Massachusetts lawmakers have taken a significant step towards enhancing the state's infrastructure with the passage of House Bill 4307, aimed at financing long-term improvements to municipal roads and bridges. This landmark legislation, commonly referred to as the Chapter 90 bill, proposes approximately $1.2 billion in bonding to support critical transportation projects across the Commonwealth.

During the formal session on July 23, 2025, Representative Arciero of Westford highlighted the bill's potential to promote regional equity and address local transportation needs. The funding will provide a 50% increase over historical levels, with $300 million allocated for the Chapter 90 program alone. This funding will be distributed to municipalities based on a formula that considers road mileage, population, and employment, ensuring that all areas, including rural communities, receive necessary support.

The bill also includes $885 million for three key programs designed to bolster the state's transportation infrastructure. This includes $500 million for a life cycle asset management program targeting the worst condition roads, $200 million for repairing local culverts and small bridges, and $185 million for various capital projects aimed at reducing congestion and improving safety.

The funding is made possible by the recent strategic increase in appropriations to the Commonwealth Transportation Fund, which has expanded the state's borrowing capacity. This proactive financial management is expected to provide municipalities with much-needed stability during uncertain fiscal times.

In addition to addressing immediate infrastructure needs, the legislation reflects a commitment to responsible governance and fiscal health. Lawmakers emphasized the importance of maintaining strong credit ratings and managing debt effectively, ensuring that future generations inherit a robust infrastructure system.

As the bill moves forward, it signals a strong commitment from the Massachusetts Legislature to invest in the state's transportation future, enhancing safety and accessibility for all residents.
