At the 18th Annual Convention of ARBA at the Coliseum in
Chicago, IL, Chief Thomas MacDonald discusses "Our
National Highway Problems." He says, "Let us not hope or
expect ever to find the final solution for all highway
problems, for they will continue on to the end of the
chapter, yet they will not be the same; or, at least, if
fundamentally the same, will appear in different guises
and with many modifications."
"Let it be clearly understood that the engineering and the economics cannot be separated, and that that engineering is best which does not design against every possible failure at an impossible cost, but which limits the number of failures to a low per cent." |
