This document is FHWA’s primary reference of recommended design and procurement procedures for shallow foundations.  The Circular presents state-of-the-practice guidance on the design of shallow foundation support of highway bridges.  The information is intended to be practical in nature, and to especially encourage the cost-effective use of shallow foundations
bearing on structural fills.  To the greatest extent possible, the document coalesces the research, development and application of shallow foundation support for transportation structures over the last several decades. Detailed design examples are provided for shallow foundations in several bridge support applications according to both Service Load Design (Appendix B) and Load and Resistance Factor Design (Appendix C) methodologies.  Guidance is also provided for shallow foundation applications for minor structures and buildings associated with transportation projects.
