The Pont del Diable (Spanish: Puente del Diablo, English: Devil's bridge), also known as Sant Bartomeu Bridge, is a medieval bridge crossing the river Llobregat and straddling the municipalities of Martorell and Castellbisbal in Catalonia, Spain. The bridge is restricted to pedestrians. The original Roman bridge formed a part of the Via Augusta, and was the only bridge in the lower Llobregat valley until the 14th century. It still features a Roman triumphal arch at its eastern abutment. It is unclear how many spans the original Roman bridge had.
