They, the interstates, are mainly decrepit in urban areas. The municipalities and states where they are should use their damned state gas tax money to fix them.
I further “propose” to stop wasting federal gas taxes on BS studies, programs and everything not related to actual repairs - that includes the 20% of funding it uses to support subsidized mass transit where they pander to riders whose only merit is that they ‘vote’.
And what are the municipalities supposed to use to fix their surface streets?
