On May 14, 2003, the Administration transmitted the Safe, Accountable, Flexible, and Efficient Transportation Equity Act of 2003 (SAFETEA) to the Congress for consideration.[27] This legislation included several proposals that would encourage the formation of public-private partnerships. Subsequently, both the House of Representatives and the Senate introduced their own surface transportation reauthorization proposals.[28] These Congressional proposals included several concepts that were part of the Administration's SAFETEA proposal. At the time of this report, Congress was still considering these surface transportation reauthorization bills. These provisions are discussed in greater detail in Chapter VI, U.S. DOT Recommendations.
