Negating Neighborhood Noise Act of 2024

This bill modifies federal highway funding rules to allow the use of Highway Trust Fund money for constructing specific noise barriers near highways. It permits Type II noise barriers (designed to reduce highway noise) if they separate highways from older residential areas (at least 10 years old) or meet other defined criteria, while generally restricting such funding otherwise. The bill also enables "multipurpose" noise barriers that can host renewable energy or broadband infrastructure, and requires project sponsors to consider aesthetics when building these barriers. It directly affects highway construction projects near residential neighborhoods and state transportation agencies managing federal highway funds.
