Disadvantaged Business Enterprise Supportive Services Expansion Act

This bill increases funding for programs supporting small businesses owned by socially and economically disadvantaged individuals in transportation contracting. It raises the Federal Highway Administration's program cap from $10 million to $25 million annually and establishes new $5 million annual programs for the Federal Transit Administration and Federal Aviation Administration. These programs provide training, assistance, and support to help disadvantaged business owners compete for government transportation contracts. The funding comes from existing transportation budgets and the Airport and Airways Trust Fund. The bill directly affects small businesses owned by socially and economically disadvantaged individuals seeking to participate in federal transportation projects.
