Very frequent crossings, basically non-stop during the day. There is a person selling tickets onboard so you don't need to buy one in advance through the machines that only take small coins. Was only 90c for me and my bike.

World Heritage Site and the first suspension bridge of its kind in the world. More than 100 years old and it is still operational, linking the two banks of the estuary 365 days a year, 24 hours a day.
