Book Description
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.
