A bridge span assembly can include multiple bridge spans, each of which can include a frame, a stabilizing member for engaging with construction equipment, and a coupling joint for attaching the frame to construction equipment with an elongate member. By attaching the bridge span assembly to construction equipment with the stabilizing member and coupling joint, an operator can place the bridge span assembly over an obstacle using only the construction equipment. The construction equipment or other equipment can then safely traverse the obstacle without causing damage to the obstacle or the construction equipment.
