Data for use in designing culverts and short-span bridges
A technical bulletin of standard culvert and short-span bridge designs compiled by Charles H. Moorefield for the U.S. Office of Public Roads and issued by the Government Printing Office in Washington in 1913, addressed to county road engineers and builders. The plates are line-drawn engineering plans, sections and elevations with dimension lines, lettered callouts and hatched or stippled fills indicating concrete, rubble and brick, useful for diagrammatic textures, measured-drawing layouts and hand-lettered annotation.
