Your bridge will carry your 135 just fine without footings for a few years. The way it sounds you won't use it much. With no footings it will settle into the ground on it's own without being driven over and if it settles the same in all four corners, fine but usually it doesn't happen that way. A bridge that moves around when you drive over it doesn't give you much of a sense of confidence. You could lay heavy creosoted planks under the ends to help with the settling but concrete pillars sunk in deep is the only way you can guarantee it will stay up straight and square. But again, maybe for your application going the concrete pillar way is too much money.
The people I harvest with have a 40' long by 12' wide plank bridge with no railings that we used to drive big combines over. It was scary sitting way up there in the combine cab looking way down into the creek below to say the least. Eventually one corner settled so when the front combine wheels went on the bridge the other end of the bridge would lift up a bit and stay up for awhile until the weight of the combine brought it back down. It was enough to make an atheist pray. We don't drive combines or trucks over it any more but it still is unsettling to me just driving a pickup on it.
