Beam bridges (Isostatic)
Introduction
Gasset Bridge was a bridge in the city of Burgos (Castilla y León, Spain).
History
The works began in 1924, with the engineers of the Duero Hydraulic Division being the ones who contributed the most to the decision on the final design of the bridge, with Virgilio García Antón directly participating.
The work was awarded to the contractor Alberto Corral with a value of 215,574 pesetas.
The inauguration of the bridge took place on March 3, 1926, to which a large part of the local authorities and a large part of the delegates from the ministries were invited. A civic-religious procession was organized, which started from the church of San Lesmes "Iglesia de San Lesmes Abad (Burgos)"). A tribune was also installed on the Paseo de la Quinta, decorated with pennants and flags, from where the institutional speeches were given where the mayor, at that time Ricardo Amézaga, and the general director of public works, Rodolfo Gelabert, intervened. The events ended with an official banquet.
The first renovations took place in 1928 when 4 streetlights were installed.
In 1934 its sidewalks were built, and in 1944 important improvements were made to the environment as the approaches to the bridge were paved.
The following decades saw few improvements and the bridge suffered great deterioration, which is why in 2000 the possibility of carrying out a general reform was raised but the work was paralyzed. In 2005 the idea of increasing the dimensions of the bridge began to be considered. This took place in 2009 when David Hernández said that the bridge was going to be changed for one with greater capacity. That same year, the report prior to the execution of the reform maintained that the bridge had serious structural problems.
In May 2010, demolition began along with its reconstruction. On March 14, 2011[1] it was inaugurated, being nicknamed the Bridge of Evolution, being next to the Museum of Human Evolution and adding itself to the list of the Bridges of Burgos.
What is it made of?
In its beginnings, the bridge was made up of five isostatic spans, these formed by reinforced concrete beams and supported by two abutments and four intermediate pillars.
After the renovation carried out in 2010, the result was a unique concrete structure with three openings, two piers with embedded post deck, and three support pillars. The board has curved profiles that give it great mobility along with great visual complexity.
