How does the United States pay for transportation infrastructure and improvements?

The major source of funding for federal highway and transit investment is the Highway Trust Fund. The fund receives revenues from gasoline and other motor fuel taxes and from taxes on heavy trucks and truck tires.

How does electronic toll collection work for drivers that don't have a transponder?

Some states have transitioned to electronic tolls and do not provide lanes for paying tolls by cash. Many states have installed license plate recognition systems for vehicles that do not have a transponder and thus are not equipped for electronic toll collection. This system records the vehicle's license plate as it passes through the toll and generates a bill based on the vehicle's registration information.

Why does highway or road construction take place during the day in some places and at night in other locations?

Highway and road construction schedules are based on a number of different factors, including the safety of workers and the public, the impact on motorists through the work zone, and the impact on area schools and hospitals.
