Show ROAD CONSTRUCTION IS SLOW Estimated That United States Spending Spend-ing About $250,000,000 Annually on Improvements. Road construction is bound to be slow because of its great cost. Figures Fig-ures show that the average cost of sand-clay roads in the United States is $700 a mile, of gravel roads $2,000, of macadam $5,000 and of asphalt macadam $10,000 a mile. It has been estimated that the states are spending about $250,000,000 a year on roads, and the expenditure is increasing in-creasing every year. Europe has a great advantage over us, because the old countries have handed down to them the best kinds of roads for centuries. |
