BROOKVILLE, Pa., Aug. 23 - Anthony Foote spends a lot of time driving his Kenworth T-600 truck on Interstate 80 in Pennsylvania. He prefers it to the state's other east-west highway, the Interstate 76 turnpike, which can cost him $140 in tolls.

So the news that the state plans to impose tolls on I-80 was as upsetting to Mr. Foote as finding an ugly scratch in the purple paint on his rig.

"I hate paying tolls," he said. "It eats up my profit. If this goes through, you'll have a lot of truckers avoiding Pennsylvania - including me."

Pennsylvania officials plan to build up to 10 toll areas along the 311-mile stretch of Interstate 80 in the next three years to help pay for road, bridge and mass transit projects and subsidies.

The move has sparked a political war between the bipartisan coalition of state legislators who approved the plan and two Republican congressmen who say it is a "shell game," taking revenue from rural Pennsylvania to bail out the state's urban areas.

"It's absolutely horrendous for my district," said one of them, Representative John E. Peterson, whose Fifth Congressional District covers about half of I-80 in north central Pennsylvania. "Every major bill like this should be measured by whether this will make people less likely to come here. And if this stays active, we'll never get another distribution center or similar business again in my district."

Paying for new roads with tolls, or adding tolls to sections of older urban roads, is common across the country. But experts say that imposing tolls on an entire interstate highway that had been free may be unprecedented, in part because the federal government typically bans tolls on highways paid for with federal money, as I-80 was.

Imagine the new slogan on license plates: "Pennsylvania, Land of Tolls."

The state legislature is increasingly enchanted by the notion of converting free interstates into toll roads as a way to raise money for highway maintenance and mass transit operations.

When the state House reconvenes Monday to tackle transportation funding, there are likely to be new calls for new toll roads. I-80 across northern Pennsylvania. I-81 in eastern Pennsylvania. I-79 in western Pennsylvania. Even Philadelphia's two main interstates, the Schuylkill Expressway (I-76) and I-95.

But there are serious federal barriers to widespread tolling on existing interstates that could burst the bubble in Harrisburg.
