Colle Isarco bridge

Properties

Element type

:

Civil engineering work

Civil engineering type

:

Road network Bridge

Year of construction

:

1969

Composed of materials

:

Reinforced concrete, Prestressed concrete

Description

:

This prestressed concrete box girder bridge consists of 13 spans making up a total length of 1029 meter. It was cast in situ and post-tensioned. The girder depth varies from 10.8 meter at mid-support to 2.85 meter at midspan. There is in total 494 prestress cables in the superstructure that create tension in all three directions. Being a complex engineering structure along the highway A22 with high intensive traffic, there is an interest in assessing the reliability and performance of the Colle Isarco bridge. The superstructure is statically determinate.
