New resources are available from the Federal Highway Administration (FHWA) to assist State transportation departments in implementing the Load and Resistance Factor Rating (LRFR) method for evaluating bridge condition and determining a load rating. Since October 1, 2010, all new bridges and bridges that are being completely replaced must be load rated using the LRFR method. The new method is improving the safety of bridges by incorporating state-of-the-art rating methodology for bridge loads. Load and resistance factors are calibrated using statistical data on loads and materials.
