Tampico bridge |
The
Tampico bridge (
Spanish:
Puente de Tampico) is a vehicular
cable-stayed bridge in
Mexico, located on the
Pánuco River in the city of
Tampico,
Tamaulipas, near to the
Gulf of Mexico. The bridge has been in service since
1988 and was designed by Professor Modesto Armijo from COMEC, a Mexican engineering company. It was designed to withstand the severe
hurricanes of the
Gulf of Mexico. It connects the states of
Tamaulipas and
Veracruz.
The bridge uses an
orthotropic steel deck girder for a central section of the 360 m long main span, while the rest of the main span and the short lateral spans are a
prestressed concrete girder. Both steel and concrete deck girders have the same external shape. This original principle was later used at the
French Normandy cable-stayed bridge (756 m main span).
The dynamic analysis of the bridge under
turbulent cyclonic winds, as well as the revision of the structural project, and the geometry plus stress control of the bridge during erection, were achieved by Alain Chauvin from Sogelerg, using the
French "Scanner" computer program.
