It is located in the Douro Region, on the A24 motorway (when the road crosses the Douro River), city of Peso da Régua, district of Vila Real, in the Northern Region, sub-region of Douro
The Miguel Torga bridge crosses the Douro river valley at 90m high in a very rugged area, with large rocky outcrops and great natural wealth, close to Régua, also crossing the Douro railway line and two national roads.
Characteristics of the Miguel Torga Bridge
The work has a total length of 900 m and is curved in plan and profile with a 26m wide platform.
The structural solution adopted consists of a single continuous deck in a single-cell box with a variable section in height with 11 sections of which the main one over the river has a span of 180 m.
Transversely, the deck is made up of two 0.60m thick webs (0.70m in the 180m section and adjacent) connected by slabs and beams spaced 5m apart.
The deck is pre-stressed longitudinally, transversely in the slabs and upper beams with adhesive pre-stress and has devices for carrying out reinforcements through the use of pre-stress, either external (non-adherent) or internal (adherent).
The deck was built by successive cantilever advances using 5m staves and the work was entirely concreted “in-situ”.
The tubular shaft of the pillars has a constant section, with the necessary increase in section in the area at the base of the main pillars provided by four ribs of variable size.
The deck is supported by “pot-bearing” devices at the abutments and on pillars P1 to P6, being monolithically connected to the others.
The local rock formations are practically outcropping and have adopted direct, almost superficial foundations.

Completion of the work on the Miguel Torga Bridge
The work was completed in 1997 and received the Engineering Prize at the 1st Ibero-American Engineering and Architecture Biennial for its innovation and technological difficulty.
The Miguel Torga Bridge (1997), 900m long on the A24, was built by engineer Armando Rito in honor of the poet Miguel Torga with the pseudonym of Adolfo Correia da Rocha.
The area is rugged and has several rock formations, but the bridge that crosses the Douro River and is 90 meters high and 900 meters long crosses the Douro railway line and two national roads.

More panoramic views of the Miguel Torga Bridge
The best views are below the Bridge, on the N222 road, where you can see the road that crosses the river in a very pleasant stop in the Douro Demarcated Region following the Douro River.
The Miguel Torga Bridge has the peculiarity of being curved and visitors should take a boat trip in this area to see it up close.
