Sens. Sherrod Brown, D-Ohio, and Bob Casey, D-Pa., are also strong supporters.
Rahall, the top Democrat on the House Transportation Committee, said, "Committee Democrats insisted on closing the loopholes in our 'Buy America' laws to prevent the continuation of this outrageous and economically harmful practice of outsourcing our federal highway and transit construction."
Last year, Democrats backed numerous provisions to increase "Buy America" requirements, but they were removed during legislative conference discussions between Democrats and Republicans.
"Today we are here to finish the job and ensure that all taxpayer-funded infrastructure investments support American jobs," Rahall said.
The new bill would strengthen existing "Buy America" requirements to ensure all steel, iron and manufactured goods used in highway, bridge, public transit, rail and aviation infrastructure projects are made in the U.S.
The bill would also increase domestic content requirements for railroad and aviation projects from 60 percent to 100 percent by fiscal year 2017.
A recent Northwestern University study revealed stronger Buy America requirements for buses and railroads alone would create nearly 13,000 additional jobs.
Giving away American jobs, Rahall said, "should be inexcusable in any instance, but it is unconscionable when millions of Americans are seeking employment."
The new bill would allow federal agencies to waive "Buy America" requirements if federal officials determine needed steel, iron or manufactured goods are not being produced in the U.S. in sufficient quantities.
"Buy America" requirements could also be waived if using goods produced in the U.S. would increase total project costs by more than 25 percent.
Other labor and business groups backing Rahall's bill include: the International Brotherhood of Teamsters, American Foundry Society, International Association of Machinists and Aerospace Workers, National Steel Bridge Alliance, Nucor Corp. and the AFL-CIO Transportation Trades Department.
