WASHINGTON – With large portions of the 46,000-mile Interstate Highway System wearing out and needing replacement, but with few federal and state dollars do it, one possible solution goes back to how most roads were originally built: tolls.
Fuel taxes aren’t keeping up with growing highway maintenance needs, forcing states and the federal government to look for alternatives and tolls are part of the mix.
The libertarian Reason Foundation released a study last week that proposes tolling the entire interstate system, charging 3.5 cents a mile for cars, and 14 cents a mile for trucks, adjusted every year for inflation.
Under federal law, new interstates can be tolled, but existing ones can’t, and Congress would have to change it. But it could be a tough sell to a public long accustomed to freeways.
“Tolling is not something that many motorists want,” said Michael Green, a spokesman for AAA. “They feel, in their mind, that they’ve already paid for those roads.”
In some ways, they did. Starting in the 1950s, the highway trust fund was established to fund interstate construction with revenue from the federal gasoline tax, which all motorists paid every time they filled their tanks.
Now, the oldest parts of the system are at the end of their design life, and the tank is almost dry. Congress hasn’t raised the federal gasoline tax of 18.4 cents a gallon in 20 years, and the tax has lost a third of its value to inflation. People are driving less and cars get better mileage, further reducing revenue.
The International Bridge, Tunnel and Turnpike Association estimates that it would cost from $1.3 trillion to $2.5 trillion to rebuild the entire interstate system over the next 50 years. The highway trust fund has been steadily paying out more than it takes in. The Congressional Budget Office projects that it could go broke next year.
“The gas tax is clearly on its last legs,” said Bob Poole, director of transportation policy at the Reason Foundation and author of the tolling study.
