English: A streetcar sharing the [Washington-Oregon] Interstate Bridge with cars, most of them Model T Fords. A marker was placed at the foot of the bridge by the Daughters of the American Revolution with an inscription by the English writer Thomas Babington Macaulay, which reads: “Of all inventions, the alphabet and the printing press alone excepted, those inventions which abridge distance have done most for the civilizations of our species. Every improvement of the means of locomotion benefits mankind morally and intellectually as well as materially, and not only facilitates the interchange of the various productions of nature and art, but tends to move national and provincial antipathies, and to bind together all the branches of the great human family.”
