This document gave broad guidance on situations where uncoated weathering steel (UWS) should not be used or else used with caution. As stated in the technical advisory (TA), “Further work is needed to quantify and understand the performance of UWS in a variety of circumstances and conditions.” This report details a study conducted with the FHWA Long-Term Bridge Performance (LTBP) Program that contributes toward that goal, particularly considering longer term performance of UWS structures than was available at the time of the writing of the 1989 TA.
