Transportation projects funded by the $787 billion U.S. economic stimulus package will lead to an "enormous number" of jobs within months, Transportation Secretary Ray LaHood said.

"You're going to see an enormous number of people in the states working this spring, summer and fall in good-paying jobs," LaHood said in an interview with Bloomberg News.

The $28 billion in stimulus money for highway construction will create employment quickly because state transportation departments will distribute it to projects that await only funding to get started, LaHood said. Stimulus money worth $8.4 billion for mass transit and $8 billion for high-speed rail will also be distributed quickly, LaHood said.

President Barack Obama signed the economic stimulus package into law last month as the U.S. began the second year of the worst economic slump since the Great Depression. The administration is trying to stem job losses, which have accelerated this year.
