Wyoming has crash tested two types of TUBE-TYPE bridge railing. The most commonly used railing meets the crash test requirements of NCHRP Test Level 3 (TL-3). This railing uses two TS 6 x 2 x 0.250 for the longitudinal rail sections. The second rail type is designated as TL-4. It meets the crash test requirements of NCHRP Test Level 4. Truss Bridge Retrofit Railings - Texas A&M UniversityThe existing railing consists of a C12×20.7 (C310×31) mounted on truss members and intermediate posts. The retrofit design reused the existing channel rail element in combination with a W6×20 (W150×30) rail element to back up and stiffen the channel. New posts were designed to mount on the concrete safety walk.
