Arlington, VA has had this for years. The I-66 10-mile segment to DC is dynamic pricing with no limit. I've seen it over $40. And they can pick and choose who it applies to. That was in part due to a lawsuit. The federal and state governments made hollow promises to Arlington to get I-66 built, then did little about the resulting traffic mess and noise for decades.

"The issue arises from a 1977 agreement between then-U.S. Secretary of Transportation William T. Coleman Jr. and the state of Virginia. In the so-called Coleman Decision, Arlington agreed to drop its opposition to the construction of I-66 in exchange for certain promises, including a four-lane limit, sound barriers, and truck and car-pool restrictions."
