Maryland E-Z Pass customers and truck drivers will pay more to travel through toll facilities, under a new proposal to offset declining revenues, state transportation Secretary John Porcari said Monday.

The Maryland Transportation Authority gave preliminary approval to a $60 million “cost recovery” plan that includes a $1.50 monthly service fee for E-Z Pass, a $21 fee for the system’s electronic devices — which are currently free — and increased tolls for multi-axle vehicles.
