DEC 13 1985 BOOK Commissioner Wodtke then brought up Bridge #4016 on 90th Avenue, which is a 33 ton bridge. He noted that Mr. Richardson has indicated that is a critical bridge as far as his hauling of fruit is concerned, and he wondered if there had been any discussion of this by the Citrus League. It was indicated there had been none. Commissioner Scurlock asked if we want to eliminate Kings Highway and approve the recommendation as is or if we want to allow flexibility for Golden River and modify the staff recommendation. Chairman Lyons expressed concern about the Board deciding something without actually knowing what a bridge will take. Administrator Wright requested that Mr. Davis explain the difference between the different ratings. Director Davis handed out a new map which reflects all the bridges in the county, and Commissioner Scurlock noted a bridge on 66th Avenue appeared to be posted for 6 tons. Director Davis explained that the green coloring on that bridge indicates that it is scheduled for immediate repair work. He then explained that the inventory rating is that at which structures can be utilized frequently without any restrictions for an indefinite period of time. On many of our bridges the most common inventory rating is 25 tons; that is the most conservative rating. The operating rating, or maximum rating, determines the ultimate strength of the bridge and is not a rating at which vehicles should be using that bridge at that weight limit for an indeterminate length of time. It would require more frequent inspection, better maintenance, etc. Commissioner Scurlock wanted the Director's recommendation as he is the professional and we are relying on him to inform us what is consistent with the Citrus League wishes and with our liability. Director Davis advised that his recommendation before he met with the Citrus League was to post most of these bridges at 33 110
