Response
The 3366mm length of thrie beam is as specified on past sites. The length is intended to suit the truss panel spacing of the modular bridge. The lengths shown on the Contract Drawings have successfully been supplied by modular bridge manufacturers in the past. The back-up plate is a section of thrie beam rail (which is galvanized) installed as reinforcing at intermediate posts where there is no splice. This applies only at the approach ramps.
