Suspension Bridges
Types of Bridges What are bridges used for? What bridges have you seen in real life? Where were they? Were they designed for people to walk over? Do you know the name and location of any famous bridges? Did you know that there is more than one type of design for bridges? Let’s take a look at some of them. Suspension Bridges A suspension bridge uses ropes, chains or cables to hold the bridge in place. Vertical cables are spaced out along the bridge to secure the deck area (the part that you walk or drive over to get from one side of the bridge to the other). Suspension bridges can cover large distances. Large pillars at either end of the waterways are connected with cables and the cables are secured, usually to the ground. Due to the variety of materials and the complicated design, suspension bridges are very expensive to build. Suspension Bridges The structure of suspension bridges has changed throughout the years. Jacob’s Creek Bridge in Pennsylvania was built in 1801. It was the first suspension bridge to be built using wrought iron chain suspensions. It was 21 metres long. If one single link in a chain is damaged, it weakens the whole chain which could lead to the collapse of the bridge. For this reason, wire or cable is used in the design of suspension bridges today. Even though engineer James Finlay promised that the bridge would stay standing for 50 years, it was damaged in 1825 and replaced in 1833. Suspension Bridges Akashi Kaiko Bridge, Japan The world’s longest suspension bridge is the Akashi Kaikyo Bridge in Japan. -
Alameda, a Geographical History, by Imelda Merlin
Alameda A Geographical History by Imelda Merlin Friends of the Alameda Free Library Alameda Museum Alameda, California 1 Copyright, 1977 Library of Congress Catalog Card Number: 77-73071 Cover picture: Fernside Oaks, Cohen Estate, ca. 1900. 2 FOREWORD My initial purpose in writing this book was to satisfy a partial requirement for a Master’s Degree in Geography from the University of California in Berkeley. But, fortunate is the student who enjoys the subject of his research. This slim volume is essentially the original manuscript, except for minor changes in the interest of greater accuracy, which was approved in 1964 by Drs. James Parsons, Gunther Barth and the late Carl Sauer. That it is being published now, perhaps as a response to a new awareness of and interest in our past, is due to the efforts of the “Friends of the Alameda Free Library” who have made a project of getting my thesis into print. I wish to thank the members of this organization and all others, whose continued interest and perseverance have made this publication possible. Imelda Merlin April, 1977 ACKNOWLEDGEMENTS The writer wishes to acknowledge her indebtedness to the many individuals and institutions who gave substantial assistance in assembling much of the material treated in this thesis. Particular thanks are due to Dr. Clarence J. Glacken for suggesting the topic. The writer also greatly appreciates the interest and support rendered by the staff of the Alameda Free Library, especially Mrs. Hendrine Kleinjan, reference librarian, and Mrs. Myrtle Richards, curator of the Alameda Historical Society. The Engineers’ and other departments at the Alameda City Hall supplied valuable maps an information on the historical development of the city. -

Visit Ohio's Historic Bridges
SPECIAL ADVERTISING SECTION Visit Ohio’s Historic Bridges Historic and unique bridges have a way of sticking in our collective memories. Many of us remember the bridge we crossed walking to school, a landmark on the way to visit relatives, the gateway out of town or a welcoming indication that you are back in familiar territory. The Ohio Department of Transportation, in collaboration with the Ohio Historic Bridge Association, Ohio History Connection’s State Historic Preservation Office, TourismOhio and historicbridges.org, has assembled a list of stunning bridges across the state that are well worth a journey. Ohio has over 500 National Register-listed and historic bridges, including over 150 wooden covered bridges. The following map features iron, steel and concrete struc- tures, and even a stone bridge built when canals were still helping to grow Ohio’s economy. Some were built for transporting grain to market. Other bridges were specifically designed to blend into the scenic landscape of a state or municipal park. Many of these featured bridges are Ohio Historic Bridge Award recipients. The annual award is given to bridge owners and engineers that rehabilitate, preserve or reuse historic structures. The awards are sponsored by the Federal Highway Administration, ODOT and Ohio History Connection’s State Historic Preservation Office.

Toll Roads in the United States: History and Current Policy
TOLL FACILITIES IN THE UNITED STATES Bridges - Roads - Tunnels - Ferries August 2009 Publication No: FHWA-PL-09-00021 Internet: http://www.fhwa.dot.gov/ohim/tollpage.htm Toll Roads in the United States: History and Current Policy History The early settlers who came to America found a land of dense wilderness, interlaced with creeks, rivers, and streams. Within this wilderness was an extensive network of trails, many of which were created by the migration of the buffalo and used by the Native American Indians as hunting and trading routes. These primitive trails were at first crooked and narrow. Over time, the trails were widened, straightened and improved by settlers for use by horse and wagons. These became some of the first roads in the new land. After the American Revolution, the National Government began to realize the importance of westward expansion and trade in the development of the new Nation. As a result, an era of road building began. This period was marked by the development of turnpike companies, our earliest toll roads in the United States. In 1792, the first turnpike was chartered and became known as the Philadelphia and Lancaster Turnpike in Pennsylvania. It was the first road in America covered with a layer of crushed stone. The boom in turnpike construction began, resulting in the incorporation of more than 50 turnpike companies in Connecticut, 67 in New York, and others in Massachusetts and around the country. A notable turnpike, the Boston-Newburyport Turnpike, was 32 miles long and cost approximately $12,500 per mile to construct. As the Nation grew, so did the need for improved roads.
