MAURER supplies expansion joints, bearings, and dampers for bridge and viaduct projects. One of MAURER’s global projects in this area is the Çanakkale Bridge project in Turkey.

The Çanakkale Bridge is the largest suspension bridge in the world, with its main span measuring 2,023 m. The total bridge length is 4,608 m, and the width is 45 m.

The expansion joint installed in this project has some unique features. One of them is the MSM Swivel Joist Expansion Joint, which ensures displacement of 2,800 mm. The swivel joist feature allows the bridge to move in all directions. The sliding distance is up to 50 km.

Another interesting feature is absorbing up to 60% of noise thanks to the special technology used in the expansion joint.

In this project, the expansion joint is supported by not classic elastomers but new W-shaped MSM bearings. This is one of Maurer’s new patents, obtained in 2020. This allows for improved performance, elimination of limitations, and an extended product lifespan.
