The Bay State will spend upwards of $8 billion over the next ten years improving its roads, bridges and regional transportation services if a proposal announced by the governor Tuesday is passed by the legislature.

Gov. Maura Healey, speaking from Union Station in Worcester, said that the investment will be included as a supplement to her 2026 budget proposal, and will be possible without further tax raises.

The plan would represent the largest state investment into transportation in more than 20 years, according to the governor.

“This historic transportation proposal represents smart, forward-thinking fiscal management, and it will have an impact on people in all regions of our state. We’re going to invest billions of dollars to deliver better roads, less traffic, safer bridges and a transit system that works in every region,” Healey said.

The money would be used to close a gap in the MBTA’s budget and move the state forward on West-East Rail development, according to the governor.

The plan comes in answer to a recommendation provided by the final report from the Transportation Funding Task Force released to the governor and made public with the announcement.

According to the report, “the Task Force recognizes that there are immediate and urgent needs to stabilize the operating conditions of public transportation agencies around the state, including the MBTA, RTAs, and microtransit services, and to address acute municipal needs for infrastructure funding, collaboration, and technical assistance for significant local and regional challenges.”

Healey’s proposal would pay for the investment using $765 million in Fair Share amendment funds in fiscal 2026. According to the governor’s office, these funds would be used to “maximize Fair Share through borrowing to yield $5 billion over the next 10 years for capital investment bonds in rail, roads, bridges, Regional Transit Authorities and culverts.”

A further $687 million from the fiscal 2026 operating budget would be used to address the MBTA’s budget shortfall, a more than two-fold increase on the $314 million included in Healey’s fiscal 2025 budget.
