| shichor "The imperious, double-decker metal spans of Ponte de Dom Luís I stretch across the Douro River from Porto to Villa Nova de Gaia, and were designed by Téophile Seyrig, the student of Gustave Eiffel who also drew up the plans for the nearby Donna Maria Pia Bridge. When the Dom Luís I was finished in 1886, it was the longest single-span bridge in the world at 564 feet [172m], and it supported 3,045 tons of steel in weight. The bridge marked a significant step forward in Porto’s economic growth, as before it existed, the only passages across the river were boats lashed together. Today the lower deck of the bridge carries cars while the upper level is utilized by metro Line D and has a pedestrian walkway offering views across the river." (But this source, and others, say the Dom Luis I Bridge replaced a previous bridge.) |

| ulysses, this webpage has more photos "Built in 1806, this first version of the bridge, nicknamed 'Bridge of the Boats', consisted of 20 boats linked together, and which could be separated to make way for boats sailing on the Douro River (just like one of the earlier versions of the Rialto Bridge in Venice)." This bridge was destroyed in 1809 during the second Napoleonic invasion of Portugal. "Rebuilt after the tragedy, the bridge was later replaced by the Dona Maria II Bridge, a suspension bridge built in 1843, and then again by the Dom Luís I Bridge, which still stands today." |

| BridgeInfo, 1 of 5 photos "The bridge was designed by Téophile Seyrig who previously worked for Gustave Eiffel. Gustave Eiffel designed Maria Pia bridge which is also in Porto. Construction of Luís I bridge started in 1881 and the bridge was opened in 1886. When the bridge opened with a span of 172 meters [564'], it was the largest arch bridge in the world until 1898. In the upper deck runs Metro do Porto tram and in the lower deck is traffic." The total length is 385m (1263'), and the height is 45m (148'). Actually, the height is 44.6m (146'). [travel, but the opening year of 1876 on that webpage is a typo. And it also specifies a height of 60m (190'). That seems to be self-contradictory.] |

These are several photos I took late last year in Porto, Portugual of the Ponte de Dom Luis I Bridge over Rio Douro. Construction of the bridge was completed in October of 1886.The upper deck carries light rail trains and pedestrians while the suspended lower deck, which was undergoing restoration, is for pedestrians only.Per Wikipedia, the work was adminstered by Theophile Seyrig, who was a disciple of Gustave Eiffel.

| Midasoft "The inclination is necessary to minimize the torsional effects due to permanent loads and assure the 6 m vertical clearance between the cables and carriageway....The cables have a unique spatial arrangement due to the deck's curvature and tower inclinations. The structure has 18 pairs of cable stays in each of the four spans for 144 cables. Furthermore, steel consumption is 374,350 m (1,228,182 ft) of strand and 462 tons of steel." |

| FailedArchitecture "Considered by architects a great failure due to a number of reasons – from its patent ugliness to its inability to operate on an urban scale – Octavio Frias de Oliveira Bridge did succeed in what was apparently its main purpose: the endeavor of creating a global city image for São Paulo while covering up the city’s severe contradictions and conflicts. Octavio Frias de Oliveira Bridge – named after a Brazilian businessman responsible for creating one of the most influential media organizations in Brazil, the conglomerate Grupo Folha – was inaugurated on May 10th, 2008. The ceremony, attended mainly by politicians and high-profile businessmen, was accompanied by a small demonstration against the prohibition of pedestrians and bicycles on the bridge." |

| azvirt, 3 of 9 "The Bridge Počitelj crosses Neretva river with a single, continuous, 945 m long box prestressed concrete deck. Five main spans are 147 m long, while two side spans are 105 m long (105 + 5×147 + 105 = 945m)....The cross section of the piers, designed as a hollow thin walled box, has varying geometry as a function of structural loads, both in construction as in service. Piers are 92m, 97m, 92m, 91m, 88m and 66m high, respectively." The box-girder main spans have "variable depth being minimum 3,6 m [12'] in span centers and maximum 8,0 m [26'] at piers. All piers have monolithic connection to the superstructure. Both abutments as well as piers S1 and S6, are founded on shallow foundations, while piers S2, S3, S4 and S5 are founded on Ø1500 piles (25 pieces per pier). Piles are 25m (pier S2), 35m (piers S3 and S4) and 20-23m (pier S5) long." It is a 6-lane highway. |

| IRD Engineering "It is designed as a continuous prestressed girder bridge with a main span of 147 meters, variable box cross-section and a unique construction for both carriageways, and columns monolithically connected to the span construction, which is carried out by free cantilever construction." bnn also has this photo Aug 8, 2023: "Počitelj Bridge’s Sturdy Framework Receives Stamp of Approval from Stakeholders" "The meeting’s focal point was the disclosure of cracks on a specific segment — measuring 4.75 meters — out of nearly 200 segments constituting the bridge. These cracks, while concerning, were not unexpected given the intricacies of such a colossal project. The cracks emerged during the prestressing phase of the bridge’s construction, specifically on segment 15. However, as experts explained, the occurrence of such defects during ongoing construction is a known challenge, particularly considering the magnitude and complexity of the undertaking....A technical analysis illuminated the causes behind the emergence of cracks. Minor alterations in cable geometry were identified as factors contributing to increased tensile stress in the concrete structure. The intricacies of cable duct positioning during construction were shown to create forces leading to localized cracks. Such insights highlighted the need for meticulous attention to detail and precision in every stage of construction." The article continues with more sweet words about "challenges" and cooperation, but it doesn't say anything about how they plan to fix the bridge. |
