A joint venture of Obayashi and PS Mitsubishi Construction is the apparent low bidder for the Colorado River Bridge, just downstream from the Hoover Dam. The team beat three others with its bid of US$114 million, which was US$17.8 million above the engineer's estimate. When time costs of $8,000/day are factored in, the total cost comes to US$123.7 million, against an engineer's estimate of US$106.4 million.
The second placed bidder was a joint venture of Kiewit and Flatirons with a bid of US$127 million and a total cost of US$135.8 million. The other bidders were a Kraemer/Taisei JV and Traylor Brothers.
The bridge will take the form of a 580m composite concrete deck arch. Concrete will be used for the arch and columns and the upper deck structure will be of steel.
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.
