The main purpose of this legislation, known as the Small Projects Expedited Execution and Delivery Act or the SPEED Act, is to streamline the approval process for certain infrastructure projects that receive limited federal funding. The aim is to make it easier and faster to execute smaller projects that can benefit communities without the lengthy reviews typically required for larger projects. Key provisions of the SPEED Act include changes to the financial thresholds for what qualifies as a "categorical exclusion" under the existing law known as MAP-21.
