Wiesenbrücke
Project description
The Wiesenbrücke crosses the river Wiese in the area of the Freiburgerstrasse. The structure is located below the N02 freeway and is part of the local road network of the city of Basel at the Basel-Kleinhünigen junction. The structure consists of two supporting structures, whereby the second bridge was built years later due to the increasing traffic volume.
The particular challenge for the expansion joints are the two bridges, which have different movements due to being built in different designs. For example, a longitudinal joint had to be integrated into an oblique transverse joint.
mageba scope
In addition to the geometric flexibility, another crucial factor in the selection of the joint was the lowest possible noise emission with low maintenance costs and the possibility of phased installation within very short time windows. By using the flexible plug joint TENSA®POLYFLEX®Advanced PU and a special fly-over system, traffic could be maintained at 100 % during the day and only during nighttime hours individual lane closures occurred.
The existing linear rocker bearings were in a condition worthy of preservation and were undergoing restoration only.
