ATA Engineering completes testing of modular bridge design

San Diego-based ATA Engineering Inc., Wednesday announced the successful completion of proof testing of the ARCS deployable bridge system.

Technologies incorporated in the ARCS bridge result from a three-year effort funded by the U.S. Army's TARDEC (Tank Automotive Research, Development and Engineering Center).

The prototype is a 7,000-pound bridge constructed from six segments of interleaved aluminum modules designed to accommodate crossing by a 30-ton vehicle over a 40-foot gap. Static testing was successfully performed up to 42 tons.

The reconfigurable design addresses several shortcomings of today's temporary bridging technologies: Unlike other systems that require significant logistical support to deploy and are limited to a fixed span and load capacity, ARCS can be deployed rapidly while remaining adaptable to different gap widths and loads. Fulfilling the need for a "bridge-in-a-box," a deployment-ready 80-foot bridge can be transported inside a standard shipping container.

Future development is expected to demonstrate the system's capability at spans exceeding 100 feet and for vehicles in excess of 75 tons.
