The Ponte Conde de Linhares, often shortened to Ponte de Linhares is a 3.2 km (2.0 mi) long causeway connecting Ribandar to the main city of Panjim in Goa, India. It runs along the flood plains of the Mandovi River and is surrounded by various salt pans. There are ducts which act as tide controls. The Ponte Conde de Linhares was built in 1633–34 under the direction of the then Viceroy of Portuguese India, Miguel de Noronha, 4th Count of Linhares, after whom it is named. The bridge is often said to have been the longest in the world at 3.2 km (2.0 mi) when it was completed in 1634.

A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges.
