Advantages encompass decreased value as opposed to double girder and lighter wheel loading thus reducing constructing and/or runway costs. Disadvantages include much less hook peak viable, now not as durable and trolley is in a suspended function as opposed to jogging on pinnacle of bridge beams (on heavy programs untimely beam put on has been cited).
