The reason why American highways don't charge fees is because the main funds for construction come from the government's financial expenditure. 1956, American president Eisenhower urged congress to pass the highway bill funded by the federal government, which established the development framework of the highway.

According to the bill, the interstate highway is funded by the federal government and the state government at a ratio of 9:/kloc-0:. Federal funds are provided by the Federal Highway Trust Fund. 87.6% of the funds come from motor vehicle fuel tax. Another part of the funds comes from sales tax and large vehicle use tax. Because trucks wear more roads, they levy more taxes. The bill also stipulates that the construction of interstate highways is linked to the income of the fund, and how much money is raised and how much work is completed is not done by borrowing.

So now more than 90% of highways in the United States are free, and only about 10% is charged, which is mainly used for highway maintenance. But many highways in the United States were built a long time ago, so most of them have potholes. Only some fees, taxes and trust funds can no longer meet the needs of long-distance highway reconstruction.

The reason why most highways in the United States do not charge fees is mainly supported by a large number of taxes. In fact, this is another disguised charge. Many people like to compare the free high-speed in the United States with that in China, but one thing can be said: it took many years for other countries to slowly complete the high-speed construction, while the high-speed construction cycle in China is only 30 years. By borrowing money to build roads first, the mileage of expressways has now become the first in the world. But the loan is used to build roads, and the principal and interest must be paid back. That's understandable. So charging is also a normal phenomenon.
