WSDOT Releases PGSuper 2.0

August 01, 2007 - Washington State DOT releases PGSuper 2.0. This major new version supports many new features including:

  • Multispan continuous structures
  • Support for provisions of the AASHTO LRFD Bridge Design Specification, 4th Edition, 2007.
  • Governing design parameters have been added to the design outcome report.
  • Shear stresses at the girder/slab interface can now be computed by either the LRFD approximate equations or by the classical shear flow equation, VQ/Ib.
  • You can now tag user defined loads with a text description. The tag can be used to find load values in reports.
  • User defined end moments have added.
  • Spread box beam bridges can now be analyzed and designed.

BridgeSight Signs Contract With Texas DOT for PGSuper Modifications

May 1, 2006 - BridgeSight Software signs contract with the Texas Department of Transporation Bridge Division to customize the open source girder design program PGSuper to fit TxDOT's needs for their LRFD implementation.

When finished, TxDOT will have a girder design program that is tailored to meet their needs at a fraction of the cost to develop software from scratch.
PGSuper is owned and developed by the Washington Department of Transporation, but its open source license allows others to modify and distribute the program freely. For more information about PGSuper, go WSDOT's software home page at:

Washington DOT Releases PGSuper 1.5

October 1, 2004 - PGSuper version 1.5 is released. After several minor releases, Rick Brice at WSDOT and Richard Pickings at BridgeSight Software have combined forces to deliver a major upgrade to PGSuper.
PGSuper is an MFC-based, Windows program for the design of precast girder bridges based on the AASHTO LRFD Specifications.PGSuper has a highly interactive graphical user interface that is designed for use in a production-engineering environment. Since its implementation, Washington State Department of Transportation engineers have reduced the time to design a bridge superstructure from ten days using previous methods to under five hours with PGSuper. This mature program is currently in its second major release with current development toward Version 2.0, which will include major features such as whole-bridge modeling, non-composite sections, and debonding..
