Today's bridge designers are essentially striving to achieve the same goals as their counterparts were 70 years ago: long-term serviceability, low maintenance characteristics, and economy of construction. While new techniques have been mastered such as welding, composite decks, Load Factor and Autostress designs, designers still cling to many old ideas that lessen the potential for achieving their goals. One of the more important aspects of design — reduction or elimination of roadway expansion devices and associated bearings — is consistently overlooked or avoided by many bridge-design practitioners. As a result, this chapter on jointless bridges utilizing integral abutments has been developed to discuss issues ranging from their historical development through their design implementation to help provide the necessary understanding for today's bridge engineer.
