This report describes the development and testing of a guardfence-to-rigid bridge rail transition. The transition consists of a tubular W-beam supported on 7 inch diameter round wood posts. It is designed to transition to a vertical wall or to the concrete safety shaped barrier. It can be used on new construction or as a retrofit for existing installations. Based on a full-scale vehicular crash test program, the design was judged to be in compliance with recommended impact performance criteria as presented in NCHRP Report 230. Also described is a tentative design for approach guardfence at bridge ends near an abutting roadway. The design consists of short radius, curved guardrail supported on weakened round wood posts.

A Manual for Assessing Safety Hardware (MASH) Test Level 3 (TL-3) approach guardrail transition (AGT) was designed to connect the Midwest Guardrail System (MGS) to a MASH TL-4 steel-post, steel-tube, bridge rail, Type IL-OH. Two connection concepts were evaluated using the LS-DYNA finite element analysis computer software. The second concept was selected for further evaluation with full-scale crash testing, which included a previously-developed, thrie-beam, approach guardrail transition, modified HSS8x6x1/4 transition tube rails that aligned with the lower and middle bridge rail tubes, and new connection hardware designed to prevent vehicle snag during reverse-direction impacts. The critical impact points were selected using LS-DYNA for MASH test designation nos. 3-20 and 3-21 in the impact direction from the thrie-beam to the bridge rail. MASH test designation nos. 3-20 and 3-21 in the impact direction from the bridge rail to the thrie-beam AGT were determined to be non-critical. In test no. STBRT-1, the 2,404-lb small car impacted the AGT at a speed of 64.6 mph, an angle of 25.2 degrees, and at a location 21.3 in. upstream from post no. 19, thus resulting in an impact severity of 60.9 kip-ft. The small car was contained and redirected and resulted in a successful test according to MASH test designation no. 3-20 safety performance criteria. In test no. STBRT-2, the 5,007-lb quad cab pickup truck impacted the AGT at a speed of 62.7 mph, an angle of 24.9 degrees, and at a location 15.9 in. upstream from post no. 19, thus resulting in an impact severity of 116 kip-ft. The pickup truck was contained and redirected and resulted in a successful test according to MASH test designation no. 3-21 safety performance criteria.

Over one-half of 350 bridge-related fatal accidents in 1975 involved a collision with the end of a bridge rail. in some of these cases there was no approach guardrail. in other cases, the transition between the guardrail and the bridge rail deflected too much and allowed the vehicle to strike the bridge end. until recently, only a few crash tests had been conducted on guardrail to bridge rail transitions. a series of transition designs have been developed and tested that are significantly safer than many of the current standards. these improved designs are now being installed and should be in widespread use in the next few years. this paper presents detailed drawings of several designs, and briefly discusses the construction and maintenance considerations.

The objectives of this study were to develop safer bridge rail and transition designs and to improve design guidelines. Ten bridge railings and two transitions were designed, tested, and evaluated in accordance with American Association of State Highway and Transportation Officials (AASHTO) requirements. The railings were designed using ultimate strength procedures and collision forces from earlier research. Design procedures, railing designs, and test results are presented. All designs demonstrated acceptable collision performance.
