hahah how does tossing gravel/tar into the potholes work in that 30 year plan? Id venture to say the roads don't even make half that. The streets are so half assed its not even funny. I can't even enjoy my cars because odot clowns and their "30 year roads". I think the 30 year part is how often maintenance is done on them............We design for 30 years. Sometimes we miss the mark.
