An analysis multi criterion of the three variants is established. To the descended of this analysis, the most advantageous variant is kept and made the object of a pre-dimensionality. The calculation of the permanent loads and overcharges of exploitation have been led. In order to succeed to a faithful representation of the real behavior of the chosen variant, a three-dimensional model in finished elements has been achieved while adopting the code of calculation CSI Bridge 2017. A study of the prestressing, as well as the evaluation of the losses due to prestressing have been established. While using the model 3D, a static and dynamic survey has been presented follow-up of the interpretation of his/her/its results. Finally, the stability of the abutment is verifiedviaduct, hollow box, flail cable, load and overload, static and dynamic analysis.
