Lawmakers across the U.S. have approved new proposals this year to pay for transportation improvements, including tax hikes, vehicle fee increases and bond packages. Two-thirds of all states have stepped up highway funding over the past five years.

Lawmakers across the U.S. have approved new proposals this year to pay for transportation improvements, including tax hikes, vehicle fee increases and bond packages. Two-thirds of all states have stepped up highway funding over the past five years.

It's happening in both Democratic- and Republican-led states as their transportation departments strain to overcome backlogs deepened by the last recession. And lawmakers are acting regardless of promises from President Donald Trump for a $1 trillion national infrastructure program.

Some state officials doubt that Trump's plan will make much of a difference when it comes to repairing and replacing thousands of old bridges or repaving and widening miles of congested roads.
