The Bridge of Cava da Velha (Portuguese: Ponte Velha/Ponte da Cava da Velha) is a Roman bridge, situated in the civil parish of Castro Laboreiro e Lamas de Mouro, in the municipality of Melgaço in northern Portuguese district of Viana do Castelo.

The name Ponte Nova indicates the existence of another structure constructed in the same local (or nearby) at one time anteceding the current bridge.

[1] This may actually be the nearby Ponte de São Brás or Ponta da Assureira.

The bridge linked the Roman road to Espanha through Portela do Homem, passing through Estrimo (in Spain), Ameixoeira, Porto do Vaga and Assureira - Cova da Velha - Varziela - Castro Laboreiro.

[1] The bridge is situated in an isolated, rural area within the Nature Park of Peneda do Gerês, 110 metres (360 ft) east of the municipal roadway over the River Laboreiro, 3 kilometres (1.9 mi) from Castro Laboreiro.
