Soil tests begin for Washington schemes

Washington State Department of Transportation has started drilling soil samples for two major projects, the US$500 SR 520 Bridge over Lake Washington and the US$2 billion Alaskan Way Viaduct replacement. Crews on the bridge project will work at 15 drilling locations in the lake, each of which will take about two days to cover. The existing structure is one of the world's oldest floating bridges. Six new drilling locations are being checked for the viaduct, following the earlier completion of investigations in the south and central project areas.

Important Update: Bridge Design & Engineering Magazine


For more than 31 years, Bridge Design & Engineering has been a trusted source of new insights, knowledge, and connections for the global bridge community.  With the rapid shifts in the publishing landscape and increasing costs, sustaining the printed magazine at the high level of quality our readers expect has become increasingly challenging.  After careful consideration, Hemming Group Ltd has made the difficult decision to discontinue the print publication.


You will continue to have full access to the Bridge Design and Engineering website - including the complete archive. Although the site will no longer be updated, the archive remains a rich resource of engineering knowledge and project insight.  You can also continue to access the Bridge Directory, IBIG, through the website or directly at: https://www.bdeibig.com/


While this marks the end of an era, it also opens a new chapter, one focused on strengthening the connections, collaboration, and technical excellence that our community thrives on.  Our energy and investment will now be directed toward expanding and enhancing our industry leading events that bring the bridge community together.


Our flagship events Bridges and Bridges Scotland will continue to thrive as essential annual gatherings for bridge owners, managers, designers, engineers, and suppliers.  These events play a vital role in sharing innovation, showcasing best practice and emerging technologies, and fostering meaningful collaboration across the industry.  We are excited to build on their success and will further develop these events in the years ahead.
