U.S. Transportation Secretary Ray LaHood has announced the fourth round of the TIGER (Transportation Investment Generating Economic Recovery) grant program.

$500m is available in the 2012 TIGER scheme for transportation projects.

Projects including high speed rail lines and intercity passenger rail projects are eligible for funding.

“President Obama made clear in his State of the Union address that investing in transportation means putting people back to work, and that’s just what our TIGER program is doing in communities across the country,” said Secretary LaHood.

“Americans are demanding investments in highways, ports, commuter rail, streetcars, buses, and high speed rail. These kinds of projects not only mean a stronger economic future for the U.S., but jobs for Americans today.”
