In November 2004, the state government declared the trial a success, using data that showed only three crashes in the nine-month trial period. The data did not include vehicle breakdowns on the bridge that would have involved delays from blocked lanes. Prior to the permanent speed limit being announced, a four-vehicle crash occurred with a motorist trapped in her car, closing the bridge in the evening peak for three hours, and again caused banked-up traffic for several kilometres and forced motorists to take the longer western route via the Bruce Highway.
