Although the above described temporary bridge systems are widely used throughout Europe and Asia as an acceptable solution to permanent bridge replacement, the findings from this project indicate that the United States has been slow to adopt these designs for permanent bridges which can be attributed to the lack of well established fatigue criteria and the extensive effort necessary to maintain these bridges. Figure 2.6: Hand Assembly of Bailey M2 Bridge. Secondly, in the transverse direction, the required restraint is provided through the addition of external steel straps, normally 1 inch x 2 inches in cross-section and spaced at about 4 feet on centers, which inhibit the lateral displacement of adjacent girders.
