Old Seven Mile Bridge, Marathon

4.6
Drive, ride a bike, or take a walk across Old Seven Mile Bridge to admire the engineering marvel and the scenic views it provides. Spanning 10.9 km (6.8 mi), the bridge was one of the longest in the world when it was built. Nowadays, an adjacent modern bridge caters to vehicular traffic, while the old bridge--which served as a part of the railway network in the past--is presently open for walking and cycling only. Go fishing for the chance to catch a great haul, and bring a camera to capture the breathtaking scenery. For travelers who use our world travel planner, Marathon holidays become easier to arrange, with trips to the Old Seven Mile Bridge and other attractions mapped out and timetabled.
