This report provides proposed load and resistance factor design (LRFD) bridge design pier protection specifications and proposed occupant protection guidelines to update the AASHTO LRFD Bridge Design Specifications and AASHTO Roadside Design Guide, respectively. The proposed specifications and guidelines are based on a comprehensive analytical program that used a risk-based approach for investigating the effects of a heavy truck hitting one or more bridge columns or piers. The report also includes four examples that illustrate the use of the proposed specifications and guidelines for shielding bridge piers.
