Breaking down the Infrastructure Investment and Jobs Act

This interactive feature offers a comprehensive public resource to study IIJA’s contents. We arranged IIJA’s programs by topics and sub-topics, the primary federal agency, and likely spending levels. We have also subdivided programs by formula or competitive status and whether or not the program is new. Our raw data is available for download here.

Explore the distribution of likely spending within various topics and sub-topics by clicking within regions of the chart. Hover over the chart for more information about a given topic or program. Note: The summary metrics and table below will change as you zoom in or out of the chart.
