In 1927, the American Bridge Company at Ambridge, Pa., constructed a steel hull measuring 169.8 feet in length by 38.9 feet in width and having a depth of 6.5 feet for the Carnegie Steel Company, which had contracted for the new tow-boat in 1924. Named Monongahela, the vessel was completed at Coal Valley, Pa., and it was a sister boat to the City of Pittsburgh. The engines were rated at 1,400 hp., powered by steam from five return-flue boilers. The compound condensing engines contained cylinders of 18 and 36 inches with a stroke of 8.6 feet. The sternwheel was 26.5 feet in diameter with 16 buckets having a dip of 38 inches. The pitmans that connected the paddlewheel to the engines were named "Colonel Charles A. Lindbergh" and "Spirit of St. Louis." |
