Are you allowed to stop your vehicle on this bridge, in order to drop off passengers?

The regulations explicitly prohibit stopping a vehicle on a bridge. According to Art. 49 para. 1 pt. 3 of the Road Traffic Act, this prohibition applies to bridges, viaducts, and tunnels. The ban is in effect regardless of the reason for stopping, including to let a passenger out, as it obstructs traffic and creates a hazard for other drivers.
