A transition for the Oregon side-mounted thrie-beam bridge railing was developed and tested to performance level one of the 1989 Guide Specifications for Bridge Railings. Acceptable performance of the transition was demonstrated. Post spacing in the transition area is 3 ft-1 1/2 in (953 mm). A 12 ft-6 in (3.81 m) length of thrie-beam which curves behind the guardrail post on the approach end is used in the transition.
