California has used a 32-inch high concrete parapet bridge rail with a New Jersey profile as the standard for most bridges in the past 10 years. A few transportation districts requested an alternate design that would allow motorists to see through the rail better in scenic areas. With this impetus, Caltrans proceeded to develop and crash test a new bridge barrier railing. Two crash tests were conducted. Static crush tests were also conducted on two steel pipe rings. The new design called Metal Railing (Tubular) Type 18 has been adopted as a standard and is ready for trial use.
