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.

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 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.
