Writer states that concrete barrel and rib arches for bridge spans are advantageously carried on falsework truss centers for spans of more than 25 or 30 ft., especially if very high or over spaces where obstructions are objectionable. Steel trusses are said to be more economical, safer, stiffer, more accurate and reliable, and more easily and cheaply handled, and can be rented or bought and salvaged.
