As President Joe Biden and the Republicans haggle over the real definition of infrastructure, some in the latter camp have raised the possibility of using public-private partnerships to pay for new projects. The government would get new roads and bridges funded by private companies, which would then collect a share of the "user fees" charged to people who drive on them.
