Abstract:
The Duwamish River Bridge is a post-tensioned segmental concrete bridge that won the bidding contest against steel by $16 million. The project contains complexities typical of those that may be encountered in major urban construction in these days of changing outlook and procedure. The article discusses the scope and design approach including problems with poor foundation conditions, seismic considerations and provisions for future widening of the navigable channel to the Seattle harbor.
