Ronfes Bridge (Leça do Balio):
This bridge, built with three round arches, was part of a regional circulation route that is referred to in medieval documentation as the Karraria Antiqua and whose origin goes back to a secondary road from Roman times. This road came from Cedofeita, through Monte dos Burgos, going through Padrão da Légua, Gondivai and Araújo, to the Maia region.
 
D. Goimil Bridge (Custóias):
Trestle bridge with a pointed arch, built in irregular granite masonry, presenting a constructive typology characteristic of the Middle Ages (13th - 14th centuries). A road passed through this place, probably of Roman origin, with some regional importance. It appears referenced in medieval documentation as the Via Veteris or the Estrada Velha. It started next to the Douro River, in the Arrábida area and, coming from Couto between Lordelo and Cedofeita, it passed by the Cruise of Santiago de Custóias, crossed the river Leça in this place and from here it was driven by Pedras Rubras, Aveleda, Modivas and Vairão to the Ave River estuary. It is an interesting example of medieval public civil architecture classified as a Public Interest Building by Decree 516/71 of 22 November.
 
Guifões Bridge (Guifões):
This bridge, now disappeared, was located at the foot of Castro de Guifões, next to the estuary of the River Leça. It was built in regular granite masonry and composed of three round arches. It also had very characteristic granite guards, whose typology seems to fit it chronologically in the Middle Ages. However, its foundation can go back to Roman times, integrating itself on the coastal route that “per loca maritima” connected to the Ave estuary and Vila do Conde, passing by the Roman villa of Lavra. This bridge collapsed during a flood on the Leça River in 1979.
