Rhode Island is trying this. The gantries have been up for years, but it was challenged in court by the trucking lobby. The state prevailed with some concessions, and is planning to reinstate the truck tolls soon.

Probably, due to the small size of RI, it will just cause goods not bound directly for RI to divert along I-395 up through CT and MA, and I-290 and I-495 in MA.
