Did you know that the Infante D. Henrique arch bridge in Porto was a milestone in the execution of concrete arch bridges?
The bridge, completed in 2002, represented a significant advance due to the magnitude of its dimensions:
– In its day, it turned out to be the second European concrete arch bridge, with a span of 280.0 m and the seventh in the world.
– It was a record in the type of laminar arches, with a constant depth of 1.50 m (approx. L / 186.7), extremely slender
– With a extremly reduced ratio rise/span (L/11.20), not seen until that date in arches of great span
