About Bridge Design
Autodesk Bridge Design for InfraWorks gives you the tools to model and design bridges in the context of your overall infrastructure design project. 
About Bridges
InfraWorks supports Precast I Girder and Steel Plate Girder bridge types, which support different bridge deck, abutment, piers, girder, and bearing components. Default settings for these concrete and steel bridge types are represented by concrete and steel bridge assemblies within the Bridge catalog of the Style Palette. You can also modify these bridge styles, or create new ones to apply to your bridge. Bridges can be added to component roads using right-click menu options. See To add a bridge to a component road.
Review material quantities
Use the quantities tool to review material quantities for a selected bridge or individual bridge component. See: To review bridge material quantities.
Review and modify attributes
Review and modify bridge, girder group, girder, abutment, pier, foundation, and deck attributes in the Stack. Choose from a catalog of parametric component parts for abutments, piers, and pier foundations.

Author Parametric Bridge Parts
Use the Infrastructure Part Shape Utilities tools for Autodesk Inventor to create your own parametric shape templates, parts, and assemblies, then export those parametric models for use in InfraWorks bridge design. See About Parametric Bridge and Tunnel Components.
Advanced capabilities
- Perform line girder analysis and design on all pre-stressed girders for a selected bridge.
- Perform refined bridge analysis for a selected bridge. Refined bridge analysis exposes three additional approaches: grillage, offset girder and finite element models. These allow users to create analysis models that better reflect the actual layout of the bridge girders. Alignments with plan curvature, skewed piers and abutments are taken into account
- Open your bridge design in Autodesk AutoCAD Civil 3D. See About Exchanging Data with AutoCAD Civil 3D.
- Send your bridge design to Autodesk Revit. See To publish civil structures to Autodesk Revit.
