* “Interstate System Reconstruction & Rehabilitation Pilot Program” allows the tolling of existing interstate highways, bridges, and tunnels to fund repair of existing highways.
* “Interstate System Construction Toll Pilot Program” authorizes tolling existing facilities on the interstate system to fund new interstate highways.
* “Value Pricing Pilot (VPP) Program” allows new tolls on existing toll free facilities such as high occupancy vehicle (HOV) lanes, tolls on new lanes added to existing highways, and electronically collected variable tolls on existing and new toll facilities.
* “Express Lanes Demonstration Program” allows tolling to finance new lanes. Automatic toll collection is REQUIRED and revenue collected may be used to provide a reasonable rate of return on PRIVATE financing, operation, and maintenance costs.
