President Obama once again used a State of the Union address to highlight the need for transportation infrastructure investment January 20, telling members of Congress and the nation that, “twenty-first century businesses need 21st century infrastructure—modern ports, stronger bridges, faster trains and the fastest Internet.  Democrats and Republicans used to agree on this.”  In addition to the President’s remarks, the U.S. Conference of Mayors was in the Nation’s Capital this week for its annual winter meetings and transportation infrastructure investment was high on the meeting’s agenda.  The mayors heard from Vice President Biden, U.S. Transportation Secretary Anthony Foxx and House Transportation & Infrastructure Committee Chairman Bill Shuster (R-Pa.) about the importance of federal transportation investment.  The mayors also released a national public opinion poll on voter attitudes and priorities that found—among other things—55 percent of respondents believe “a new transportation investment bill that targets renewal, repair and modernization of the nation’s infrastructure” is a high priority for Congress.
