This route is a different and mostly unknown way to cross the river Tejo. The narrow road runs mostly trough tomato fields and by two small airfields before reaching the small bridge. This is a one way bridge so you might have to wait some minutes at the lights.
WARNING: The bridge has a steel mesh surface! This is a dangerous surface for a two-wheeled vehicle so calculate well the risk of crossing it! Maintain a low constant speed and dont get distracted by the scenery.
