There are 12 testing lanes. Each full-scale test lane is 50 by 4 meters (165 by 13 feet), and can be further divided into 4 subsites, for a total of 48 test locations on the facility grounds. A supplemental three cell test pit is available for material testing. The test pit contains a reaction frame for load plate testing.
