Of course upping the gross weight limit, size and double tandem trailers had no effect on the roads either and as we all know the only reason they keep using asphalt instead of concrete is job security of the construction companies. At least that's here in PA and NJ.
Our ex gov Rendel was pissed when he found out that if he tolled the main highways he could not put the money in his own little slush fund to hand out as favors but each road had to have it's own 'account' and the tolls could only be used for that particular road. Once that was decided in court he decided to scrap the tolling completely and screw keeping up the interstates.
