authorizing the sale of toll credits to fund a newly established noise barrier construction fund for the design and construction of noise barrier projects.

SB 152 authorizes the sale of turnpike toll credits to create a dedicated "noise barrier construction fund" for the New Hampshire Department of Transportation (NHDOT) to design and build highway noise barriers meeting specific federal criteria. The fund would receive revenue from selling up to $10 million annually in toll credits, subject to federal match requirements and legislative approvals, with funds restricted solely for noise barrier projects. NHDOT must follow established guidelines for Type II noise barriers and consult affected communities on project eligibility. The bill's fiscal impact is indeterminable, as the Department of Transportation notes no existing market or federal authority for toll credit sales, making implementation uncertain.
