We are working hard to ensure existing grant applications are fully processed as soon as possible,” Warnick added.
