BOSTON (AP) — Massachusetts House leaders began debate Wednesday on a proposed $57.9 billion state budget for the 2025 fiscal year that would include $500 million for the state’s emergency shelter system and what lawmakers say is a record investment of $555 million for the beleaguered Massachusetts Bay Transportation Authority.

The $500 million for emergency shelters is about half of what Democratic Gov. Maura Healey said is likely needed for the program, which is straining in part because of an influx of migrants seeking shelter.

Democratic House Speaker Ronald Mariano has said the $555 million investment in the MBTA — and another $184 million for regional transit authorities across the state — is key to the state’s economy.

Mariano said the proposed funding would represent a 41% increase in transportation funding from the current fiscal year.
