President Obama signed the stimulus bill [PDF] into law, approving $48 billion for transportation projects, to include $27.5 billion for highway and bridge construction and repair, $8.4 billion for mass transit, and $9.3 billion for high-speed rail and Amtrak. $6 billion will go toward clean water projects and $4 billion is allocated for public housing improvements.

The compromise bill includes $46 billion for transportation projects such as highway and bridge construction, as well as mass transit.

The House-approved stimulus bill allocates $43 billion for transportation projects, including highway and bridge construction and repair; $31 billion for work on federal buildings; and $19 billion in water projects. Construction spending is expected to be some of the slowest in the package.

Obama has not explicitly mentioned his National Infrastructure Reinvestment Bank plan recently. His $825 economic stimulus package that Congress is debating this week, however, has allocated $85 billion to infrastructure -- most for highway and bridge construction.

In a speech in Ohio, the incoming president said: “We'll put nearly 400,000 people to work by repairing our infrastructure -- our crumbling roads, bridges and schools. And we'll build the new infrastructure we need to succeed in this new century, investing in science and technology, and laying down miles of new broadband lines so that businesses across our nation can compete with their counterparts around the world.”
