The steel-grid bridge deck of I-10 over the Pascagoula River was completed approximately three years before it was opened to traffic. The first series of skid tests produced very high skid numbers; but the steel polished under the small volume of construction traffic and the numbers dropped a great deal during the three years of light construction traffic. After it was opened to through traffic, the skid numbers decreased rapidly for about a year. During the next six months, they bottomed out and were expected to stabilize. Instead, they started increasing. After construction of the steel-grid bridge deck, but before completion of the approaches, there was concern about its rideability, which led to several special inspections and driving tests both before and after opening to traffic. The annual inspections proved to be worthwhile. It is recommended that annual inspections be required for all steel-grid bridge decks.
