Who/what is going to pay for the road maintenance and construction if you repeal the gast tax? Really, with the utter lack of new road construction in the past 30 years while US population has grown 50%, we probably need a higher gas tax to finance lots more roads.
I don't know where you live, but they are building and rebuilding interstates all over the place here in W. Pa.... Toll Road built a few years ago, no one uses... ripping up and completely relaying large swaths of I79 that had just completeled a tear up and rebuild less than 10 years ago... putting in a Mon Fayette Expressway to connect a bunch of places no one wants to go to with a 4 lane interstate.....
No shortage of new construction or rehabilitation work at all around here.
