PGSuper / BridgeLink (WSDOT)

Free Engineer & Analyze

Free, open-source bridge design, analysis, and load-rating software suite developed and maintained by the Washington State Department of Transportation (WSDOT) -- PGSuper for precast-prestressed concrete girder design (AASHTO LRFD), PGSplice for spliced post-tensioned girders, XBRate for reinforced concrete bent-cap load rating, plus BRIDG Concrete/Steel and BEToolbox utilities, bundled in the BridgeLink suite; used by state DOTs and bridge engineering consultants across the United States.

3.4 /5 composite score
C1 5/5 and C4 5/5 reflect a free, usable download with CSV and XLS export and no lock-in flag, while C2 2/5 reflects the WBFL C++ SDK and Barlist SDK rather than a public cloud API or CLI.
