TO the Editor of "The Structural Engineer.” Sir,-I was unfortunately unable to be present at Mr. Bossom’s paper, and was somewhat surprised to note that neither in the paper nor in the discussion was any reference made to the sections which are now being rolled by the Carnegie Steel Co. and marketed by the United States Steel Products Co. These new sections include a 14 in. H section, maximum weight which is 305 Ibs. per foot, with sectional areas of 89.7 square inches. For column lengths not exceeding 20 ft. this is listed to carry 1,346,000 lbs.
In order to appreciate modern Road Construction it is necessary to review the history of the road as far as our own country is concerned; for only in this way is it possible to understand fully the difficulties which have troubled the highway engineer in the past; many of which are still a hindrance to efficient road construction. G. McLean Gibson
In the year 1926 was commenced the construction of the world's largest bridge. The year 1932 is expected to witness its opening to traffic. Its ofiicial name is the Hudson River Bridge and it will span the Hudson River between Fort Washington in the State of New York and Fort Lee in the State of New Jersey. This bridge will provide highway and electric railway transit over the main channel of the Hudson River. Its location, together with that of other links between New York, Brooklyn, Manhattan and New Jersey, is indicated in Fig. 1. The bridge is being built by the Port of New York Authority, pursuant to authority conferred by joint action of the States of New York and New Jersey. The financing was effected by the Port Authority authorising an issue of 60 million dollars, Port of New York Authority, New York-New Jersev Interstate Bridge Gold Bonds, 30 millions of which were sold on December 9, 1926, to the underwriters; and by the States of New York and New Jersev, by appropriate legislation, making available to the Port Authority the sum of 10 million dollars. The 20 millions of bonds sold to the public bear interest at the rate of 4 per cent. They were sold to the public on a basis to yield 4.20 per cent., and are today selling in the open market on a 4 per cent. yield basis. Professor J. Husband
