 2018 Prize Bridge Competition is Now Accepting Applications

The Prize Bridge Competition, a prestigious industry awards program organized by the National Steel Bridge Alliance, honors significant and innovative steel bridges constructed in the United States.  All award-winning bridges must be built of fabricated structural steel and located in the United States (defined as the 50 states, the District of Columbia, and all U.S. territories.) Eligible bridges must have been completed and opened to traffic between May 1, 2015 and September 30, 2017.

An independent panel of judges will select winners based upon the following criteria: innovation, aesthetics, economics, design and engineering solutions. Quality of submitted presentations, though not a criterion, is important.  Entries may be judged in more than one category, but an entry can only receive one award.

Winners will be notified shortly after judging and we will make a public announcement of the winners in Modern Steel Construction magazine. Designers of the winning Prize Bridge entries will be presented with plaques and honored during the World Steel Bridge Symposium. Owners of the winning Prize Bridge entries will be presented with plaques and honored at the NSBA networking event during the 2018 AASHTO Subcommittee on Bridges and Structures.

Award Categories

  • Major span - one or more spans greater than or equal to 400 ft.
  • Long span - Longest span equal to or greater than 250 ft but less than 400 ft.
  • Medium span - Longest span equal to or greater than 140 ft. but less than 250 ft.
  • Short span - No single span greater than 140 ft.
  • Movable span
  • Reconstructed - Having undergone major reconstruction, rehabilitation, or widening
  • Special purpose - Bridge not identifiable in one of the above categories including pedestrian, pipeline, and airplane

In addition to the above categories; NSBA will also offer special commendation to projects that best exemplify Accelerated Bridge Construction, and a full range of Sustainable attributes.

All entries are due by 11:59 pm, December 8, 2017.

About the Collaboration

The AASHTO/NSBA Steel Bridge Collaboration is a joint effort between the American Association of State Highway and Transportation Officials (AASHTO) and the National Steel Bridge Alliance (NSBA) with representatives from state departments of transportation, the Federal Highway Administration, academia, and various industry groups related to steel bridge design, fabrication and inspection. The mission of the Collaboration is to provide a forum where professionals can work together to improve and achieve the quality and value of steel bridges through standardization of design, fabrication and erection.


 Updated NSBA Splice Available for Download

Corresponding with changes made in the 8th Edition AASHTO LRFD Design Specification, the NSBA has released new guidance on bolted field splice connections. In the forthcoming Specification the design of bolted field splices has been simplified in an effort to generate more efficient and economical bolted connections. Complementing the 8th Edition Specification, NSBA’s document Bolted Field Splices for Steel Bridge Flexural Members provides a walkthrough of the updated design procedure as well as three complete design examples for typical plate girders, deep plate girders, and tub girders.

Additionally, NSBA’s Splice has been completely retooled. The new version of Splice is presented in an easy to understand Microsoft Excel spreadsheet format allowing users with Microsoft Excel 2010 or later to access and utilize.

NSBA Splice takes the time consuming task of designing and checking a bolted splice connection and makes the process simple with a straightforward input page and easily understandable output page..  NSBA Splice can be incorporated as a design tool on plate girder bridges allowing the designer to quickly analyze various bolted splice connections to determine the most efficient bolt quantity and configuration. Splice allows the user to explore the effects of bolt spacing, bolt size, strength, and connection dimensions on the overall splice design.

Included in the download is the design spreadsheet as well as two complete examples. The examples are the inputs and solutions for Examples 1 and 2 presented in Bolted Field Splices for Steel Bridge Flexural Members

SCOBS Networking Event was a Success Thanks to Our Sponsors

The 2017 NSBA Networking Event at the Mobius Science center was a great success for NSBA and the attendees. The event continues to grow with almost 200 people in attendance. This event wouldn’t be possible without the support from our sponsors: steel bridge fabricators, steel service centers, and steel mills.

For those unfamiliar with the NSBA’s networking event there are two important items to remember. 1) The event is always the Tuesday during the week of SCOBS. In 2018 that date is June 26 (mark your calendars now!), and 2) be ready to come and talk with designers, fabricators, DOT members, and NSBA staff about all things steel bridge. As the event nears the NSBA will provide emails to keep you up to date on times and location. If you are interested in receiving those correspondences please contact Matt Shergalis at shergalis@steelbridges.org.

Thank you once again to our sponsors and all those that attended. We look forward to make next year’s event in Burlington, Vt. even better.
