Txdot Bridge Design Examples. This manual is intended to provide guidance for decisions in the bridge project process, to document or reference policies and standards that need to be considered and. A newly installed ton pedestrian bridge serving Miami's Florida International University collapsed, crushing several vehicles on a busy, multi-lane highway below and injuring multiple people. Mathcad enables engineers to easily perform, document and share calculation and design results. One design example is a two-span steel plate girder bridge, and the other is a two-span prestressed concrete girder bridge with simple span prestressed girders made continuous for live load.
