The main purpose of this legislation, known as the "Saving Transit Art Resources Act" or the "STAR Act," is to enable the use of certain federal funds for the costs associated with incorporating art into transportation facilities. This aims to enhance the aesthetic and cultural value of public transit spaces. Key provisions of the STAR Act include changes to existing laws that govern how federal funds can be allocated for transportation projects. Specifically, it allows for the incremental costs of adding art to facilities to be covered by these funds.
