Dom Luis I Bridge

The bridge is the shortest way to understand Porto's shape. A single wrought-iron arch spans the Douro gorge and carries two decks: the upper one, level with the cathedral terrace and the Serra do Pilar hill, takes the metro and a walkway; the lower one, down at quay level, links Ribeira and the port lodges of Vila Nova de Gaia and since April 2023 has been open only to public transport, taxis, cyclists and pedestrians. It opened in 1886 to a design by Theophile Seyrig, who had worked with Gustave Eiffel on the older railway bridge upstream. Crossing the top deck puts you above rooftops, boats and both riverbanks at once. The bridge was added by name to Porto's UNESCO listing in 2016.

History

In 1879 Gustave Eiffel proposed a high single-deck bridge over the Douro, but the growing city needed more, and a competition for a double-deck metal bridge opened in November 1880; on 21 November 1881 the work went to the Belgian Société de Willebroek for 402 contos, under Théophile Seyrig, Eiffel's former partner, who had also designed the Maria Pia railway bridge, hence the likeness between the two. It went up beside the towers of an earlier suspension bridge, the Ponte Pênsil, which was taken apart; the main arch and upper deck were finished on 30 October 1886 and opened the next day, with a toll of 4 réis a person, the lower deck followed the next year, and its 172-metre span was then the longest of its type in the world. The toll ended on 1 January 1944, trams crossed the upper deck from 1908 to 1959 and trolleybuses both decks from 1959 to 1993, and on 27 June 2003 motor traffic was taken off the upper deck to adapt it for the metro, which runs there today beside pedestrians (Wikipedia, Dom Luís I Bridge).

What you'll find

• The upper deck walk - rooftops, river and both banks from the level of the metro track.
• The lower deck - the quay-level crossing between Ribeira and the Gaia waterfront.
• Serra do Pilar terrace - the round cloister hill at the Gaia end, looking straight down the arch.
• The ironwork - riveted lattice and the single arch springing from the gorge walls.

When to go

Sunset draws the biggest crowd to the upper deck and the Gaia side, so arrive early for space at the railing. Mornings are quieter and the light falls on Ribeira instead. Winter is windy up top and the exposed deck feels it. The metro runs late, which makes an evening crossing easy.

What to expect

The upper walkway is narrow, shared with metro trains passing a metre away behind a low barrier, and crowds bunch on it at sunset. Anyone uneasy with heights should take the lower deck instead. The climb from Ribeira up to the top is steep, unshaded and longer than it looks. The lower pavement runs right beside the buses and taxis.

Nearby

Ribeira's quay, the Gaia port lodges and the Serra do Pilar cloister are all within ten minutes.
