President Obama hosted a bipartisan group of mayors and governors at the White House Monday to promote his $50 billion infrastructure initiative. Obama urged lawmakers to approve his proposal to modernize the nation’s roads and railways.

President Obama: “Over the next six years, we will rebuild 150,000 miles of our roads — enough to circle the world six times. We will lay and maintain 4,000 miles of our railways — enough to stretch from coast to coast. And we will restore 150 miles of runways and advance a next generation air-traffic control system that reduces delays for the American people.”
