Instead of funding many of the existing projects that depend on federal money — a practice that officials say they worry is wasteful — the administration says it wants to move toward a version of financing projects that is based far more on private funding. ... Capitol Hill aides closely tracking infrastructure funding say that uncertainty over the administration’s infrastructure plans is particularly threatening to programs that are far along and are dependent on federal funding for completion.

The projects that are most at risk, they said, include some that have moved through the funding pipeline for years but are just short of final approval. Many are in states that Trump won last year, and they include a light-rail ­platform-lengthening project in Texas, a streetcar line in Arizona, and a bus rapid-transit line in Indiana.


So far, Trump’s advisers have publicly identified projects to cut at a faster pace than they’ve identified projects to fund, leading to widespread confusion about the administration’s intent.

Dan Slane, an Ohio developer who worked on the infrastructure plan during Trump’s transition, said he is still receiving calls from state and local governments, frustrated with the slow pace of planning and asking him for details.

“They don’t want to pay for anything,” Slane said of the administration. “They want all infrastructure to be privately financed or privately owned.”

White House officials say they are taking their time because they want to create more accountability for how money is spent.
