The Washington Department of Transportation (WSDOT) has developed this prestressed concrete girder program.  This robust, FREE, program has a fully interactive graphical interface, and supports AASHTO LRFD specifications.  This is the mainstay prestressed I-girder program for WSDOT designers.  This program is definitely worth the time to check out.

The State of Pennsylvania (PennDOT) has developed a concrete prestressed girder (PSLRFD) program and a steel superstructure (STLRFD) program.  Both of these inexpensive, yet comprehensive, programs support the AASHTO LRFD specifications.  Note that these programs are specifically written for PennDOT needs.
