Barge Building Yard of the American Bridge Co., Ambridge, Pa. Build Modern Floating Equipment for River Traftic Expansion APID growth has characterized R traffic over the Ohio river system in recent years. Work now in progress or contemplated in furthering the navigability of the va- rious streams indicates that addi- tional substantial expansion in river tonnage and an increase in river craft construction may be anticipated in the next few years. The Ohio river system drains the most highly developed industrial dis- trict in the United States. On or near the river banks are enormous deposits of mineral wealth, including coal, fire clay and_ lime- stone. At the _ confluence of the Allegheny and Mo- nongahela rivers where the Ohio begins, is located in Builder Location Number Tons steel reat s Imaki Ls American Bridge Co..........cccccccccsssecesess Ambridge, Pa. 182 the ¢ t tee aking cen Dravor Contracting’ © Coss. iccccdscapssacesseckeesaves Pittsburgh 118 ter of Pittsburgh.

Gude carries a large tonnage of coal to the many steel mills along its banks and flows through an active industrial section. The Allegheny river and its tributaries are im- portant branches of the Ohio and are the potential sources of a large amount of commerce. Champions of improvement of the Kiskiminetas and Conemaugh rivers to provide an out- let to the Allegheny maintain that more than 6,000,000 tons of iron and steel annually are available for river transportation in that district, while a billion and a half tons of coal can River Hull Launchings— 1927 Howard Shipyards & Dock Co....Jeffersonville, Ind. 387 Charles Ward Eng.

Low bridges near the mouth of the Allegheny, formerly deterrents’ to transportation, have been removed as far as 31.5 miles above Pittsburgh, and construction of dams now being planned will establish a navigable slackwater to Rimerton, Pa., 61 miles above the mouth. On the Ohio, work is nearing com- pletion on locks and dams which soon will make this stream available for year-round transportation to the Mississippi, a distance from Pittsburgh of nearly 1000 miles, and_ thence south to the Gulf of Mexico. pene This construction work on 9,000 various streams of the sys- oe. tem opens new transporta- ace tion fields to shippers.
