Dom Luís I Bridge (Ponte Luís I)

The two decks of the Dom Luís I Bridge

The bridge links Porto with Vila Nova de Gaia, the town across the Douro where the port wine cellars are. It has two decks, one high and one at river level, and both have pavements.

The upper deck, beside the metro

The top deck belongs to walkers and to metro line D, whose trains run down the middle. It’s about 390 metres long, five minutes or so at a steady pace, from the Cathedral side of Porto to Jardim do Morro, the garden and metro stop on the Gaia side.

Stop halfway and look downriver: the Ribeira’s houses run along the Porto bank, and the port lodges face them from Gaia. Visitors in 2026 pick sunset as the time to be up here.

Expect company, though. The pavements are narrow and full of people taking photos, and the trains pass close by. Between August and October 2026, some visitors found one side closed for works.

The lower deck, at river level

Down by the water, the lower deck runs between the Ribeira quay and the Gaia quayside. By day, walkers share it with buses, taxis and bikes, and at night, from 20:00 to 6:00, cars can use it too, under a rule in place since October 2023.

It’s also the gentler crossing for anyone who doesn’t like heights, and the place to see the iron arch rising over your head from bank to bank.

Crossing the Dom Luís I Bridge: free, and how to get up

Walking across is free on both decks, at any hour. The bridge charged a toll from 1886 to 1944 and has been free ever since; you’d only pay for a metro ride over the top.

From the river, the top deck is a climb. You can take the stairs up from the Ribeira, come round by the Cathedral, or ride metro line D from São Bento to Jardim do Morro.

Two shortcuts you’ll read about won’t help. The Guindais funicular has been closed for maintenance since July 2026, and STCP, which runs it, hasn’t given a reopening date. The Elevador da Lada only goes halfway up, to the Barredo quarter.

São João, Porto’s midsummer festival, is the one exception to the open hours. In 2026 the top deck closed to walkers at midday on 23 June, and the metro stopped crossing from 23:30 to 1:00, around the midnight fireworks.

To see the bridge from the water instead, the Six Bridges cruise that sails under it is one of the three tickets in the Highlights Pass.

Why the Dom Luís I Bridge looks like an Eiffel

The bridge gets credited to Gustave Eiffel. He didn’t design it, but the man who did had been his partner. Théophile Seyrig had worked with Eiffel on the Maria Pia railway bridge of 1877, a little upriver, and the family likeness shows.

This time Seyrig designed for a Belgian firm, the Société de Willebroeck, which won the contract on 21 November 1881. The new bridge replaced a suspension bridge on roughly the same spot.

The upper deck opened on 31 October 1886, and the bridge took the name of King Luís I, who was then on the throne. Its wrought-iron arch, 172 metres across, was the longest of its kind when it was built.

In 1996 the bridge went onto UNESCO’s World Heritage list, together with Porto’s historic centre and the Serra do Pilar monastery across the river.

Either side of the Dom Luís I Bridge

On the Porto side, the top deck starts just east of the Cathedral square, and from the square it’s about ten minutes on foot to Jardim do Morro. On the Gaia side, the Serra do Pilar monastery is about five minutes up from that metro stop.
