The old Kalix Bridge has found a new home at LTU

Published: 9 November 2022

The old bridge was built in the 60s and was a very important part of the E4 road infrastructure. In 2015 the bridge was deemed unfit for increased heavy traffic and a new bridge was build downstream.

The old concrete bridge in Kalix has now been successfully demolished. In this process a big slice was saved and transported to LTU for further research activities.

“In the first part of the project we have investigated the capacity of the old bridge and possible shortcomings to increase our understanding of the risks that old bridges can pose. With advanced equipment we have collected data when heavy traffic was travelling over the bridge in both directions under controlled conditions. We have also scanned the bridge at different locations to find out what defects might be hidden inside. In the next phase of the project, we will look into verifying those measurements and see how the tools can be calibrated for further use on other bridges of the same type,“ says Gabriel Sas, Professor and Head of the research subject  Structural Engineering at the university.

“Now we are in the final phase of reporting the project results so far, and of planning for the next phase of financing the project,”  says Jaime Gonzalez, project manager och postdoctoral in the same group.
