The department said Thursday that the state tolled 200,746 big rigs at two toll locations - more than 23,000 more than expected. The Providence Journal reports the tolls resulted in $664,617 in assessed charges, $65,950 more than estimated.
Rhode Island began charging tractor-trailers at two spots on Interstate 95 on June 11 despite opposition from the trucking industry. The industry has filed a lawsuit challenging the system's constitutionality.
Democratic Gov. Gina Raimondo's administration says it plans to add another dozen toll locations to the system.
