Taking on America’s Infrastructure Challenge, One County at a Time
The Short Span Steel Bridge Alliance (SSSBA) has developed design tools and educational sessions for county engineers, bridge owners and designers to equip them to move forward. Steel is an optimal material for short span bridges, ensuring durability, speed of design and construction, ease of installation, light weight, the use of local crews, cost-effectiveness and time efficiencies.
- eSPAN140 – A free, web-based design tool that provides customized short span steel bridge solutions in less than five minutes. To access this tool, users go to espan140.com; type in the parameters for their projects such as span length, width and the number of striped traffic lanes; and receive customized preliminary designs and the names of suppliers and fabricators who can take the project from concept through completion. Since 2012, more than 1,300 preliminary designs have been generated by eSPAN140.
- Short Span Steel Bridge Workshops – The SSSBA offers complimentary educational on-site workshops specifically for county engineers, state DOTs, and design firms. The half-day (or full day) workshops provide practical information on the safe and cost-effective design, detail, fabrication and installation of short span steel bridges (under 140 feet)―including information on standardized designs developed by the bridge industry.
- Steel Bridge Forum – The SSSBA supports the National Steel Bridge Alliance (NSBA) to conduct one-day Forums that cover short-, medium- and long-span steel bridge design, and associate research. The Steel Bridge Forums are conducted throughout the U.S. and are ideal for Departments of Transportation.
- National/Regional Bridge Conferences – SSSBA representatives and county engineers discuss short span steel bridge design and construction at several conferences throughout the year. Our experts are available to provide presentations on topics specific to bridge design and construction.
- Webinars – The SSSBA hosts one-hour webinars on short span steel bridge design that are eligible for Professional Development Hours (PDHs), conducted by Dr. Michael Barker at the University of Wyoming, Dr. Karl Barth at West Virginia University, Dr. Greg Michaelson at Marshall University and special guest speakers.
- Project Assistance –The SSSBA offers complimentary design support for questions relating to bridge and buried soil steel structure design. The topics include standard design and details of short span bridges (plate girder and rolled beams, buried bridge, press brake tub girders), prefabricated short span steel solutions, durability solutions, and more.
- Case Studies and Videos – Efficiencies in design, cost and time on specific projects are documented in case studies on the SSSBA website.
Steel buried bridges are durable and resilient, with the ability to support very heavy loads.
