"This synthesis report will be of interest to state highway design engineers and structural engineers, as well as environmental and historic preservation personnel in transportation agencies. It will also be of interest to state historic preservation offices, federal historic preservation agencies, ang engineering preservation consultants"--Avant-propos.

Michigan's historic highway bridges are rapidly being torn down and replaced as they deteriorate or become unable to support increased traffic volumes and loads. While the state has the responsibility of providing safe bridges, historian Charles K. Hyde maintains that the state must also preserve many of these remaining historic structures to insure that future generations will have them to view and appreciate. In Historic Highway Bridges of Michigan, Hyde identifies Michigan's historically significant highway bridges within the broader contexts of American bridge design and construction in the 19th and 20th centuries. The book summarizes the improvement of highway bridge design in the United States and compares Michigan's experiences with national trends. To aid the reader interested in visiting the historic highway bridges of Michigan, regional maps show the location of bridges included in the text.

Modern structural engineering surprises us with the mastery and certainty with which it plans and carries out daring projects, such as the most recent metal or concrete bridges, whether they be suspension or arch bridges. On the other hand, little is yet known about the state of knowledge of construction science and techniques which, well before the arrival of modern methods based on the mechanics of deformable continua, made it possible in the past to erect the vaulted masonry structures rthat we have inherited. The fact that these have lasted through many centuries to our time, and are still in a fairly good state of conservation, makes them competitive, as far as stability and durability are concerned, with those constructed in other materials. Although it is known that the equilibrium of the arch is guaranteed by any funicular whatsoever of the loads, contained inside the profile of an arch, finding the unique solution is not such a certainty. In other words, the problem of the equilibrium of vaulted structures is 'Poleni's problem', the one for which the Venetian scientist was able to give an exemplary solution on the occasion of the assessment of the dome of St. Peter's. Arch Bridges focuses on the main aspects of the debate about the masonry arch bridge: History of structural mechanics and construction, theoretical models, analysis for assessment, numerical methods, experimental and non-destructive testing, maintenance and repair are the topics of the Conference. The breadth and variety of the contributions presented and discussed by leading experts from many countries make this volume an authoritative source of up-to-date information.

This comprehensive guide provides the reader with basic information of the most common types of structures, sites, and objects encountered in industrial archaeology. These include bridges, railroads, roads, waterways, several types of production and extraction factories, water and power generating facilities, and others. Each chapters contains a brief introduction to the technology or features of each class of installation, illustrations with characteristics that help identifying important elements of the type, and a glossary of common terms. Two chapters offer valuable guidance on researching industrial properties and landscapes. For students, avocational archaeologists, and cultural resource management surveys, this volume will be an essential reference.
