Obama's plan calls for major investment in the country's roads and bridges, said Cramer, and that's why stocks like Chicago Bridge & Iron (CBI) sound like the natural choice. That is, until investors realize that 55% of CBI's revenues come from the liquified natural gas industry and not from roads.

Cramer said investors need to steer clear of all infrastructure stocks with an energy focus, as these stocks need not only higher energy prices to succeed, but also tons of credit to finance their projects. Stocks like Shaw Group (SGR), which derives 56% of its revenues from fossil fuels and nuclear energy, and even Cramer favorite Foster Wheeler (FWLT), a stock which he owns for his charitable trust Action Alerts PLUS, should not be bought solely on the Obama news.

What should you own then? Cramer likes Martin Marietta [MLM] and Vulcan Materials [VMC] because they make asphalt, concrete and cement. Both companies get half their sales from U.S. roads and bridges construction. Look to pick up MLM in the mid $60s and VMC at $49 and below.

Caterpillar [CAT] and AECOM [ACM] got the nod as well. CAT’s got a great yield these days after taking such a beating, and 70% of ACM’s backlog comes from government-funded projects. Try to pick up some ACM below $20 a share.

One stock heavy in the road and bridges business that doesn’t work right now, though, is Granite Construction [GVA]. It will benefit from the Obama plan, but the share price has already moved too much, Cramer said. It’s just five points off its 52-week high, and the company’s performing poorly to boot.
