Completed in 2003, the Infante Bridge carries vehicle and pedestrian traffic from Vila Nova de Gaia to Central Porto. The bridge was constructed as a replacement for the upper deck of the Dom Luís I Bridge that was closed to vehicle traffic in 2003 to allow for its conversion to the D Line of the Porto Metro.[1]
The bridge has a total length of 371 metres (1,217 ft) and an arch span of 280 metres (920 ft).[2] The bridge's height is 75 m (246 ft) above the Douro River, but the height of the arch is only 25 m (82 ft) above its foundations in the riverside cliffs. Inspired by the alpine Maillart bridges, the Infante Bridge's arch is one of the shallowest in the world as a ratio of rise from base over length.[3]
