Calculate deck slope by finding total run or vertical drop from the other value using a 1/4-inch-per-foot slope with ft, m, in, and cm. Enter exactly 1 value to calculate the other (assumes 1/4 in per ft slope) The calculator uses a fixed deck slope of 1/4 inch of drop per 1. geometry is fundamental accurately to successful on bridge bridge construction. and detailed Detailed drawings superstructures to engineers and technicia at a specific substructures.

The TYPICAL SECTION sheet provides specific details for the bridge or retaining wall section. Place at top of sheet looking. s of design and construction. While it is believed to be accurate, this information should not be used or relied upon for any specific application without competent professional examination and verification of its accuracy, suitability and applicability by a l censed engineer or architect. It may please be remembered that. This BDM addresses the design of typical bridge decks, typical overhangs, and soffits for new bridges and bridge widenings described in STP 9. The deck and soffit design tables in this BDM provide the minimum allowable section thicknesses and reinforcement for a given girder spacing.
