Can Interstate Tolling Save U.S. Roads?

America’s Interstate highways are reaching the end of their 50-year design life, and will all need to be reconstructed over the next several decades. The estimated cost of reconstruction and prudent widening is nearly $1 trillion — and no funding source exists for this purpose.

The U.S. has a tolling pilot program, but all the slots are currently used. To allow other states to rebuild their Interstates through tolling, expand the three-state Interstate System Reconstruction and Rehabilitation Pilot Program to all 50 states and allow participating states to use it to reconstruct all Interstate highways in their states, not just one. To ensure the support of highway users, provide stronger protections to ensure that the tolls are pure user fees that can be used only for the capital and operating costs of the rebuilt rural and urban Interstates. These protections should include:

– Statutory limitation on use of the toll revenues to the rural and urban Interstates only;
– Beginning tolling only after an Interstate segment has been rebuilt;
– Requiring that tolling be all electronic and interoperable nationwide;
– And granting rebates of state fuel taxes to Interstate toll-payers for the miles driven on the newly tolled and rebuilt Interstates.

Since there is no identified source of funding for the $1 trillion cost of Interstate reconstruction, a major benefit of this change is to provide such a funding source, available to states that comply with the user-friendly provisions. Since a per-mile toll is a mileage-based user fee, if all 50 states opted in, that would convert 25 percent of all vehicle-miles of travel to mileage-based user fees, an important first step toward replacing per-gallon fuel taxes. If the toll rates were limited to covering the capital and operating costs of the rebuilt system, highway users would pay somewhat more than they do now to use the Interstates, but would receive much better services.
