This synthesis will be of interest to state department of transportation bridge design and structural engineers, bridge consultants, and others involved in applied and research methods for increasing the live load capacity of existing highway bridges. The synthesis describes the current state of the practice for the various methods used to increase the live load capacity of existing highway bridges. This is done predominantly for bridges in the short- to medium-span range. Information on the more common bridge material types is presented. There is an emphasis on superstructure rather than substructure strengthening.

This compelling collection of essays explores the Qhapaq nan (or Great Inca Road), an extensive network of trails reaching modern-day Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. These roads and the accompanying agricultural terraces and structures that have survived for more than six centuries are a testament to the advanced engineering and construction skills of the Inca people. The Qhapaq nan also spurred an important process of ecological and community integration across the Andean region. This book, the companion volume to a National Museum of the American Indian exhibition of the same name, features essays on six main themes: the ancestors of the Inca, Cusco as the center of the empire, road engineering, road transportation and integration, the road in the Colonial era, and the road today. Beautifully designed and featuring more than 225 full-color illustrations, The Great Inka Road is a fascinating look at this enduring symbol of the Andean peoples' strength and adaptability.
