With time running out, a White House official says the Obama administration will intensify its efforts to get Congress to pass legislation that pays for roads and bridge repair.
The Highway Transportation Fund is set to run out of money in August unless lawmakers act to renew it. The money comes from a tax on gasoline sales.
President Barack Obama unveiled a funding proposal earlier this year. A bipartisan group of senators is also preparing a proposal of its own.
The infrastructure push includes Obama speaking Wednesday in front of New York's Tappan Zee Bridge to call on Congress to act.
The official was not authorized to discuss the plans by name and spoke on condition of anonymity.
