摘要：	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.
