During his presidential campaign, Trump said he would push for a $1 trillion infrastructure program to rebuild roads, bridges, airports and other public works projects, but he has not presented a specific plan.

White House spokesman Sean Spicer said "strong public-private partnerships" would be key to rebuilding the nation's roads, bridges and airports.

"Infrastructure used to be a point of American pride, but now an overbearing, ineffective regulatory system can keep projects in limbo for years," Spicer said. "The government has wasted too much of the taxpayers' money on inefficient and misguided projects."

The White House sees infrastructure as a potential large job creator but officials have said the federal government cannot shoulder the entire burden. The administration is looking at toll roads, tax credits and other ways to spur private investment.
