Bridge Classifications

Bridge signs were usually a 9" yellow disc with black numbering. Sometimes a black disc was used with the number outlined in yellow. The correct shade of yellow is 356 (previously No56) Golden Yellow from BS381-C.

Examples of signs, the first has a weight classification of 5 tons the second is for a towing vehicle of 18 tons with a combined load of 50 tons.
