A method is given for the design of a simply supported highway bridge con-structed of solid precast reinforced concrete slab units and two curb units. It is shown that this design improves the transverse wheel load distribution and an economical and practical bridge is achieved. The paper is divided into (a) a discussion of the variables affecting the transverse distribution of wheel loads, such as transverse stiffness factor, edge stiffness factor, and effective stiffness factor; (b) a design procedure investigating the effects of the longitudinal and transverse live load moments in the slab: and (c) numerical examples showing economy of the proposed structure.
