An aesthetic, see-through concrete bridge rail, Type 80, was built and tested in accordance with National Cooperative Highway Research Program (NCHRP) Report 350. The Type 80 bridge rail is an 810 mm-tall, reinforced concrete barrier. The rail has 280 mm-high by 1620 mm-long gaps, 230 mm above the bridge deck surface. The barrier tested was 23 m-long and was constructed at the California Department of Transportation (Caltrans) Dynamic Test Facility in West Sacramento, California. A total of three crash tests were conducted under NCHRP Report 350 Test Level 4, one with an 820 kg car, one with a 2000 kg pickup truck and one with an 8000 kg single unit van truck.

A bridge rail Type 70 was built and tested in accordance with NCHRP Report 350. The Type 70 bridge rail is an 810 mm tall concrete barrier with a sloping face of 9.1 deg from the vertical. The barrier tested was 22.9 m long and was constructed at the Caltrans Dynamic Test Facility in West Sacramento, California. A total of four crash tests were conducted under NCHRP Report 350 test level 4, one with an 820 kg car, two with 2000 kg pickup trucks and one with an 8000 kg van truck. Both the 820 kg and the 8000 kg tests were within the limits of NCHRP Report 350 guidelines.

Over the course of this project a see-through steel bridge rail (Type California ST-20) was developed and tested. The ST-20, as tested, is at the limits of meeting the NCHRP Report 3501 TL-4 test matrix. The bridge rail also met the requirements established in the AASHTO Bridge Design Specifications for use as a bicycle rail and is considered an aesthetically pleasing see-through bridge rail. The barrier, as tested, uses steel posts at 3-m spacing to support four boxbeam rails and one additional handrail to meet the height requirements for bicycles. Because the ST-20 is based on a TL-4 bridge rail from Wyoming DOT3,4, only Test 4-11 (NCHRP Report 350) was considered necessary.

A total of seven vehicle crash tests were performed, three involving a Type 115 bridge rail and four involving a thrie beam bridge rail. Additional static testing was done on five steel bridge rail posts with different types of post stiffeners. The Type 115 bridge rail consisted of two tube steel rails (4x4x0.25 in.) supported off the edge of deck by steel wide flange posts at 8 ft 0 in. spacing. The thrie beam bridge rail consisted of 10 ga. thrie beam panels blocked out and supported on the edge of deck by steel wide flange posts at 6 ft 3 in. spacing. The typical heights for the Type 115 and the thrie beam bridge rails were 30 and 32 in., respectively. There were two impact tests on the Type 115 bridge rail, one on the Type 115 bridge rail transition, two on the thrie beam bridge rail, and two on the thrie beam bridge rail transition.

"The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units-metric and U.S. Customary. This book is a guide. It is not a standard, nor is it a design policy. It is intended to use as a resource document from which individual highway agencies can develop standards and policies. Although much of the material in the guide can be considered universal in its application, several recommendations are subjective in nature and may need modification to fit local conditions. However, it is important that significant deviations from the guide be based on operational experience and objective analysis. The 2011 edition of the AASHTO Roadside Design Guide has been updated to include hardware that has met the evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features and begins to detail the most current evaluation criteria contained under the Manual for Assessing Safety Hardware, 2009 (MASH). For the most part, roadside hardware tested and accepted under older guidelines that are no longer applicable has not been excluded in this edition." -- AASHTO website.
