Pennsylvania is in the process of converting its tolling to a new vehicle classification structure, and eventually the weight class will be eliminated.
The conversion process began on April 29, 2018 at the Clark's Summit Toll Plaza and the Keyser Avenue Toll Plaza, both located at the north end of the Northeast Extension of the Pennsylvania Turnpike. Starting with these barriers, a new axle and height-based system is being tested and implemented.
This new axle and height system is similar to New York, using the same class identifiers as the NYS Thruway. See the insets for reference.

Cash will no longer be accepted at the Keyser Avenue and Clark's Summit Barriers, as Pennsylvania is moving to an open-road tolling system. If you use these barriers and do not have an E-ZPass or compatible toll pass, you will receive an invoice for your tolls.
