Resources for Bridge Owners and Designers
Approximately 310,000 (52%) of the bridges in the United States are classified as a city/county/township bridge (short span bridges). Approximately 25% of these bridges are structurally deficient or functionally obsolete. The Short Span Steel Bridge Alliance is working to support the needs of the bridge community through the development of educational and technical resources.
Steel offers solutions to any type of crossing. Short span steel bridges and buried soil structures can be built quickly, using local crews, and can be designed using prefabricated components which are simple to install and offer considerable cost savings. Steel offers a long service life with minimal maintenance, and provides unmatched sustainable benefits.
The following resouces provide further insight into the unique benefits of short span steel bridges and buried soil structures:
- 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.
- Case Studies – The SSSBA has developed dozens of case studies to showcase the use of steel in a variety of applications.
