Despite talks of spending big on infrastructure, the Trump administration and congressional leaders look to be less likely to pass a large infrastructure bill in 2017 and focus instead on a more incremental approach to spur public-private partnerships (P3s). This may be done through loosening environmental reviews, removing other red tape and possibly approving new tax credits.
Some Republican congressional leaders, such as Paul Ryan, seem open to using tax credits to spur private infrastructure work; however, it is not clear how Congress would pay for those tax breaks or how they would select projects deserving of special treatment.
