The Puente Romano (Spanish for Roman Bridge) is a Roman bridge over the Guadiana River at Mérida, Spain. It is the world's longest surviving bridge from ancient times, having once featured an estimated overall length of 755 m with 62 spans. Today, there are 60 spans (three of which are buried on the southern bank) on a length of 721 m between the abutments. Including the approaches, the structure totals 790 m. It is still in use, but was pedestrianized in 1991.
